Live Electrical RNC106B-030N 6A Plug-On Neutral Compact Bi-Directional RCBO

6A B Curve 30mA Type A 1P+N Bi-Directional RCBO for Live Electrical SRN Consumer Units

The Live Electrical RNC106B-030N is a compact 6A B Curve 30mA Type A bi-directional RCBO specifically designed for compatible Live Electrical SRN plug-on-neutral consumer units.

Combining overload, short-circuit and residual-current protection within a compact single-module device, the RNC106B-030N provides a convenient circuit protection solution for appropriately designed low-current circuits.

Its plug-on-neutral design eliminates the conventional flying neutral lead, helping create a cleaner consumer unit layout and simplifying installation when used with compatible Live Electrical SRN dual busbars. The device is also bi-directional, providing additional flexibility for modern electrical installations where current may flow in either direction.

With a 6A rating, B Curve characteristic, 30mA residual-current sensitivity, Type A protection and 6kA breaking capacity, the RNC106B-030N is particularly suited to appropriately designed lighting and other low-current circuits within compatible SRN installations.

Combined RCBO Protection

The RNC106B-030N is an RCBO – Residual Current Circuit Breaker with Overcurrent Protection.

Unlike an MCB, which provides overcurrent protection, an RCBO combines multiple protective functions within one device.

The RNC106B-030N provides protection against:

• Overload
• Short Circuit
• Residual / Earth Leakage Current

This allows an individual circuit to receive both overcurrent and residual-current protection from a single compact protective device.

6A Current Rating

The RNC106B-030N has a rated current of 6A, making it suitable for appropriately designed circuits requiring a 6A protective device.

A common application for a 6A B Curve RCBO is an appropriately designed lighting circuit, although suitability must always be determined from the complete electrical circuit design.

Cable size, installation method, design current, connected load, fault conditions and applicable BS 7671 requirements should all be considered when selecting the protective device.

B Curve Tripping Characteristic

The device features a B Curve tripping characteristic.

B Curve circuit protection is commonly used for suitable domestic and light commercial circuits with relatively low expected inrush currents.

The correct tripping curve must always be selected according to the characteristics of the connected equipment and circuit.

30mA Residual Current Protection

The RNC106B-030N has a rated residual operating current of 30mA.

This allows the RCBO to detect residual-current faults while simultaneously providing conventional overcurrent protection.

The combination of 6A overcurrent protection and 30mA residual-current protection makes the unit a convenient all-in-one protective device for compatible SRN installations.

Type A RCBO

The RNC106B-030N is a Type A RCBO.

Type A residual-current protection is designed to respond to sinusoidal AC residual currents and pulsating DC residual currents, making it appropriate for many modern electrical loads containing electronic components.

This makes Type A protection increasingly relevant in contemporary domestic and commercial electrical installations.

Bi-Directional Operation

A major feature of the RNC106B-030N is its bi-directional design.

The device is designed to operate with current flow in either direction, providing increased flexibility where the electrical installation requires bi-directional circuit protection.

This characteristic can be particularly relevant in modern installations involving distributed generation and other circuit arrangements where power flow may not always follow the traditional supply-to-load direction.

The complete electrical installation and protective-device requirements must still be assessed before use.

Plug-On Neutral Design

The RNC106B-030N uses a plug-on-neutral connection system designed specifically for compatible Live Electrical SRN consumer units.

Rather than using a conventional flying neutral lead from each RCBO, the device connects into the compatible SRN dual busbar arrangement.

This provides a cleaner and more organised method of installing individual RCBO protection within the consumer unit.

No Flying Neutral Lead

One of the principal installation benefits of the RNC range is the elimination of the conventional flying neutral lead.

Removing individual flying leads can help produce a cleaner consumer unit layout, reduce cable congestion and simplify access to other terminations.

The plug-on-neutral arrangement is, however, specific to the compatible SRN consumer unit system and should not be confused with conventional flying-neutral RCBO designs.

Compact Single-Module Design

Live Electrical officially specifies the RNC106B-030N as a single-module 1P+N RCBO.

Its compact format allows individual circuits to receive combined overcurrent and residual-current protection without unnecessarily consuming additional consumer unit space.

18mm, consistent with its single-module design.

1P+N / Double Pole Arrangement

1P+N.

Retailers also commonly describe the product as a double pole RCBO, reflecting its switched line-and-neutral arrangement.

Using 1P+N

6kA Breaking Capacity

The RNC106B-030N has a 6kA short-circuit breaking capacity.

The required breaking capacity must be suitable for the prospective fault current at the point of installation and should be considered as part of the overall electrical system design.

230V AC Rated

The device is rated for use on a 230V AC electrical supply.

Live Electrical's current official product page confirms the RNC range designation, 6A rating, B Curve characteristic, Type A classification, 30mA residual-current rating and 6kA short-circuit capacity.

Designed Specifically for SRN Consumer Units

Compatibility is particularly important with the RNC106B-030N.

The device is designed to complement Live Electrical SRN consumer units using the compatible dual busbar / plug-on-neutral system.

It should not be assumed to fit conventional consumer units simply because it uses a compact modular format.

Retailer documentation specifically identifies compatibility with Live Electrical LSMCSRN consumer units and states that the RNC106B-030N is not suitable for standard consumer units or installations requiring conventional flying-neutral RCBOs.

SRN Dual Busbar Compatibility

The Live Electrical SRN system uses a dedicated dual busbar arrangement, allowing the RNC plug-on-neutral devices to connect without individual neutral flying leads.

This system can provide a cleaner internal consumer unit layout while retaining individual RCBO protection for each applicable circuit.

The RNC106B-030N should therefore be purchased only after confirming that the existing consumer unit is a compatible Live Electrical SRN model.

Important Compatibility Information

The Live Electrical RNC106B-030N is specifically designed for the Live Electrical SRN plug-on-neutral consumer unit system.

It is not a universal RCBO and should not be assumed compatible with standard consumer units or consumer units requiring conventional flying neutral connections.

LSMCSRN consumer units fitted with the appropriate Live Electrical dual busbar arrangement.

Always confirm the exact consumer unit model and busbar system before ordering an additional or replacement RNC RCBO.

RNC106B-030N vs CN106B

Although both devices have a 6A B Curve rating and are associated with compatible Live Electrical SRN installations, they perform different protective functions:

• CN106B – 6A B Curve Bi-Directional MCB
• RNC106B-030N – 6A B Curve 30mA Type A Bi-Directional RCBO

The key difference is that the RNC106B-030N incorporates 30mA Type A residual-current protection in addition to overcurrent protection.

This distinction is important when specifying circuit protection, as an MCB and RCBO should not be treated as interchangeable simply because their current and curve ratings are the same.
