Cudis 13A 30mA Type A RCD Metal Fused Spur Unit | SU13M

The Cudis SU13M 13A 30mA Type A RCD Metal Fused Spur Unit combines fused connection and residual current protection in a durable metal-clad plate, making it ideal for commercial, industrial, and heavy-use environments.

Designed to protect fixed appliances and dedicated circuits, this RCD fused spur provides 30mA Type A residual current protection, detecting both AC and pulsating DC leakage currents. A built-in test button allows easy verification, while passive type latching ensures the device will not automatically reset after a power interruption improving safety for connected loads.

Compliant with BS 7288:2016 and BS 1363, the SU13M is well suited to boilers, heaters, fans, and other permanently connected equipment where additional protection is required.
