Niglon Protego 25A 3 Phase Type A 10kA B Curve RCBO | PRCBO10B3-25
SKU: PRCBO10B3-25
Brand: Niglon
The Niglon Protego 3 Phase RCBO is a compact, all-in-one protection device designed specifically for use within Niglon Protego 125 TP&N three-phase distribution boards. This RCBO combines overload, short-circuit, and residual current protection in a single device eliminating the need for separate RCD enclosures.
Niglon Protego 25A 3 Phase Type A 10kA B Curve RCBO | PRCBO10B3-25
The Niglon PRCBO10B3-25 Protego 3 Phase RCBO is a compact, all-in-one protection device designed specifically for use within Niglon Protego 125 TP&N three-phase distribution boards. Rated at 25A, this RCBO combines overload, short-circuit, and residual current protection in a single device eliminating the need for separate RCD enclosures.
Previously, providing RCD protection on three-phase circuits often required additional enclosures and complex wiring. The PRCBO10B3-06 solves this by fitting directly into the Protego 125 board, saving space, reducing installation time, and simplifying compliance with BS 7671.
With a Type A RCD function, 30mA residual current sensitivity, and a 10kA breaking capacity, this RCBO delivers reliable protection for modern three-phase installations where DC residual currents may be present.
