Description

The 20 Amp 30mA RCBO from Hager is designed for use with Hager Commercial and Industrial Distribution Boards. This single-module device combines an MCB (Miniature Circuit Breaker) and an RCD (Residual Current Device) into one unit. Thus providing both overcurrent and earth fault current protection. The RCBO has a 30mA sensitivity, and a short circuit breaking capacity of 10kA.  Hager has improved the design of its Commercial RCBO range, making it easier for installers to use. The new design allows for insulation resistance testing of final distribution circuits without the need to disconnect the RCBO. Additionally, when the RCBO is in the ‘off’ position, a 500V DC test can be safely performed without causing any damage to the device. The RCBO is rated for 20A, with a residual operating current of 30mA, and offers reliable protection for commercial and industrial installations.
