2 & 4 Pole RCCB - FH200 Series

Compact AC DIN rail mount 2 and 4 Pole RCCB’s
Protects against the effects of sinusoidal alternating earth fault currents
Protects against indirect contact with additional protection against direct (with IΔn=30 mA) contact
Command and isolation of resistive and inductive circuits
Suitable for residential and commercial applications

Note

RCCBs are sensitive only to earth fault current (therefore they have to be connected in series with a MCB or a fuse to protect them against over-current and short-circuits).
