Why Choose the IMO B10R40100-100-S Selective Residual Current Circuit Breaker?
The IMO B10R40100-100-S is a high-quality Selective Residual Current Circuit Breaker (RCCB) designed to provide dependable earth leakage protection for commercial and industrial electrical installations. Manufactured by IMO Precision Controls, this four-pole RCCB incorporates a time delay (Type S) characteristic, allowing discrimination with downstream protective devices while maintaining excellent protection against earth fault currents.
Manufactured in accordance with IEC 61008-1, the B10R40100-100-S offers reliable protection for three-phase electrical systems. Its selective tripping characteristic reduces unnecessary power interruptions by allowing downstream RCCBs to operate first, making it particularly suitable for larger distribution systems and coordinated protection schemes.
With a 100A rated current, 100mA residual operating current, Type AC Selective (Type S) protection and a 415V AC three-phase plus neutral supply, the IMO B10R40100-100-S is ideal for industrial distribution boards, commercial premises and electrical installations requiring coordinated residual current protection.
