Siemens BLH B120H00S01 Shunt Trip Circuit Breaker

Siemens BLH B120H00S01 is a 1-pole, 20-amp, 120-volt shunt-trip circuit breaker designed to provide overcurrent protection with remote shutdown capability. The shunt-trip functionality allows a separate control signal to trip the breaker, enabling rapid isolation of a 120 V circuit in safety interlock or emergency shutdown scenarios. The unit is identified by the part number B120H00S01 and is intended for single-pole protection in industrial or commercial electrical distributions. Use this Siemens breaker where remote tripping and reliable 20 A protection at 120 V are required, and ensure compatibility with your panel or enclosure before installation.
