NGB2B125B - Siemens Bolt-On Molded Case Circuit Breaker

The Siemens NGB2B125B 2 Pole Circuit Breaker can be installed in a panel board for effective protection of electrical appliances. It offers thermal-magnetic protection to counter overload conditions and dangerous overcurrent. The NGB2B125B is a heavy-duty circuit breaker with a high interrupting rating of 10 kAIC at 240 VAC and 25 kAIC at 480 VAC. When the overcurrent surpasses a threshold value during fault conditions like a short circuit the circuit breaker is tripped by its electromagnetic mechanism to prevent appliances from damage. The circuit breaker comes with a bolt-on mount for a convenient installation experience. It has voltage and current ratings of 600 VAC and 125 Amp.
