SIEMENS (TYPE BLEH) 1 POLE 20 AMP GFCI CIRCUIT BREAKER 120VAC UA-22kA - New! Plus Free Shipping In US 48!
New, but does not include original box.
Siemens Type BLEH 1P 1-phase thermal magnetic molded case circuit breaker rated at 20 AMP/120 VAC, features a load lug terminal and is a 30 MAMP equipment protection device and ground fault circuit interrupter. It is suitable for use in areas where instant limiting of short-circuit current is required during heating, air conditioning and refrigeration. When the current flow in an electric circuit exceeds 22 KAMP, this breaker trips and protects the circuit. Siemens looks forward to bring innovation in technology, process automation and other manufacturing process for resulting in increased sustainability. Thermal magnetic circuit breaker includes a bimetal switch and an electromagnet as switching mechanisms. Situated behind a trip bar of the breaker is a bimetal, which is one of the current carrying paths. Exceeding electrical current than the rated overload current of the breaker, heats the bimetal, causing it to bend and touch the trip bar to open the circuit. An iron core with a wire coil around it forms an electromagnet. This electromagnet responds to short-circuit currents when load current passes through the electromagnet. When a high-level of current passes, the electromagnet generates enough field strength and attracts a nearby armature. The armature rotates as soon as its top moves towards the electromagnet and the trip bar trips the breaker, disconnects the current path and de-energizes the electromagnet coils. This safety device is bolt-on mountable and comes integrated with long-time and instantaneous trip functions.
