General Electric TKM Series circuit breakers are designed to provide feeder and branch circuit protection in motor load centres, busbars and panelboards. The molded case of these breakers holds the current-carrying components, trip devices and mechanisms within a very small space. These UL-listed circuit breakers feature a thermal-magnetic, non-interchangeable trip unit capable of overriding mild overloads but instantly reacting to severe current spikes for maximum current limiting protection. They further come equipped with line- and load-side lug terminals with a feed-thru connection for reducing the installation downtime. Choose from a wide range of these circuit breakers, available in amperage ratings of 300, 350, 400, 450 and 500A on Raptor Supplies.
