3P series L-Frame molded case circuit breakers offer branch or feeder circuit protection against overload or short circuits. L-Frame 3-pole breakers, with adjustable thermal magnetic trip, are available in current capacities of 400 to 600A at 600VAC/250VDC (UL489 rating). Kits that include an aux contact, shunt trip or undervoltage release are also offered.
These 3 pole breakers are designed to provide branch and feeder circuit protection in industrial control panels. The 3P Series Molded Case Circuit Breakers provide overload protection in conductors and short circuit protection in connected equipment such as motors. Shunt trip breakers and other accessories are easily installed in the field for these frame sizes.
They are UL listed for installation in UL 508 control panels. Their small size, in relation to standard circuit breakers or other comparable devices, saves panel space.
