Do you need overload or short circuit protection for your industrial control panels or equipment? These Molded Case Circuit Breakers from Eaton Cutler-Hammer are designed to provide branch and feeder circuit protection in industrial control panels. They also supply protection against overload in conductors and short circuits in connected equipment such as motors.These MCCBs 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. Four frame sizes and all standard accessories are available.
MCCB prices start at
$167.25
(G3P-015)
Features include:
- UL489 listed performance for branch circuit overcurrent protection and disconnecting means
