1492 Energy limiting circuit breakers are thermal magnetic type supplementary overcurrent protective devices. 2 and 3-pole devices are connected internally and at the handle for simultaneous operation. Wire termination is achieved by a clamping style, self-lifting box lug on all 1492-CB units. Both line and load side termination points will accept #16 to 6 AWG (1.5 to 16 mm.) copper wires. Field-mountable options for selective applications. True IP2X finger-safe design (top and sides). International approvals - CE marked, meets UL, CSA and IEC (VDE) standards for worldwide acceptance. A positively trip-free mechanism (breaker operation cannot be defeated by holding the handle in the ON position). Superior shock and vibration resistance capabilities - helps to prevent nuisance tripping. Mounts on DIN Rail or optional through door brackets. On standard AC/DC versions (F, G, H) line and load connections may be reversed.
