Eaton Specification Sheet - ER12-30J3PB
Enclosed rotary disconnect switch with fuse class J compatibility delivers a safe, visibly isolated circuit with downstream overcurrent protection, reducing arc flash risk and simplifying protection coordination in motor circuits and feeders. The pistol handle design enhances operability during maintenance and lockout/tagout, improving worker safety while enabling quick, repeatable disengagement. With a 600 V/30 A rating, the switch accommodates typical plant motors and feeders, supporting reliable control without overloading downstream devices. The NEMA 12 enclosure offers entry protection against dust and moisture, extending service life in dusty workshops or humid environments. CE compliance ensures international safety standards are met, enabling cross-border deployment for OEMs and integrators. Precise dimensions (13.6 in depth, 12.3 in height, 13.5 in width) simplify panel integration and spare-part matching.
