Allen-Bradley 1492-SP3C320 Selector Switch 30mm

Allen-Bradley 1492-SP3C320 is a three-pole supplementary protector (circuit protector) rated for 32 A with a C-trip curve, designed to protect control circuits in AC systems. It is specified for UL/CSA 480Y/277 VAC operation, with the standard model offering protection without a neutral and a -N variant (1492-SP3C320-N) that provides a neutral connection for three-phase circuits that require it. This device is typically used with contactors and control panels to interrupt fault currents quickly and safely, and it belongs to Rockwell Automation’s 1492-SP family of protective devices for compact, modular protection in industrial equipment.
