The Allen-Bradley 1492-SPM3C020-N Series D is a supplementary protector and miniature circuit breaker designed for overcurrent and short-circuit protection in industrial and commercial electrical systems. Featuring a 3 Pole + Neutral (3+N) configuration, this device is suitable for protecting control circuits and electrical distribution applications where multi-pole protection is required. The unit has a 2A current rating and supports operating voltages of 400V AC under IEC standards and 480Y/277V AC under UL/CSA standards. Its C characteristic trip curve makes it suitable for circuits requiring medium magnetic trip characteristics. The breaker offers an interrupting capacity of 15kA Icu and 11.25kA Ics and is designed for DIN rail mounting, allowing straightforward installation in control panels, switchboards, and industrial electrical assemblies.
