Product details

The 12 A continuous rating is the load current it carries without tripping; pair it with a contactor rated for the same motor FLA.

Spring-loaded terminals on both main and auxiliary/control circuits accept 2x (0.25... 2.5 mm²) solid or stranded wire (2x (24... 14) AWG). No tools needed for termination — a time-saver on repeat builds. The 45 mm width leaves room for adjacent contactors on the same rail. Any mounting position is permitted. IP20 front protection covers the terminals against accidental contact.
