Product details

Panel fit and mounting constraints

The 3RH2353-1DF40-0KA0: Its dimensions are 57.5 mm height, 45 mm width, and 121 mm depth — the depth figure is the critical dimension for gland-plate clearance in shallow enclosures.

Contact ratings and switching duty

This auxiliary contactor carries 4 normally open (NO) and 1 normally closed (NC) instantaneous contacts. The coil is rated 110 VDC with a closing power of 4 W and includes a built-in varistor for surge suppression — this eliminates the need for an external snubber on the coil circuit.

Environmental and compliance documentation

The substance prohibition date per RoHS is 07/01/2006, confirming RoHS compliance for the European market.
