Panel fit: S00 frame on DIN rail with flexible orientation
The 3RH2440-1BB40: The S00 frame measures 57.5 mm high, 90 mm wide, and 73 mm deep — the 90 mm width is the critical dimension for rail spacing in a multi-row panel layout. The 6 mm side clearance is the tightest constraint — adjacent contactors or terminal blocks must respect this for arc flash and heat dissipation.
Environmental and compliance envelope
The 10 % minimum relative humidity rating means the contactor can be installed in dry, climate-controlled panels without condensation concerns. RoHS compliance date is 10/01/2009 — the part meets the EU RoHS substance restrictions as of that date. The auxiliary switch extension capability (Product Extension Auxiliary Switch: Yes) allows field addition of a side-mount block without derating the main contacts. Mechanical life is 5,000,000 operations typical — the switching frequency of 10,000 ops/h AC means the mechanism is rated for about 500 hours of continuous cycling at full rate before wear-out.
