Product details

Panel fit and switching capacity

The 3RH2244-4BN40: The 45 mm width and 117 mm depth fit the standard S00 footprint — the same as the matching 3RT2 contactor it piggybacks on or sits beside.

Environmental limits and compliance

The surge voltage resistance is rated at 6 kV, which aligns with IEC 60947-1 overvoltage category III for 400 V systems.

Frequently asked questions

What is the 3RH2244-4BN40 used for?

It is an auxiliary contactor — four NO contacts used for control-circuit switching, typically to extend the number of auxiliary contacts on a main contactor or to interlock signals in a motor control centre.

How is the 3RH2244-4BN40 supplied and quoted?

This part is sourced through independent distribution channels and quoted to order against the buyer's BOM quantity.
