Product details

Rated currents and voltage breakpoints

The 3RH2140-1AN00: For DC-12 switching the maximum operating frequency is 1,000 operations per hour — relevant when the contactor is cycled by a fast timer or PLC output.

Physical fit and panel clearances

Dimensions are 57.5 mm high, 45 mm wide, and 73 mm deep — the width is the tightest axis; side clearance to adjacent devices should be at least 6 mm for airflow and arc dissipation.

Surge voltage resistance is 6 kV, and the substance prohibition date (RoHS-like) is 10/01/2009, so it meets EU material restrictions for current production.

Frequently asked questions

What is 3RH2140-1AN00's listed depth and width?
