700-K40E-D

Overview of Allen Bradley 700-K40E-D

The Allen Bradley 700-K40E-D is a 4-pole miniature control relay crafted for reliable switching in industrial control panels and automation systems. Featuring 4 normally open contacts and a coil rated at 110/120V AC, this relay is designed for easy integration on standard 35mm DIN rails. It is a favored choice among panel builders and OEMs due to its compact form, screw terminal connections, and a 10 AMP rating. Its compatibility with top-mounted auxiliary contact blocks allows expansion up to 8 contacts in any combination, supporting complex control schemes as requirements grow. The 700-K40E-D is UL and IEC certified, supporting long operational lifespans (rated for up to 300,000 cycles), which helps reduce maintenance and equipment downtime.
