Allen-Bradley 700-K40E-* Control Relay Series B

Allen-Bradley 700-K40E-* is a Series B control relay with four normally open contact poles. It is built for switching control circuits through an A1/A2 coil connection and labeled IEC and UL electrical ratings. The compact format supports panel-based automation and control wiring.

- Coil power applied at terminals A1 and A2 actuates the internal relay mechanism.
- Relay actuation opens and closes four independent NO contact paths across 13-14, 23-24, 33-34, and 43-44.
- Screw-terminal contact points support hard-wired integration into control circuit layouts.
- Multi-pole switching enables one relay action to control several circuit paths at the same time.

- 4 normally open contact configuration identified as 40E.
- IEC / EN 60947-5-1 marking with impulse withstand rating of 6 kV.
- AC-12 rating marked 690V at 10A.
- AC-15 ratings marked as 24V 3A, 120V 3A, 240V 2A, and 400V 1.2A.
- UL marking shows 600V AC max. 10A with B600 / Q600 designation.

- Switching control circuits in industrial automation systems.
- Relay logic and panel control wiring where four NO poles are required.
- General control applications using IEC and UL marked relay components.
