Schneider Electric CA4KN31BW3 Control Relay 3NO/NC 24V

Product Description

The SCHNEIDER ELECTRIC CA4KN31BW3 is a DC low-consumption control relay rated for 24 VDC operation with a 3NO/NC contact configuration. It is designed to switch and control low-voltage circuits in industrial and commercial electrical systems. The relay's low-consumption DC control circuit reduces energy draw on the coil, making it well suited for automation panels, motor starter auxiliary circuits, and building control applications. Licensed electricians and automation technicians are the primary installers of this type of control relay.

This relay fits into control panel assemblies where auxiliary contact blocks or standalone relay functions are required. It is applicable in commercial building automation, light industrial machinery control, and HVAC electrical control circuits that require reliable DC-coil switching. The 3NO/NC contact arrangement provides flexibility for interlock, signal, or alarm circuit wiring within the same device footprint.

Key Features

• 3NO/NC contact configuration for flexible circuit wiring
• 24 VDC coil rating with DC low-consumption control circuit
• Compact form factor suited for panel-mount installations
• Single-unit packaging for direct replacement or new installation

Compatibility

Designed as an OEM-style replacement or auxiliary control relay for low-voltage DC control circuits in industrial and commercial electrical panel applications.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the control panel before removing or installing the relay. Verify coil voltage and contact rating match the circuit requirements before energizing. Follow the manufacturer wiring diagram for proper contact terminal assignment.
