Schneider Electric CA2KN31U7 Control Relay 3NO/NC 230-240V

Product Description

The SCHNEIDER ELECTRIC CA2KN31U7 is a control relay designed for AC control circuits operating at 230-240 volts at 50/60 Hz. It features a 3NO/NC contact configuration, making it suitable for switching and control applications in industrial and commercial electrical panels. The relay mounts on standard DIN rail and uses screw terminals for fast, secure field wiring. It carries UL Listed status along with IEC 60947 and RoHS compliance, meeting the certification requirements common to commercial and industrial installations. Licensed electricians and controls technicians are the primary installers for this device.

The CA2KN31U7 is used in control panel builds, machine control circuits, and building automation applications where a DIN rail-mounted relay is required. It is suited for both new panel construction and replacement service in existing equipment. Its IP2X ingress protection rating indicates it is intended for use inside enclosures rather than in exposed or wet locations. The operating temperature range of -13.0 degrees F to 122.0 degrees F makes it appropriate for standard indoor industrial environments.

Key Features

• 3NO/NC contact configuration for versatile switching arrangements
• 230-240 VAC coil voltage at 50/60 Hz for compatibility with standard AC control circuits
• DIN rail mount for quick installation in standard control panels
• Screw terminal connections for reliable, tool-accessible field wiring
• UL Listed, IEC 60947, CSA, and RoHS compliant for broad code acceptance
• Minimum sensed amperage of 5 milliamps suitable for low-signal control applications

Compatibility

Designed as an OEM-style replacement or new-build component for standard DIN rail control panels and industrial control circuits requiring a 3NO/NC AC control relay at 230-240 VAC 50/60 Hz.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out the control panel before installing or replacing this relay. Confirm coil voltage and contact configuration match the circuit design before wiring. The relay is rated for use inside an enclosure due to its IP2X ingress protection rating and should not be installed in exposed or wet locations.
