Schneider Electric CA2KN40M7 Control Relay 4NO 220-230V

Product Description

The SCHNEIDER ELECTRIC CA2KN40M7 is a 4-pole normally open (4NO) control relay designed for AC control circuits operating at 220-230 volts, 50/60 Hz. This relay is used to switch and route control signals within motor control panels, HVAC equipment, and industrial automation systems. It carries a compact footprint, measuring 2.6 inches in height, 2.4 inches in width, and 1.9 inches in length, making it suitable for installation in tight enclosures and control panels. Licensed electricians and HVAC controls technicians are the primary installers for this class of relay.

The CA2KN40M7 is suited for use in light-duty control circuit applications across residential, commercial, and light industrial settings. Typical installations include motor starters, contactor auxiliary control circuits, and HVAC control panels where AC coil voltage at 220-230 volts is the standard control voltage. It is packaged as a single unit and is intended as a direct replacement or new-installation component in control panel assemblies requiring a 4NO contact configuration.

Key Features

• 4 normally open (4NO) contact configuration for flexible control circuit switching
• AC coil rated at 220-230 volts, 50/60 Hz for broad international and domestic application
• Compact body: 2.6 inches H x 2.4 inches W x 1.9 inches L for panel space efficiency
• Lightweight at 0.4 pounds, minimizing panel load
• Single-unit packaging with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or direct-fit control relay for AC control circuit applications requiring a 4NO contact arrangement and a 220-230 VAC coil voltage at 50/60 Hz.

Installation Notes

Installation should be performed by a qualified electrician or licensed HVAC controls technician in accordance with NEC guidelines and applicable local codes. De-energize and lock out the control panel before removing the existing relay or installing this unit. Verify coil voltage and contact configuration against the panel schematic before making any wiring connections. Do not apply DC voltage to this AC-rated coil.
