Schneider Electric CA2KN22U7 Control Relay 2NC 2NO 230-240V

Product Description

The SCHNEIDER ELECTRIC CA2KN22U7 is a control relay designed for industrial and commercial electrical control circuits. It features a 2NC/2NO contact configuration, giving technicians two normally closed and two normally open contacts in a single compact device. The coil operates on 230-240 VAC at 50/60 Hz, making it compatible with standard single-phase AC control voltage across North American and international 50 Hz installations. Weighing 0.39 pounds, this relay is a direct replacement or service part suited for panel builders, electricians, and automation technicians maintaining control logic circuits.

This relay is applied in motor control centers, machine control panels, HVAC control circuits, and other industrial automation environments where switching of low-power control signals is required. Its dual-coil-frequency rating allows installation in facilities running either 50 Hz or 60 Hz supply systems. The compact footprint makes it a practical fit in densely wired enclosures where space is limited. Licensed electricians and panel technicians are the primary installers in commercial and light industrial settings.
