D23MR30A - Cutler-Hammer Relay

The Cutler Hammer D23MR30A Type M Relay is a 3-pole control relay designed for use in industrial and commercial electrical systems where reliable switching and control functions are essential to day-to-day operations. Rated for 10 amps and up to 300 volts AC, this relay features a 120 VAC, 60 Hz coil and a reversible contact design, making it a practical solution for maintaining compatible control equipment already in service.

In many facilities, control relays are a critical part of motor control systems, machinery, and automation circuits. When a relay reaches the end of its service life, finding the correct replacement can help minimize downtime and keep equipment operating as intended. The D23MR30A is designed to fit compatible applications that require a Type M relay, allowing maintenance personnel and electricians to restore control functions without making major changes to existing systems.

Whether you're servicing manufacturing equipment, troubleshooting a control circuit, or replacing a worn relay during scheduled maintenance, the D23MR30A provides the form, fit, and function needed for compatible installations.

This relay is commonly found in industrial control panels, motor control assemblies, and other electrical systems where dependable contact operation is required. Built to last and designed for long-term use, the D23MR30A continues to be a practical choice for maintaining existing equipment and preserving original system configurations. The relay may also be associated with catalog numbers D23MB, D26MPR, D26MPL, and D26MPS, which may appear on equipment labels or maintenance documentation.
