Eaton Cutler-hammer D26MR40A Relay Latch Attachment 600V

Product Description

The EATON CUTLER-HAMMER D26MR40A is a relay latch attachment rated for 600 volts AC, designed to add mechanical latching functionality to compatible multipole relay assemblies. This accessory locks a relay in the energized or de-energized position without requiring continuous coil power, reducing energy draw and heat in control panel applications. It is installed by licensed electricians and industrial control technicians working on motor control centers, switchgear, and machine control panels where maintained-contact operation is required.

The D26MR40A is suited for use in industrial and commercial electrical control systems where relay state must be held independent of coil voltage. Typical installation scenarios include machine tool controls, process automation panels, and motor starter assemblies. It is designed specifically for use with the D26 Multipole Relay series, making it a direct accessory for existing D26-equipped panels and enclosures.
