Product Description

This Electroswitch Series 24 rotary lockout relay is identified by MPN 78PZ28LA and is rated 250 VDC on its factory label. Lockout relays of this type are used in substation and switchgear protection circuits, where a rotary contact stack holds a breaker in a tripped state until manually reset. The unit shown here uses a multi deck rotary contact assembly with screw terminal connections and a wiring harness intact from the original installation. It is listed as Open Box Unused. Buyers matching an exact Electroswitch catalog number for spare inventory, panel replacement, or maintenance stock can use the MPN and the visible terminal configuration to confirm fit against their own equipment.
