Available at ARP Impex – Trusted Exporter of Legrand DMX³-I Series Trip-Free Isolator Switches

The Legrand 028788, from the high-performance DMX³-I 4000 series, is a 4000A, 3-pole draw-out type Trip-Free Switch designed to deliver safe, manual disconnection of electrical power in large-scale low-voltage distribution systems. This switch functions purely as an isolator, with no internal protection unit, making it ideal for integration with external protection systems such as circuit breakers.

Engineered with a trip-free mechanism, the switch will disconnect even under fault conditions, even if the operating handle is forcibly kept in the ON position, ensuring enhanced operator safety. The draw-out design offers the flexibility to easily remove the device for inspection or servicing, without disturbing fixed wiring connections.
