Description
The ABB OT40F3P Front Operated Non-Fusible Disconnect Switch is a three-pole disconnect switch designed for industrial power distribution, motor control, and electrical isolation applications. Rated at 40 A and 600 V AC, it supports three-phase motor applications up to 25 hp at 600 V and provides a reliable means of manually disconnecting electrical circuits.
Part of ABB’s OT Series, the OT40F3P features a compact, modular design with base and DIN-rail mounting compatibility for integration into industrial control panels. Its finger-proof, dead-front construction and protected terminals help reduce the risk of accidental contact with live electrical components. The switch features a quick-make, quick-break operating mechanism, welded contact protection, and clear position markings for dependable operation.
The OT40F3P is supplied with an OHB65J6 pistol handle and OXP6X170 operating shaft for front operation. The handle supports padlocking in the OFF position with up to three padlocks, while the operating mechanism provides door interlocking to help prevent the enclosure from opening while the switch is ON. Incoming power can be connected from either the top or bottom, providing flexibility during installation.
