£42.97
The ABB 1SCA163483R1001, also known as the OT40G1-3DS, is a high-performance 40 A three-pole switch disconnector designed for the safe isolation of low-voltage electrical circuits in industrial, commercial and OEM applications. Part of the trusted ABB OT Plus switch disconnector range, it combines dependable switching performance with a compact G1 frame, making it ideal for modern control panels and distribution systems.
This model is a front-operated, door-mounted switch disconnector featuring integrated screw terminals. It is designed for installations requiring a 45 mm door cut-out and is operated using a compatible external handle and shaft, which are supplied separately. The protected IP20 front terminals improve installation safety while maintaining reliable electrical performance.
With a rated operational current of 40 A, a three-pole configuration and suitability for voltages up to 690 V AC (IEC), the OT40G1-3DS is ideal for isolating three-phase circuits in machinery, switchboards and industrial electrical installations.
The ABB OT40G1-3DS provides safe manual isolation of three-phase electrical circuits during maintenance, servicing and equipment shutdown. Its door-mounted operating mechanism allows switching from outside the enclosure while live components remain safely enclosed, improving both operator safety and equipment protection.
Engineered for demanding industrial environments, ABB OT Plus switch disconnectors are widely specified by panel builders, OEMs and electrical contractors thanks to their compact construction, robust performance and long operational life.
