ABB OTC60G3-4BS 60 A four-pole manual change-over switch with I-0-II operation, base and DIN-rail mounting, padlockable handle and screw terminals for industrial power transfer applications.
The ABB OTC60G3-4BS, product code 1SCA162742R1001, is a high-quality four-pole manual change-over switch engineered for dependable switching between two independent power sources. As part of the trusted ABB OT Plus change-over switch range, it provides reliable I-0-II operation for industrial electrical distribution, machinery and standby power applications.
Designed for panel builders and industrial electrical engineers, this compact front-operated switch features a base-mounted construction with DIN-rail mounting capability for straightforward installation. Integrated screw terminals provide secure electrical connections, while the supplied padlockable direct-mounted handle helps improve operational safety during maintenance.
With a rated current of 60 A, a four-pole switching configuration and support for operating voltages up to 600 V AC under UL ratings, the OTC60G3-4BS is ideally suited to transferring loads between mains and backup power supplies whilst providing reliable electrical isolation.
Manual change-over switches safely transfer electrical loads between two independent power sources while ensuring complete isolation through the centre OFF position. Four-pole models also switch the neutral conductor, making them particularly suitable for generator installations and systems requiring complete circuit isolation.
The ABB OTC60G3-4BS provides dependable mechanical performance, compact installation and long service life, making it an excellent choice for electrical distribution systems, control panels and industrial switchgear where reliable manual source selection is essential.
