Product description

The ABB OTC63G2-4BS (1SCA162736R1001) is a 4-pole manual change-over switch from the OT Plus switch-disconnector series, rated 63A at AC-21A/AC-22A (415V and 690V) for switching between two supply sources — typically grid and generator or grid and backup. It's a base-mounted, DIN-rail mountable unit with a front-operated, direct-mounted knob handle that is padlockable, and a shaft that can be extended for external operation. It uses inbuilt screw terminals (up to 35mm² Cu) and accepts up to 2 NO + 2 NC auxiliary contacts, with a switchable fourth pole (simultaneous or late-break/early-make). Rated to 800V insulation with 50kA conditional short-circuit current (80A fuse), 8kV impulse withstand, and Front IP20 protection, it complies with IEC60947-3, UL60947-4-1, and CSA C22.2. Made in Finland.
