1SCA162738R1001 ABB OTC80G2-4BS OT Plus Panel Mounted Switch Disconnector
ABB OTC80G2-4BS 80 A 4-pole I-0-II manual change-over switch with DIN rail or base mounting and a padlockable direct-mounted handle.
Why Choose the ABB 1SCA162738R1001 OTC80G2-4BS Change-Over Switch?
The ABB 1SCA162738R1001, also known as the OTC80G2-4BS, is a robust 80 A 4-pole manual change-over switch designed for reliable transfer between two independent electrical power sources. Part of the ABB OT Plus change-over switch range, it is suitable for mains-to-generator transfer, industrial distribution systems, commercial installations, control panels and OEM machinery.
The OTC80G2-4BS features a front-operated I-0-II switching mechanism and can be installed using either base mounting or DIN rail mounting. Its four-pole configuration enables simultaneous switching of three phases and neutral, making it particularly suitable for applications requiring complete separation between normal and standby supplies.
Integrated screw terminals help simplify wiring, while the supplied direct-mounted knob handle can be padlocked to support safe isolation and lockout procedures. An optional operating shaft may also be installed for external operation through an enclosure door.

Reliable Manual Power Source Transfer
The ABB OTC80G2-4BS enables an electrical load to be transferred manually between two separate supplies, such as a utility mains source and a standby generator. Its defined I-0-II operating sequence provides an intermediate OFF position to help prevent unintended connection between the two power sources.
The four-pole design switches the neutral conductor together with all three phases. This makes the unit suitable for installations where complete source separation, neutral switching or compliance with the electrical system design is required.
Typical Applications
- Mains-to-generator change-over panels.
- Standby power systems.
- Industrial distribution boards.
- Commercial building services.
- OEM machinery and control panels.
- Temporary and alternative power installations.
