125A MAINS-GENERATOR switch, without handle and shaft OT125F3C 1SCA105037R1001

Power switch for demanding applications

This three-pole OT125F3C power switch from ABB is a reliable solution for disconnecting electrical circuits. Designed with safety and functionality in mind, it is perfect for both industrial and commercial installations. Its solid construction and high operating parameters guarantee long-lasting and trouble-free operation.

This switch, with a rated current of 125A, allows for safe switching of loads up to 45 kW at 400V (AC-23). Plug-in design and the possibility of mounting on a DIN rail or plate provide great flexibility during installation. The lack of a handle and roller allows for compact placement in a distribution board, saving valuable space.

Functionality and application

The OT125F3C switch functions as a main disconnect and a maintenance disconnect, providing effective circuit isolation during maintenance work. The rated continuous current of 125A (AC-21) and the ability to withstand short-circuit currents up to 2.5 kA guarantee protection of the installation against overloads and short circuits. The locking mechanism provides additional safety, preventing accidental switching on or off of the circuit.

Thanks to the screw connection of the main contacts, installation is simple and intuitive – both for professional installers and people with electrical experience. The IP20 degree of protection prevents accidental contact, increasing safety.
