OTM125F4M230V ABB 125 A 4-Pole 230 V Motorised Switch-Disconnector

Why Choose the ABB OTM125F4M230V Motorised Switch-Disconnector?

The ABB OTM125F4M230V is a compact and reliable 125 A four-pole motorised switch-disconnector designed for remote and manual switching and isolation in low-voltage electrical distribution systems. As part of the ABB OTM motorised switch-disconnector range, it combines dependable ABB OT switching technology with an integrated motor operator for automated control applications.

The OTM125F4M230V provides four-pole switching for three-phase systems where the neutral conductor also needs to be disconnected. Its motorised mechanism enables remote operation from control, automation or power-management equipment, while the included handle provides manual operation when local switching is required.

With a rated current of 125 A, four-pole construction and a 230 V motorised operating system, the OTM125F4M230V is well suited to distribution boards, industrial control systems and automated isolation applications. ABB specifies an AC-22A rating of 125 A up to 690 V AC, with AC-23A ratings of 90 A at 415 V and 50 A at 690 V.

Reliable Motorised Isolation for Electrical Distribution

Motorised switch-disconnectors allow electrical circuits to be switched and isolated remotely, making them particularly useful in automated distribution systems and installations where switching commands originate from control equipment. Manual operation remains available for commissioning, maintenance and local control.

The ABB OTM125F4M230V combines motorised operation with a compact four-pole switch-disconnector architecture. Its ability to switch all three phases together with the neutral makes it suitable for applications requiring complete four-pole isolation, while its AC-22A and AC-23A ratings support a broad range of industrial and commercial electrical loads.

Typical Applications

• Low-voltage distribution boards.
• Industrial electrical control panels.
• Remote-controlled electrical isolation.
• Automated power distribution systems.
• Three-phase and neutral switching applications.
• Building services and infrastructure equipment.
• OEM machinery and electrical assemblies.
