OTM2500E4M230C ABB 2500 A 4-Pole Motorised Switch-Disconnector

Why Choose the ABB OTM2500E4M230C Motorised Switch-Disconnector?

The ABB OTM2500E4M230C is a heavy-duty 2500 A four-pole motorised switch-disconnector designed for remote switching and dependable electrical isolation in high-current low-voltage power distribution systems. As part of the ABB OTM motor-operated switch-disconnector range, it combines robust OT switching technology with an integrated motor operator for demanding industrial and infrastructure applications.

The OTM2500E4M230C provides four-pole switching, making it suitable for installations where all three phase conductors and the neutral must be switched together. Its motorised operating mechanism enables remote control from automation, power-management and supervisory systems, while the supplied manual operating handle allows local operation when required.

With a rated current of 2500 A, a maximum rated operational voltage of 1000 V AC and a 230 V-class motor operator, the OTM2500E4M230C is engineered for high-capacity electrical distribution. The complete assembly is base mounted and includes the manual operating handle, terminal bolt kit, control-circuit connectors and handle and spare-fuse storage clip.

Reliable Motorised Isolation for High-Current Power Systems

Motorised switch-disconnectors allow high-current electrical circuits to be switched remotely while retaining a means of positive electrical isolation. They are particularly useful in large distribution systems where switching commands originate from automation equipment, building-management systems or central power-control platforms.

The ABB OTM2500E4M230C combines a 2500 A switching platform with four-pole construction and motorised operation, providing a practical solution for large switchboards and power distribution assemblies. Manual operation remains available for commissioning, maintenance and local control, giving operators flexibility when managing critical electrical infrastructure.

Typical Applications

• Main low-voltage distribution switchboards.
• High-current industrial power distribution.
• Automated electrical isolation systems.
• Commercial and infrastructure power installations.
• Data centre and critical-power distribution.
• Large manufacturing and process facilities.
• OEM switchgear and power distribution assemblies.
