OTM800E4M230C ABB 800 A 4-Pole Motorised Switch Disconnector

Why Choose the ABB OTM800E4M230C 800 A 4-Pole Motorised Switch Disconnector?

The ABB OTM800E4M230C, order code 1SCA115356R1001, is a heavy-duty 800 A 4-pole motorised switch disconnector designed for remote and automated switching of high-current low-voltage electrical circuits. Part of ABB's OTM motorised switch-disconnector range, it combines proven OT switching technology with an integrated motor operator for dependable electrical isolation and control.

The OTM800E4M230C provides an 800 A AC-23A operational current rating at up to 690 V AC and a main-circuit rated operational voltage of up to 1000 V AC. Its four-pole construction switches all four poles simultaneously, making it particularly suitable for three-phase distribution systems where the neutral conductor also requires switching.

A 220–240 V AC motor operating supply enables remote electrical operation from a suitable control system, while manual operation remains available when required. ABB supplies the switch with the appropriate manual handle and shaft kit, terminal bolt hardware, control-circuit connectors and storage clip, providing a comprehensive solution for switchboards, power distribution and industrial automation.

Motorised High-Current Switching and Isolation

Motorised switch disconnectors allow substantial electrical loads to be switched from a remote control system while retaining the isolation functionality of a conventional switch disconnector. The ABB OTM800E4M230C combines an 800 A 4-pole switching unit with a 220–240 V AC motor operator, making it suitable for installations where high-current circuits need to be controlled without routine manual operation at the switch itself.

Its 800 A AC-23A capability at up to 690 V AC, 20 kA short-time withstand rating for 1 s and four-pole simultaneous switching make the OTM800E4M230C particularly suitable for demanding industrial and commercial distribution systems. Manual operating equipment is also supplied, providing a practical local operating method for commissioning, servicing and appropriate maintenance procedures.

Typical Applications

• High-current industrial low-voltage switchboards.
• Remote switching and isolation of three-phase circuits.
• Four-pole distribution systems requiring neutral switching.
• Automated power-distribution systems.
• Industrial machinery and process installations.
• Commercial and infrastructure electrical distribution.
• Building-services power systems.
• OEM switchgear and automation panels requiring motorised isolation.
