Why Choose the ABB OT2000EM04P 2000 A 4-Pole Earthing Switch?
The ABB OT2000EM04P is a heavy-duty 2000 A 4-pole earthing switch designed for high-current industrial electrical installations. Part of ABB's high-performance OT range, this EM configuration provides a dedicated earthing function for applications where circuits or equipment must be securely connected to earth as part of an electrical isolation and maintenance arrangement.
The OT2000EM04P is a front-operated, bottom-mounted earthing switch supplied complete with a black OFF–earth operating handle, shaft and terminal bolt kit. The handle is padlockable in both the OFF and earth positions, supporting controlled switching and secure maintenance procedures.
Designed for demanding high-current systems, the OT2000EM04P provides a rated short-time withstand current of 55 kA for 1 s, 80 kA for 0.25 s and a 176 kA peak short-circuit making capacity. Its four-pole configuration and robust construction make it suitable for substantial industrial switchboards and power distribution assemblies.

High-Current Earthing for Industrial Power Systems
The ABB OT2000EM04P provides a robust four-pole earthing function for high-current industrial installations where equipment must be intentionally connected to earth as part of safe isolation and maintenance procedures. Its 55 kA withstand capability for 1 s and 176 kA peak making capacity provide substantial short-circuit performance for demanding electrical systems.
The front-operated, bottom-mounted EM configuration is supplied with the required OFF–earth handle, shaft and terminal bolt kit. Padlocking in both operating positions supports controlled access and maintenance procedures, while the four-pole arrangement makes the switch suitable for installations requiring simultaneous earthing across four conductors.
Typical Applications
- High-current industrial earthing systems.
- Main low-voltage switchboards.
- Electrical isolation and maintenance arrangements.
- Industrial power distribution assemblies.
- Manufacturing and process installations.
- Heavy-duty switchgear and electrical panel systems.
