Why Choose the ABB OT1250E04 Switch Disconnector?
The ABB OT1250E04 is a heavy-duty 1250 A four-pole switch disconnector designed for dependable switching and electrical isolation in high-current industrial power distribution systems. As part of the ABB OT switch-disconnector series, it provides robust manual isolation for switchboards, distribution panels and demanding low-voltage installations.
This switch disconnector is front operated and base mounted, providing a practical arrangement for integration into electrical panels and switchgear assemblies. Its four-pole construction enables simultaneous isolation of four conductors, making it suitable for three-phase systems where neutral switching is required.
With a rated current of 1250 A, a maximum rated operational voltage of 1000 V AC and a rated short-time withstand current of 50 kA for 1 s, the OT1250E04 is engineered for demanding industrial distribution duties. The switch is supplied without an operating handle and shaft, allowing suitable operating accessories to be selected separately, while the terminal bolt kit is included.

Reliable High-Current Switching and Isolation
Switch disconnectors provide manual load switching together with dependable electrical isolation, allowing circuits and equipment to be disconnected from their power source during maintenance, servicing and operational procedures. High-current industrial installations require robust switching devices capable of carrying substantial continuous loads while maintaining reliable isolation performance.
The ABB OT1250E04 combines a 1250 A current rating with four-pole switching, high short-circuit withstand capability and a compact base-mounted design. Its separately selected handle and shaft arrangement also provides flexibility when configuring the switch for different switchboard and enclosure layouts.
Typical Applications
- Industrial low-voltage switchboards.
- High-current electrical distribution systems.
- Main and local electrical isolation.
- Three-phase systems requiring four-pole switching.
- Manufacturing and process plant switchgear.
- Power distribution panels and industrial control assemblies.
