OT1600E04W4P ABB 1600 A 4-Pole Switch Disconnector 140 mm Phase Distance

Why Choose the ABB OT1600E04W4P Wide Phase Distance Switch Disconnector?

The ABB OT1600E04W4P is a heavy-duty 1600 A four-pole switch disconnector designed for reliable switching and electrical isolation in high-current industrial power distribution systems. As part of the ABB OT switch-disconnector series, it combines robust electrical performance with an extended phase spacing configuration for demanding switchboard and power distribution applications.

This switch disconnector is front operated and base mounted, with a wide 140 mm phase distance that provides increased spacing between phase connections. Its four-pole construction provides simultaneous switching of all four poles, while the supplied black IP65 ON-OFF handle and operating shaft provide a complete manual operating arrangement for switchboard installation.

With an open-air thermal current of 1600 A, rated operational currents of 1600 A AC-22A and 1250 A AC-23A at 400–415 V, and a rated short-time withstand current of 50 kA for 1 s, the OT1600E04W4P is engineered for substantial industrial loads. Its wide phase spacing and high electrical ratings make it particularly suitable for high-current distribution assemblies requiring additional separation between conductors.

Reliable High-Current Switching with Wide Phase Spacing

Switch disconnectors provide manual load switching together with dependable electrical isolation, allowing circuits and equipment to be disconnected from their power source for maintenance, servicing and operational procedures. In high-current switchboards, adequate spacing between phase connections can also simplify conductor arrangements and support the design of substantial power distribution assemblies.

The ABB OT1600E04W4P combines a 1600 A thermal current rating with four-pole switching and a wide 140 mm phase distance. Its high short-circuit withstand capability, supplied IP65 handle and adjustable operating shaft make it well suited to demanding industrial switchboards requiring secure manual isolation and increased phase spacing.

Typical Applications

• Industrial low-voltage switchboards.
• High-current electrical distribution systems.
• Installations requiring increased phase spacing.
• Main and local electrical isolation.
