OT1600E30W4 ABB 1600 A 3-Pole Switch Disconnector with 140 mm Phase Distance

Why Choose the ABB OT1600E30W4 Wide Phase Distance Switch Disconnector?

The ABB OT1600E30W4 is a heavy-duty 1600 A three-pole switch disconnector designed for dependable switching and electrical isolation in high-current industrial power distribution systems. Part of the ABB OT switch-disconnector series, it combines substantial current-carrying capability with a wide phase distance configuration for demanding switchboard installations.

This model is front operated and base mounted and features a wide 140 mm phase distance, providing increased spacing between the three phase connections. The configuration is particularly useful in high-current assemblies where conductor layout, busbar arrangements and increased terminal spacing are important design considerations.

The OT1600E30W4 is supplied without an operating handle and shaft, allowing the appropriate ABB operating accessories to be selected separately to suit the enclosure and installation depth. A terminal bolt kit is included for the main-circuit connections.

High-Current Isolation with 140 mm Phase Spacing

Switch disconnectors provide controlled manual switching together with electrical isolation, enabling circuits and equipment to be disconnected from their supply during maintenance, servicing and operational procedures. High-current industrial installations require robust switching equipment capable of integrating effectively with substantial cables, busbars and distribution assemblies.

The ABB OT1600E30W4 combines a 1600 A three-pole configuration with a wide 140 mm phase distance. This increased spacing provides additional room between phase connections and makes the switch particularly suitable for high-current switchboard designs where conductor routing and terminal separation are important.

Typical Applications

• Industrial low-voltage switchboards.
• High-current three-phase distribution systems.
• Main and local electrical isolation.
• Switchboards requiring increased phase spacing.
• Large cable and busbar distribution assemblies.
• Manufacturing and process plant switchgear.
• Industrial power distribution panels.
