OT315ES40K ABB 315 A 4-Pole Side-Operated Switch-Disconnector with Direct-Mounted Handle

Why Choose the ABB OT315ES40K Switch-Disconnector?

The ABB OT315ES40K is a heavy-duty 315 A four-pole side-operated switch-disconnector designed for dependable switching and electrical isolation in industrial power distribution, machinery and switchboard applications. Part of the established ABB OT switch-disconnector series, it provides coordinated four-pole switching for demanding low-voltage electrical systems.

This model features side operation with the operating mechanism positioned on the right and is supplied with a direct-mounted handle. This arrangement is particularly useful where switchboard geometry, conductor routing or accessibility favours local operation from the right-hand side of the switching device.

The OT315ES40K has an open-air thermal current rating of 315 A and provides 315 A AC-22A and 315 A AC-23A operational current at 400–415 V. Its four-pole configuration, robust OT315 platform and direct handle arrangement make it a practical solution for high-current industrial isolation.

Key Advantages

• Heavy-duty 315 A switch-disconnector for industrial switching and isolation.

Right-Side Direct Operation for Four-Pole Isolation

The OT315ES40K combines 315 A four-pole switching with a right-side operating mechanism and direct-mounted handle. Side operation can simplify equipment layouts where front access is restricted or where the position of busbars and conductors makes lateral operation preferable.

All four poles operate together, enabling coordinated isolation of four conductors from a single mechanism. This makes the OT315ES40K particularly suitable for industrial distribution systems requiring four-pole switching, including applications where the neutral conductor is required to be disconnected together with the three phases.

Typical Applications

• Industrial four-pole power distribution.
• Three-phase systems requiring switched-neutral isolation.
• Machine and production-equipment isolation.
• Side-operated electrical control panels.
• Industrial switchboards and distribution assemblies.
• OEM machinery and automation systems.
