OT315U04P ABB 315 A 4-Pole UL Switch-Disconnector with Left-Side Mechanism

Why Choose the ABB OT315U04P UL Switch-Disconnector?

The ABB OT315U04P is a heavy-duty 315 A four-pole UL switch-disconnector designed for dependable manual switching and electrical isolation in industrial power distribution, machinery and control-panel applications. Part of ABB's established OT range, it is a non-fusible disconnect solution for installations requiring a high-current four-pole switching device.

This model features a left-positioned operating mechanism and a four-pole configuration for simultaneous isolation of four conductors. The arrangement is particularly useful for three-phase systems where the neutral conductor must be disconnected together with the three phase conductors.

Designed for North American as well as IEC applications, the OT315U04P belongs to ABB's UL switch-disconnector family and is suitable for installations requiring compliance with UL 98, CSA C22.2 No. 4 and IEC 60947-3. Its base-mounted construction allows the operating handle and shaft arrangement to be selected separately to suit the enclosure and installation.

Four-Pole UL Isolation with Left-Side Mechanism

The OT315U04P provides coordinated four-pole isolation at 315 A, allowing four conductors to be disconnected together through a common operating mechanism. This makes the device suitable for three-phase installations where switched-neutral isolation is required as well as other four-conductor distribution arrangements.

Its left-positioned mechanism provides a defined mechanical layout for panel and switchboard designs, while the separately selected handle and shaft give system designers flexibility in matching the operating arrangement to the enclosure depth and installation requirements. As a non-fusible disconnect, the OT315U04P provides switching and isolation while circuit protection is provided separately by the electrical system.

Typical Applications

• Industrial four-pole power distribution.
• Three-phase systems requiring switched-neutral isolation.
• North American industrial control panels.
• Machine and production-equipment disconnects.
• Electrical switchboards and distribution assemblies.
• OEM machinery and industrial automation systems.
