OT315ES03 ABB 315 A 3-Pole Side-Operated Switch-Disconnector

Why Choose the ABB OT315ES03 Side-Operated Switch-Disconnector?

The ABB OT315ES03 is a heavy-duty 315 A three-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 combines high current capacity with a compact side-operated configuration.

This model is designed for side operation and base mounting, providing an alternative to front-operated arrangements where panel layout, busbar positioning or equipment accessibility favours operation from the side. The operating handle must be ordered separately, allowing the appropriate ABB handle arrangement to be selected for the installation.

The OT315ES03 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. ABB supplies an M10 × 30 mm terminal bolt kit as standard, making the switch a practical solution for demanding three-phase industrial isolation duties.

Key Advantages

• Heavy-duty 315 A switch-disconnector for industrial switching and isolation.
• Three-pole configuration for three-phase electrical systems.
• Side-operated design for flexible switchboard and panel layouts.
• Base-mounted construction for integration into electrical assemblies.
• 315 A AC-22A and AC-23A performance at 400–415 V.
• Separate handle selection allows the operating arrangement to be matched to the installation.

Flexible Side-Operated Three-Phase Isolation

Side-operated switch-disconnectors are particularly useful where enclosure geometry, conductor routing or switchboard design makes side access preferable to conventional front operation. The OT315ES03 provides simultaneous three-pole switching from a compact base-mounted assembly, supporting reliable isolation of three-phase industrial circuits.

Unlike the OT315ES03K version with its direct-mounted handle included, the OT315ES03 operating handle is selected separately. This gives panel builders and OEMs greater flexibility when configuring the operating arrangement, while the included M10 × 30 mm terminal bolt kit supports straightforward installation.

Typical Applications

• Industrial three-phase power distribution.
• Machine and production-equipment isolation.
• Side-operated electrical control panels.
• Industrial switchboards and distribution assemblies.
• Manufacturing and process installations.
• OEM machinery and automation systems.
