OT315ES30K ABB 315A 3-Pole Right-Side Operated Switch-Disconnector

Why Choose the ABB OT315ES30K 315A 3-Pole Side-Operated Switch-Disconnector?

The ABB OT315ES30K is a heavy-duty 315 A three-pole switch-disconnector designed for dependable load switching and electrical isolation in industrial low-voltage power systems. Part of the ABB OT switch-disconnector range, this model combines high-current switching capability with a side-operated arrangement for installations where access from the right-hand side of the switch is required.

The OT315ES30K features a side-operated mechanism positioned on the right and is supplied with a direct-mounted operating handle. This arrangement provides convenient local ON/OFF operation without requiring a conventional door-coupled shaft-and-handle assembly, while base mounting supports integration into industrial switchboards, control panels and machinery.

Rated at 315 A, the OT315ES30K provides 315 A AC-21A, AC-22A and AC-23A switching capability at 380–690 V AC. It has a rated operational voltage of 1000 V, a rated insulation voltage of 1000 V, a 12 kV impulse withstand voltage and a 15 kA for 1 s short-time withstand current for demanding industrial applications.

High-Performance Right-Side Switching and Isolation

Switch-disconnectors provide a defined means of manually switching electrical loads and establishing circuit isolation for operation, servicing and maintenance. The side-operated construction of the ABB OT315ES30K is particularly useful where panel or machinery layouts favour access from the side rather than a conventional front-operated shaft arrangement.

The OT315ES30K combines a 315 A current rating, three-pole construction, right-side mechanism and direct-mounted handle with strong AC-23A performance. Its 15 kA for 1 s short-time withstand rating and operation at voltages up to 1000 V make it a robust isolation solution for demanding industrial electrical systems.

Typical Applications

• Industrial machinery main-switch and isolation applications.
• Three-phase low-voltage power-distribution systems.
• Industrial switchboards and control panels.
• Installations requiring right-side direct operation.
• Manufacturing and process-industry equipment.
• High-current local switching and maintenance isolation.
