OT315E03WP ABB 315 A 3-Pole Wide Phase Switch-Disconnector

Why Choose the ABB OT315E03WP Switch-Disconnector?

The ABB OT315E03WP is a high-performance 315 A three-pole switch-disconnector with wide phase distance, 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 increased phase spacing for demanding low-voltage installations.

This model is front operated and base mounted, with phase barriers fitted as standard. It is supplied with an OHB95J12 black ON-OFF pistol handle and OXP12X185 operating shaft. The handle provides IP65 protection, is padlockable in the OFF position and supports door interlocking for secure operation and maintenance isolation.

The OT315E03WP has an open-air thermal current rating of 315 A and delivers 315 A AC-22A and 315 A AC-23A performance at 400–415 V. With a 180 kW AC-23A rating at 400–415 V, 1000 V rated operational voltage and robust short-circuit withstand characteristics, it is well suited to demanding industrial switching applications.

Wide Phase Distance for High-Current Isolation

The OT315E03WP combines ABB's proven OT switching mechanism with a wide phase-distance configuration and factory-fitted phase barriers. This arrangement provides increased physical separation between phases while maintaining simultaneous three-pole operation, making the switch well suited to demanding switchboard and industrial power-distribution designs.

The supplied OHB95J12 handle and OXP12X185 shaft provide enclosure-door operation, while the handle's IP65 protection, OFF-position padlocking and door-interlocking functionality support controlled electrical isolation. A 15 kA one-second short-time withstand current and 65 kA short-circuit making capacity at 690 V further support use in robust industrial installations.
