OT630E04K ABB 630 A 4-Pole Switch-Disconnector with Direct-Mount Handle

Why Choose the ABB OT630E04K 630 A 4-Pole Switch-Disconnector?

The ABB OT630E04K is a heavy-duty 630 A, 4-pole switch-disconnector designed for dependable manual switching and electrical isolation in demanding low-voltage installations. Part of ABB's established OT range, it combines high-current switching capability with a compact base-mounted design for industrial switchboards, machinery and power distribution systems.

The OT630E04K is a front-operated switch-disconnector with the operating mechanism at the left-hand end of the switch. Its four-pole arrangement provides simultaneous switching of the fourth pole, while its IEC ratings include 630 A AC-21A, AC-22A and AC-23A at 380–415 V AC.

A key feature of this K variant is its direct-mounted operating arrangement. The switch is supplied with an ABB OTV800EK black Test-OFF-ON direct-mount pistol handle, operating shaft and M12 × 40 terminal bolt kit as standard, providing a practical complete operating package for suitable panel and switchboard installations.

Reliable Direct-Mount Switching and Isolation

The ABB OT630E04K provides a robust means of manually switching and isolating high-current electrical circuits. Its 630 A, four-pole configuration supports simultaneous isolation of four conductors, while its 630 A AC-23A rating at 380–415 V AC makes it suitable for demanding industrial load-switching applications.

The included OTV800EK direct-mounted pistol handle allows operation directly at the switch and can be padlocked in the OFF position to support maintenance-isolation procedures. Combined with the supplied shaft and M12 × 40 terminal bolt kit, the OT630E04K provides a practical configuration for industrial switchboards, machinery and electrical control systems.

Typical Applications

• High-current industrial power distribution systems.
• Four-pole electrical switching and isolation.
• Industrial switchboards and distribution assemblies.
• Machinery and production equipment.
• Electrical control systems.
• Motor and inductive-load switching applications.
• Maintenance isolation requiring a direct-mounted, padlockable operating handle.
