Reliable 500 A Four-Pole Electrical Isolation

Switch-disconnectors provide a defined means of manually separating electrical equipment from its power source. This allows downstream circuits, machinery and distribution equipment to be isolated during maintenance, servicing and planned shutdown procedures while providing a clear switching function within the electrical installation.

The ABB OT range is engineered for demanding industrial applications where reliable switching performance and compact installation are important. The OT500E22P combines a 500 A current rating with four-pole switching and front operation, making it a practical choice for high-current distribution systems and industrial equipment isolation.

Typical Applications

• Industrial electrical distribution switchboards.
• Three-phase and neutral circuit isolation.
• Main and sub-distribution systems.
• Industrial machinery disconnect applications.
• Control panels and power distribution assemblies.
