Why Choose the IMO BIS3125A 125 A 3-Pole Isolating Switch?

The IMO BIS3125A is a high-current 3-pole isolating switch designed to provide reliable electrical isolation in industrial, commercial and control-panel applications. Manufactured by IMO Precision Controls, it enables three circuit conductors to be switched simultaneously, providing a practical means of disconnecting three-phase equipment and circuits from the main electrical supply.

Rated at 125 A and 230/400 V AC, the BIS3125A combines substantial current capacity with a modular 3-module design. Its DIN rail mounting makes it suitable for integration into distribution boards, industrial machinery panels and electrical control enclosures where dependable three-pole isolation is required.

The BIS3125A forms part of IMO's modular isolating switch disconnector range and is manufactured in accordance with IEC 60947-3. It accepts conductors up to 35 mm² and is compatible with standard IMO MCB accessories, providing panel builders and electrical engineers with a flexible high-current isolation solution.

  • Designed for electrical switching, disconnection and circuit isolation.
  • Compatible with standard IMO modular MCB accessories.

High-Current Three-Pole Isolation for Electrical Systems

A three-pole isolating switch provides a convenient means of disconnecting all three conductors of a three-phase circuit together. This makes the BIS3125A particularly useful for machinery, distribution equipment and industrial electrical systems where a clearly defined isolation point is required for servicing, maintenance or operational procedures.

The IMO BIS3125A is intended primarily for switching and electrical isolation rather than automatic overload or short-circuit protection. With its 125 A rating, 230/400 V AC capability, three-pole configuration and IEC 60947-3 construction, it provides a practical high-current isolation solution for professional low-voltage installations.

Typical Applications

  • Three-phase electrical distribution boards.
  • Industrial machinery isolation.
  • Control-panel incoming supply isolation.
  • Commercial and industrial electrical installations.
  • Automation and manufacturing equipment.
  • Maintenance and service isolation points.
