The BG CPRSD425-01 25A four-pole rotary isolator switch provides safe and clearly visible local isolation for suitable three-phase electrical equipment. Its four-pole configuration can disconnect three phases and neutral together, making it suitable for compatible motors, pumps, HVAC systems, machinery and other commercial or light-industrial electrical equipment.

Designed for demanding indoor and outdoor locations, the isolator is housed inside a light-grey insulated enclosure with an IP65 weatherproof rating. When correctly installed, the enclosure protects the internal switch against dust and water jets, making it suitable for workshops, plant rooms, warehouses, agricultural buildings and external equipment installations.

The highly visible red and yellow rotary handle provides clear ON, OFF and locked-position indication. It can be secured in the OFF position with a suitable padlock, helping prevent accidental or unauthorised reconnection while connected equipment is being inspected, serviced or maintained.

For additional safety, the switching mechanism is mechanically interlocked with the enclosure lid. This prevents the cover from being opened while the isolator is in the ON position. Captive retained cover screws and captive backed-out terminal screws also help simplify installation and reduce the risk of components being misplaced.

Four M20/25 cable-entry knockouts, with two positioned at the top and two at the bottom, provide flexible cable-routing options. Earth terminals are included, while BG’s available technical data lists a conductor capacity of 6mm² to 10mm² for the CPRSD425 model.

Rated at 25A, the isolator supports 230V and 400V AC operation. BG’s four-pole technical sheet lists three-phase motor ratings of 5.5kW at 230V and 7.5kW at 400V. The product is manufactured and tested to BS EN 60947-3 and is covered by BG Electrical’s ten-year warranty.

The BG CPRSD425-01 is a strong choice for electricians and contractors searching for a 25A four-pole isolator, three-phase rotary isolator switch, IP65 weatherproof isolator, padlockable industrial switch disconnector, 400V machinery isolator or local isolation switch for pumps, motors and HVAC equipment.
