Why Choose the IMO C4/63R-EH1-315 Door-Coupling Rotary Mechanism?
The IMO C4/63R-EH1-315 is a robust black door-coupling rotary mechanism designed for external operation of IMO C4/63R motor circuit breakers installed inside electrical enclosures. It enables the circuit breaker to be operated from the front of a cabinet or control-panel door, providing convenient ON/OFF control while the protective device remains enclosed.
As part of the IMO C4 motor circuit breaker accessory range, the C4/63R-EH1-315 incorporates a door-locking mechanism that helps prevent accidental opening of the cubicle door while the circuit breaker is in the ON position. The OFF position can also be secured with up to three padlocks, providing a practical means of controlling access during electrical maintenance and isolation procedures.
The mechanism features a black external handle and a long 315 mm extension shaft, making it particularly suitable for applications requiring greater distance between the enclosure door and the internally mounted circuit breaker. The door-coupling rotary mechanism provides an IP65 protection rating for demanding industrial control-panel applications.
Key Advantages
- Purpose-designed door-coupling rotary mechanism for IMO C4/63R motor circuit breakers.
- Long 315 mm extension shaft for deeper electrical enclosures.
- Black external rotary handle for convenient circuit breaker operation.
- IP65 protection rating for industrial control-panel applications.
- Door-locking mechanism helps prevent accidental opening while the circuit breaker is ON.
- OFF position can be secured with up to three padlocks.
Key Features
- IMO C4 motor circuit breaker accessory.
- Black door-coupling rotary mechanism.
- 315 mm extension shaft.
- Designed specifically for IMO C4/63R motor circuit breakers.
- IP65 rated door-coupling rotary mechanism.
- Integrated door-locking function in the ON position.
- OFF-position locking facility for up to three padlocks.
- External operation of an internally mounted motor circuit breaker.
Reliable External Motor Circuit Breaker Operation
Door-coupling rotary mechanisms allow motor circuit breakers mounted inside electrical cabinets to be operated from outside the enclosure. The external handle is mechanically coupled to the circuit breaker through an extension shaft, allowing normal ON/OFF operation without requiring the operator to open the cabinet.
The IMO C4/63R-EH1-315 combines this external operating capability with door interlocking and padlocking functions. Its extended 315 mm shaft makes it suitable for deeper panel configurations, while the IP65-rated mechanism supports use in demanding industrial environments where protection against dust and water ingress is important.
Typical Applications
- Industrial motor control panels.
- Deep electrical control cabinets and enclosures.
- Motor starter assemblies.
- Industrial machinery and automation equipment.
- Pump, fan and conveyor control systems.
- OEM machinery and electrical panel building.
