Technical Specifications
Additional Technical Notes & Compatibility Information
Operating arrangement: The assembly combines a door-coupling mechanism, extension shaft and front rotary operating mechanism for the corresponding circuit breaker.
Compatibility restriction: This door-coupling operating mechanism is not suitable for VL160X circuit breakers equipped with an RCD module.
Product identification: The 3HF05 is the standard version. It should not be confused with the separately listed emergency-stop variant.
Documentation: Search the exact designation 3VL9300-3HF05 for the Siemens datasheet PDF and related 3VL accessory manual information.
Application & Failure Scenarios
This accessory is used in electrical distribution cabinets and industrial control enclosures where a compatible 3VL circuit breaker is operated through a cabinet door.
Typical replacement search situations:
- Door-mounted rotary operating mechanism is damaged or mechanically worn.
- Cabinet door operation is no longer properly coupled to the circuit breaker.
- The handle or operating assembly is missing or damaged during maintenance.
- Maintenance requires identification of the original door-coupling accessory.
Operational concern: A damaged door operator can prevent normal external operation and complicate maintenance access. Replacement selection should be based on the actual breaker frame and configuration.
