3VA9137-0FK37

What type of component is this?

This is a door mounted rotary operator for use with compatible Siemens SENTRON moulded case circuit breaker assemblies. It enables manual operation of the breaker from the outside of an enclosure door.

What is the main application of this rotary operator?

It is typically used on electrical panels where the breaker handle needs to be operated from the enclosure door, helping provide clear external switching control without opening the panel.

Which breaker frame is it intended for?

The unit is specified for use with Siemens 3VA4/5 125 devices, making it suitable for matching 3VA moulded case circuit breaker installations.

Does it include an emergency-off function?

Yes. The product description identifies it as a door mounted rotary operator with emergency-off functionality.

Does this version include a door interlock?

Yes. The 3VA9137-0FK37 version includes a door interlock, which is intended to coordinate the rotary mechanism with the enclosure door arrangement.

What enclosure ratings are associated with this item?

The operator is listed with NEMA type 1, 3R, 12 and 4/4X ratings, making it suitable for a range of indoor and demanding enclosure environments when correctly installed.

What IP rating does it have?

The datasheet lists the protection class as IP65, indicating dust-tight protection and resistance to water jets when installed as specified.

Does it have an integrated lighting feature?

Yes. This variant includes a 24 V DC lighting kit, which helps improve visibility of the operator status or handle area depending on the panel design.

What are the approximate dimensions?

The listed mechanical dimensions are 70 mm in height and 77 mm in width.

How much does it weigh?

The net weight is listed as approximately 569 g.

What accessory category does it fall under?

It is categorised as a Siemens SENTRON accessory, specifically a door-coupling rotary operating mechanism.

What does the door open position accessory refer to?

The door open position accessory is part of the operator assembly configuration and is intended to interact with the door-mounted operating arrangement in compatible panel builds.

Is it suitable for use on enclosure doors rather than directly on the breaker?

Yes. This is a door mounted rotary operator, so it is designed for external operation through an enclosure door rather than only direct operation at the breaker face.

What kind of electrical installations commonly use this component?

It is commonly used in industrial control panels, distribution boards and machinery enclosures where a compatible Siemens 3VA breaker needs external rotary control.
