ABB VD4 12.06.16 p135 vacuum circuit breaker for medium-voltage switchgear replacement
The ABB VD4 12.06.16 p135 vacuum circuit breaker is a medium-voltage switching device designed for the control and protection of electrical distribution systems. The matching ABB catalogue designation is VD4/P 12.06.16 p135, identified as a 12 kV withdrawable circuit breaker with a rated normal current of 630 A and a rated short-circuit breaking current of 16 kA.
This VD4 configuration can be considered for switchgear maintenance, installed-equipment replacement, retrofit planning and industrial power-distribution projects. Because VD4 circuit breakers may differ in mechanical arrangement, auxiliary circuits and production generation, buyers should verify the complete nameplate and installation details before ordering.

Why this VD4 configuration is used
Vacuum interruption is widely used in medium-voltage distribution because an electrical arc can be extinguished rapidly inside the vacuum interrupter. The ABB VD4 family combines vacuum switching technology with a mechanical operating mechanism for primary distribution applications.
For an existing installation, the ABB VD4 12.06.16 p135 vacuum circuit breaker may provide a model-specific starting point for sourcing a compatible replacement. However, matching only the voltage and current ratings is not sufficient. The complete mechanical and electrical interface must also correspond to the installed switchgear.
Typical application areas
- Medium-voltage power distribution systems
- Industrial plants and manufacturing facilities
- Utility and infrastructure substations
- Commercial building electrical distribution
- Mining, water-treatment and process-industry facilities
- Switchgear maintenance and planned replacement projects
- Retrofit projects requiring a compatible VD4 configuration
Compatibility checks before purchasing
When requesting the ABB VD4 12.06.16 p135 vacuum circuit breaker, provide a clear photograph of the original nameplate whenever possible. The following information helps determine whether the offered unit is suitable for the existing panel:
- Complete ABB type designation and serial information
- Rated voltage, current and short-circuit rating
- Switchgear model and panel configuration
- Closing coil, opening coil and charging-motor voltages
- Secondary plug and auxiliary-contact arrangement
- Truck, shutter and earthing-switch interlocks
- Contact-arm arrangement and mechanical dimensions
- Required accessories and protection functions
- Condition requirement and intended installation environment
These checks are particularly important when the circuit breaker is being sourced for an older installation. Devices with similar front appearances or abbreviated model descriptions may still have different secondary wiring, interlocks or mechanical interfaces.
Buyer-focused identification support
The search description “ABB VD4 12.06.16 p135 vacuum circuit breaker” corresponds to a specific rating combination, but the final supply scope should be established from the nameplate and supporting photographs. Our identification process can compare the requested designation, principal ratings and visible configuration before a quotation is prepared.
For faster technical review, send the nameplate image, front and side photographs, secondary plug details, control voltage and switchgear model with your inquiry. If the original unit is unavailable, provide the project drawing or previous purchase record.
Frequently asked questions
What are the principal ratings of ABB VD4 12.06.16 p135?
The matching ABB catalogue entry identifies the circuit breaker as a 12 kV, 630 A and 16 kA VD4/P withdrawable configuration.
Is this a fixed or withdrawable circuit breaker?
The corresponding ABB catalogue designation, VD4/P 12.06.16 p135, is listed in the withdrawable circuit-breaker selection section. The physical unit and switchgear interface should still be verified before purchase.
Can a circuit breaker with the same electrical ratings be used as a direct replacement?
Not automatically. Electrical ratings are only part of the compatibility assessment. Mechanical dimensions, contact arrangement, interlocks, secondary connections, control voltage and accessories must also match the existing installation.
What information is needed for a quotation?
Please provide the complete model, nameplate photographs, required quantity, switchgear type, control voltage, accessory requirements, delivery destination and desired condition. This information reduces identification errors and supports a more accurate quotation.
