Description

ABB Medium voltage indoor circuit breakers VD4 R Breaker AIS ABB MV Products

VD4 R circuit breaker : Our product offering covers a wide spectrum of technologies across the entire voltage range including indoor and outdoor circuit breakers, air and gas insulated switchgear, instrument transformers, disconnectors, capacitor banks, reactive power compensators, power and distribution transformers and a range of power distribution products like compact secondary substations (CSS) and ring main units (RMU).

VD4 R circuit breaker Medium voltage indoor circuit breakers

Vacuum and SF6 gas circuit breaker for safe and reliable electrical power distribution or generation in your application up to 46 kV, 4000 A, 63 kA.

Maximize output and productivity with devices that support the continuous operation of your processes, e.g. three times higher mechanical endurance than the standard.

Protect assets with safe and reliable devices, e.g. generator circuit-breaker type tested to the new global dual logo standard (IEC/IEEE 62271-37-013).

Optimize investments with compact devices and high performance, e.g. 17.5 kV/50 kA circuit breaker with 210 mm pole distance.

ABB’s indoor circuit-breakers have been designed to serve your business needs.

With the wide and globally available portfolio we are able to offer you the right fit for the switching of short-circuit currents, overhead lines and cables under load and no load, transformers and generators, motors, ripple control systems and capacitors – even in parallel.

Reliable low-duty protection

VD4/R circuit breakers with lateral operating mechanisms can be used in all medium voltage secondary distribution systems and MV/LV transformer substations in factories, industrial workshops and in the services sector. Thanks to installation (on request) of the self-supplied PR521 overcurrent release with microprocessor, the VD4/R breakers are suitable for use in unmanned MV/LV transformer substations without auxiliary power supply.
