MAGNETIC ACTUATOR VCB

The ISM series magnetic actuator vacuum circuit breaker is the result of extensive R&D efforts to provide outstanding performance for compact switchgear designs, retrofit solutions, and special applications.

 

After nearly 30 years on the market, the VCB install base has exceeded 500,000 units worldwide, continuing to solve the most ambitious customer problems.

MAINTENANCE FREE

The switching module’s robust design guarantees up to 50,000 rated current and 100 full rated short circuit CO operations with no maintenance required.

CONTINIOUS SELF-SUPERVISION

The whole trip and close circuit supervision come in a single package with any VCB. In the event of a malfunction, it will be indicated locally with LED and remotely via relay contacts.

ULTRA-COMPACT AND LIGHTWEIGHT

With a weight starting from 33 kg, the circuit breakers are the lightest in their class which significantly simplifies the installation process.

ANY SPATIAL ORIENTATION

Adjustment and mounting flexibility for the optimization of switchgear design, which allows to define how to make primary and secondary connections, saving even more space

HIGH OPERATIONAL SPEED

Opening and closing times as low as 12 ms and 24 ms respectively, enabling the implementation of fast transfer switching, arc flash mitigation or fault current limitation.

SINGLE PHASE OPTION

The perfect match for applications like transformers or generators with neutral earthing, server rooms and point on wave switching.
