P&B VOR-S-Brush VSI
P&B offer two types of Vacuum Oil Replacement breaker to replace bulk oil and vertically isolated vacuum breakers. Their VOR-S typically incorporates an ABB VD4 spring-operated vacuum circuit breaker. For customers who prefer an alternative to the spring mechanism, GFF and P&B can offer the VOR-M breaker, which utilises ABB’s proven embedded vacuum interrupter poles, driven by a high-duty and reliable magnetic actuator.
An extensive range of type tests have been performed in independent, accredited laboratories, to validate the integrity of each retrofit design.
