Air Circuit Breakers – ACB
Uncompromising … Reliability
Hi-Performance: complete line
Hi-Performance: current ratings in enclosures
This new line of Air Circuit Breakers evolved from a global platform (meeting IEC standards). It is designed for simplicity and manufactured in the European Union.
The L version of this breaker is a line of three and four pole devices ranging from 400A to 4000A in two frame sizes with a fault interruption rating of 50 and 65kA.
Features and benefits
- The design offers a unique combination of high fault current withstand ratings, short fault interruption times and selectivity.
- The device includes a new state-of-the-art highly accurate trip unit that enables the circuit breaker to reliably protect itself and its environment.
- These Power Circuit Breakers are designed to allow multiple interruptions of fault currents and can be used in AC networks with voltages up to 690V.
