New circuit breakers in the ВА88 MASTER KARAT IEK line feature compact dimensions, allowing them to be installed even in limited space. VA88-31 size devices are equipped with thermomagnetic releases for currents from 10 to 63 A and can be used in incoming cabinets, distribution boards, control panels, etc.
The VA88 MASTER KARAT IEK series is designed to protect electrical networks from short-circuit currents and overload, unacceptable voltage drops, and to conduct current in normal mode. It includes circuit breakers of 6 frame sizes for currents from 10 to 800 A. The design allows for independent installation of additional devices.
