Request QuoteProduct Overview
An electronic device circuit breaker functions as a protective hardware component designed to safeguard sensitive electrical circuits from overcurrent and short-circuit conditions. Units of this classification are typically integrated into control panels and distribution boards to ensure selective shutdown and continuous monitoring of connected loads in automated machinery. Pricing, availability and lead time are confirmed per enquiry through an RFQ.

More info
▲| General | When mounted in rows without convection cooling, the nominal device current should only be led to a maximum of 80% due to the thermal effect during continuous operation (100% operating factor). Special precautionary measures must be taken in systems or machines, to prevent components from restarting (e.g., use of a safety PLC). Parallel connection of multiple circuit breakers is not permitted. |
