TOMZN TOBIZ-125 2P 125A DC Miniature Circuit Breaker (MCB)

TOMZN TOBIZ-125 2P 125A DC Miniature Circuit Breaker is designed for overload and short-circuit protection in high-current DC electrical systems. The breaker features a two-pole configuration with a rated current of 125A, providing simultaneous isolation of both DC conductors. It is suitable for solar PV systems, lithium battery systems, inverter-to-battery connections, DC distribution equipment and other high-current DC applications. The TOBIZ-125 series uses a C-curve tripping characteristic and is designed to provide automatic circuit protection against abnormal overload and short-circuit conditions. Its DIN-rail design allows convenient installation inside DC protection boxes, battery distribution panels and solar electrical systems. TOMZN offers this 125A 2P platform in different DC voltage configurations, including 600V and 1000V variants. The correct voltage rating should therefore be selected according to the actual product label and system design.
