125A Adjustable Moulded Case Circuit Breaker

CDADA DAM11 125A Adjustable Moulded Case Circuit Breaker is an upgraded high-performance moulded case circuit breaker independently developed by Shanghai DADA Electric. With adjustable tripping parameters, 1000V insulation voltage, 690V working voltage, and 125A rated current, it provides full overload, short-circuit, and undervoltage protection for AC distribution systems.

Adopting current-limiting technology, patented contact repulsion device, and modular design, it is widely used in power distribution, motor protection, and industrial electrical systems, and is the first choice for global buyers, distributors and OEM customers.

Product Functions

● Overload long-delay protection

● Short-circuit short-delay & instantaneous protection

● Undervoltage & shunt tripping protection

● Adjustable current & time parameters

● Motor infrequent startup & protection

● Circuit isolation & safe control

● Modbus communication & remote monitoring (intelligent type)
