Product Description

DAM11 Series Moulded-case Circuit Breaker

Product overview

The DAM11, DAM11LY, DAM11RT, DAM11E, and DAM11EL series of circuit breakers represent the pinnacle of innovation, meticulously researched and developed by Shanghai DaDa Electric Co., Ltd. These state-of-the-art circuit breakers combine the best attributes of international products with the demands of both domestic and global markets.
Designed for distribution systems of AC50Hz, our circuit breaker boasts an insulation voltage up to 1000V, supporting a rated working voltage of 690V and a working current ranging from 10A to 800A. It is engineered to distribute electrical power, safeguard circuits and power equipment from overloads, short circuits, and under-voltage conditions. Additionally, it can be employed for the infrequent startup of motors, providing reliable protection against overloads, short circuits, and under-voltage scenarios.
Featuring a compact size, high-breaking capacity, and short flashover, the DAM11 series is the ideal solution for savvy users. Its versatile design allows for both vertical and horizontal installation.
The DAM11DC series DC moulded-case circuit breaker is expertly crafted for DC systems with rated voltages up to DC 1000V and rated currents from 10A to 800A. This superior circuit breaker is adept at distributing electrical power and protecting equipment from overloads and short circuits.
Our products ensure versatile connectivity with the capability to be wired from both the top and bottom, while being completely polarity-free.
Adhering to the stringent standards of IEC60947-2 and GB14048.2, our products guarantee unmatched reliability and safety.
