Product Description

DAM11 Series Moulded-case Circuit Breaker

Product overview

DAM11, DAM11LY, DAM11RT, DAM11E, and DAM11EL series of circuit breakers are our latest advancements, meticulously developed by Shanghai DaDa Electric Co., Ltd. These innovative devices combine the superior qualities of similar international products while addressing the specific needs of both domestic and global markets.
Designed with an insulation voltage of up to 1000V, these circuit breakers are perfect for AC50Hz distribution systems with a rated working voltage of 690V and a rated working current from 10A to 800A. They expertly distribute electric power and safeguard circuits and power equipment against overload, short circuit, and under-voltage conditions. Additionally, they are ideal for infrequent motor startups, providing protection from overload, short circuit, or under-voltage.
Characterized by their compact size, high breaking capacity, and short flashover, these circuit breakers are the ideal choice for users seeking reliable performance. They offer the flexibility of both vertical and horizontal installation.
The DAM11DC series of DC moulded-case circuit breakers, suitable for DC systems with a rated voltage up to and including DC 1000V and a rated current range of 10~800A, are designed to distribute electric power and protect circuits and power equipment against overload and short circuit.
Our products support top and bottom wiring and are completely polarity-free, ensuring versatile and straightforward installation.
These circuit breakers adhere to the highest standards, including IEC60947-2 and GB14048.2, guaranteeing exceptional quality and performance.

Ambient and installation conditions
