Product Description

DAM11 Series Moulded-case Circuit Breaker

Product overview

The DAM11, DAM11LY, DAM11RT, DAM11E, and DAM11EL series are the latest advancements in circuit breakers by Shanghai DaDa Electric Co., Ltd. These innovative models combine the best features of international products with the specific needs of both domestic and global markets.
Designed with an insulation voltage up to 1000V, these circuit breakers are perfect for AC distribution systems with a frequency of 50Hz, a working voltage of 690V, and a working current range from 10A to 800A. They excel in distributing electrical power and protecting circuits and equipment from overloads, short circuits, and under-voltage conditions. Additionally, they are ideal for the infrequent startup of motors, offering robust protection from similar electrical issues.
This product is celebrated for its compact size, high breaking capacity, and minimal flashover, making it an outstanding choice for users. Versatile in installation, it can be mounted either vertically or horizontally.
The DAM11DC series of DC moulded-case circuit breakers are engineered for DC systems with a rated voltage up to 1000V and a current range from 10A to 800A. They are optimized to distribute power efficiently while providing superior protection against overloads and short circuits.
Our products offer flexibility with wiring options from both top and bottom, and they are completely polarity-free for ease of use.
These circuit breakers meet the rigorous standards IEC60947-2 and GB14048.2, ensuring top-notch quality and reliability.

Ambient and installation conditions

Operates reliably at altitudes up to 2000 meters.
The ambient temperature range should be between -5ºC to +40ºC, with marine models accommodating up to +45ºC.
Able to withstand humid environments effectively.
Designed to resist mould growth.
Capable of enduring the effects of nuclear radiation.
Functions optimally with a maximum inclination of 22.5º.
Remains reliable even under normal ship vibrations.
Maintains reliable performance under earthquake conditions (up to 4g).
Suitable for use in environments free from explosive hazards and away from corrosive gases or conductive dust that may damage the metal or insulation.
Should be kept away from rain and snow to ensure longevity and performance.
