Product Description

Product Model: DAM11 Series: Moulded-case Circuit Breaker

Product overview

The DAM11 series, including DAM11, DAM11LY, DAM11RT, DAM11E, and DAM11EL, represents our latest innovation in circuit breaker technology. These upgraded models are crafted by integrating the superior features of leading international products with 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 current range from 10A to 800A. They are essential for distributing electrical power, protecting circuits and equipment from overload, short circuits, and under-voltage, and can also handle the infrequent startup of motors, safeguarding them against similar issues.
Offering a compact size, high breaking capacity, and minimal flashover, our circuit breakers are the ideal choice for users. Their versatile design allows for both vertical and horizontal installation.
The DAM11DC series DC moulded-case circuit breakers are engineered for DC systems with voltages up to 1000V and currents ranging from 10A to 800A. These breakers are vital for distributing electrical power and protecting circuits and equipment from overload and short circuits.
Our products feature flexible wiring options, allowing for power feeds from both the top and bottom, and they are designed to be polarity-free for ease of installation.
Compliance: Meets standards IEC60947-2 and GB14048.2, ensuring top-tier quality and reliability.

Ambient and installation conditions

Operational Altitude: Reliable up to 2000m.
Ambient Temperature: Operational between -5ºC to +40ºC, and up to +45ºC for marine environments.
Humidity Resistance: Designed to withstand damp air conditions.
Mould Resistance: Built to resist mould effects.
Radiation Resistance: Capable of withstanding nuclear radiation.
Maximum Inclination: Operational up to a 22.5º inclination.
Vibration Resistance: Reliable performance even under normal ship vibrations.
Seismic Performance: Remains reliable during earthquakes (4g).
Safe Environments: Suitable for locations free from explosive hazards and away from corrosive gases or conductive dust that could damage metal or insulation.
Weather Resistance: Must be kept away from rain and snow to ensure optimal performance.
