Product Description

Introduction

Meet the revolutionary DAM1 series circuit breakers, your steadfast partner in maintaining electrical safety and efficiency. Engineered to perfection, these devices effortlessly handle normal current conduction and offer impeccable protection by interrupting circuits during short circuits, overloads, or inadmissible bucking. They are your reliable choice for operational actuation and tripping of electric circuit parts. Specifically designed for electric units operating with an operative voltage up to 400V, they provide unwavering performance across a range of rated currents from 12.5 to a robust 1600A.

These state-of-the-art circuit breakers meet the stringent requirements of EN 60947-1 and EN 60947-2, ensuring unparalleled safety and quality.

Thermal-Magnetic Circuit Breakers:

Thermal protection function: (Delivering exceptional protection under overload conditions)
The ingenious bimetal component is the heart of thermal protection, skillfully crafted from two metals with varying thermal expansion rates. As heat rises, the bimetal elegantly bends toward the less expansive metal, skillfully triggering the notch that initiates the breaker mechanism's opening. The speed at which this bimetal bends is precisely proportional to the level of current traversing the breaker-higher currents lead to increased heat. This remarkable mechanism ensures the breaker provides superior overcurrent protection whenever load currents exceed the rated levels. Magnetic protection function: For comprehensive protection under short circuit conditions, this advanced breaker is equipped to safeguard the connected circuits against any potential short circuits. Such incidents may arise from the unintended contact between phases or interaction between phase and ground. In the event of a short circuit, we witness a dramatic surge of current through the cables, necessitating a swift interruption of system energy to mitigate thermal damage. Rapid breaker response is crucial to protect the connected load, and this protection is expertly managed by a mechanical opening mechanism, a sophisticated system that is activated by magnetization, a result of the magnetic field generated by the short circuit current, ensuring instantaneous and efficient disruption.
