Product Description

Introduction

The DAM1 series circuit breakers are your ultimate solution for reliable electrical safety and efficiency. These advanced breakers are meticulously engineered to handle current seamlessly during normal operations and swiftly interrupt it during anomalies such as short circuits, overloads, or operational faults. Suitable for electric units with operational voltage up to 400V, they cater to rated currents ranging from 12.5 to a robust 1600A, ensuring comprehensive protection and performance.

They adhere to the stringent standards of EN 60947-1 and EN 60947-2, providing assured compliance and premium quality.

Thermal-Magnetic Circuit Breakers:

Thermal protection function: Tailored to offer exceptional protection under overload conditions, ensuring system integrity and longevity.
Bimetal, the core of thermal protection, ingeniously combines metals with varying expansion coefficients. Upon heating, this bimetallic strip bends towards the metal with lesser expansion, triggering a mechanism that opens the breaker, effectively interrupting the circuit. The bending rate is directly correlated to the current's magnitude, as higher currents intensify heat. Thus, this precise response ensures robust overcurrent protection beyond rated levels by the bimetal. Magnetic protection function: (For protection under short circuit conditions) Another vital function of the breaker is to safeguard the connected circuit against damaging short circuits. Such incidents might arise from the unintended contact between phases or a phase-ground connection. During these occurrences, an immense current surge may flow through the wiring, necessitating an immediate cessation of power to prevent thermal damage. The breaker is designed for prompt disconnection to shield the load it serves. The mechanism responsible for this protection is a sophisticated mechanical opening mechanism activated by the magnetic force generated within the magnetic field induced by the short circuit current, ensuring quick and reliable response.
