Product Description

Introduction

Introducing the exceptional DAM1 series circuit breakers, the pinnacle of electrical safety and efficiency. These circuit breakers are engineered to seamlessly conduct current under normal conditions, while also being equipped with the capability to swiftly interrupt current flow in the event of short circuits, overloads, and other operational disruptions. Designed for electric systems operating with voltages up to 400V, they cater to a vast range of rated currents from 12.5A to 1600A, ensuring broad applicability and robust protection.

Meeting and exceeding the prestigious requirements of EN 60947-1 and EN 60947-2, these circuit breakers are a testament to superior quality and compliance.

Thermal-Magnetic Circuit Breakers: The epitome of reliable protection.

Thermal protection function: Providing impeccable defense against overload conditions.
Our thermal protection mechanism is powered by bimetal technology, ingeniously crafted from two metals with varying thermal expansion coefficients. When heated, the bimetallic strip bends towards the metal with a lower expansion rate, triggering a release mechanism that opens the breaker, effectively halting excessive current flow. The bending speed correlates directly with the current size, thus expertly managing overcurrent protection by responding to currents surpassing the rated threshold. (For protection under short circuit conditions) Another crucial function of the breaker is to safeguard the connected circuit from devastating short circuits. Such occurrences may result from phase-to-phase contacts or phase-to-ground connections. In these scenarios, the surge of high current through the cables necessitates an immediate cessation of system energy to ensure safety. Therefore, the breaker must execute a prompt opening, effectively protecting the load it is connected to. This function is carried out by a sophisticated mechanical opening mechanism, which is activated by the magnetization occurring in the magnetic field created by the short circuit current, providing rapid and reliable protection.
