Product Description

Introduction

Introducing the renowned DAM1 series circuit breakers! These breakers are meticulously crafted to ensure seamless current conduction during normal operations and provide swift disconnection in the face of short circuits, overloads, and inadmissible bucking. Exceptionally designed for electric units, they maintain an operative voltage cap of 400V and accommodate a rated current range from 12.5A to an impressive 1600A.

These circuit breakers meet and exceed the stringent standards of EN 60947-1 and EN 60947-2.

Thermal-Magnetic Circuit Breakers:

Thermal Protection Function: (Ensuring Safety Under Overload Conditions)
Our advanced bimetal technology ensures impeccable thermal protection. This ingenious bimetal, composed of two metals with distinct thermal expansion rates, bends towards the metal with lesser expansion when heated. This bending action releases a notch, activating the breaker's mechanism to halt the circuit. The bending speed is proportionate to the current size, effectively providing overcurrent protection as the heat rises with increased current, ensuring safety at load currents surpassing the rated capacity.
Magnetic Protection FunctionEssential for Short Circuit Protection: Another critical function of our breaker is tosafeguard the connected circuit against short circuits. When phases come intocontact with each other or phase-ground, a short circuit may occur,resulting in a significant surge of current through the cables. To prevent damage,the system energy must be interrupted swiftly. This is where the thermalprotection comes into play. The breaker responds instantly to protectthe connected load. The pivotal component responsible for thisprotection is the mechanical opening mechanism, whichoperates on the principle of magnetization. This mechanism istriggered by the magnetic field generated by the short circuit current,ensuring prompt and effective disconnection.With our state-of-the-art distribution breakers,you are assured unparalleled protectionand reliability for all your electrical needs.
