Product Description

Introduction

The DAM1 series circuit breakers are meticulously crafted for uninterrupted current conduction in normal conditions and are engineered to swiftly switch off during short circuits, overloads, and other inadmissible conditions. These breakers ensure flawless operational actuation and tripping of electric circuit parts. Designed to excel in electric units with an operative voltage capped at 400V, they cater to a wide range of rated currents from 12.5 to 1600A.

They meet and exceed the stringent standards of EN 60947-1 and EN 60947-2, ensuring reliability and safety.

Thermal-Magnetic Circuit Breakers:

Thermal Protection Function: (Designed for protection under overload conditions)
The bimetal component, integral to our thermal protection, is a sophisticated blend of two metals with varying heat extension coefficients. When heated, the bimetal bends towards the metal with the lesser extension coefficient, triggering a notch that activates the breaker mechanism to disconnect the circuit. The bending speed of the bimetal directly correlates with the current passing through the breaker, as an increase in current results in heightened heat. This ensures overcurrent protection by the bimetal for load currents exceeding the rated current.
Magnetic Protection Function:(Engineered for protection under short circuit conditions) Another crucial role of the breaker is tosafeguard the connected circuit against shortcircuits. Short circuits may arise from phase-to-phase orphase-to-ground contacts. The passage ofan extraordinarily high current through the cables during a short circuit necessitatesan immediate system shutdown to prevent damage. The system energymust be halted in record time dueto thermal protection demands. The breakeris designed to instantly open, thereby safeguarding the loadit is connected to. The mechanical openingmechanism that ensures this functionoperates with unparalleled efficiency, driven bymagnetization induced by the magnetic field created by the short circuit current.
