Introduction
DAM1L
series residual current (leakage) circuit breaker (hereinafter referred to as circuit breaker) represents a pinnacle of innovation, crafted to global standards with the latest in advanced manufacturing technology.
Protected
moulded case
type circuit breaker.
This series of circuit breakers boasts a rated insulation voltage of 400V (for Inm less than 160A) and 690V (for Inm more than 250A). They are chiefly employed in AC 50Hz systems and feature a rated
In power distribution networks with currents from 10A to
5
00A and a rated working voltage of 380V/400V, designed to distribute electrical energy while providing robust protection against overloads and short circuits in lines and power equipment.
Under standard operating conditions
,
it can also be utilized for infrequent line switching.
T
his circuit breaker is also equipped with the following protective features:
·Protection against fire hazards from grounding fault currents undetectable by overcurrent protection.
·Protection against the escalation of ground voltage due to insulation damage;
·Circuit breakers with a rated residual action current not exceeding 30mA serve as protection against personal contact.
·Circuit breakers with a rated current of
5
00A and below are also suitable for the sporadic starting, disconnection during operation, and protection against overload and short circuit in squirrel cage motors.
DAM1L
series circuit breakers are compatible with a variety of electrical and mechanical accessories, including separately excited tripping devices, auxiliary contacts, alarm contacts, and rotary handle operating mechanisms.
This series of circuit breakers finds extensive application in construction, transportation, tunnels, residential areas, and more. The delay type in this series is ideal for branch line
distribution; the adjustable type allows for on-site adjustments of the residual action current or disconnection time.

Remarkably, even if the operating power voltage of the circuit breaker's residual current protection circuit drops to 50V, it continues to function impeccably, ensuring dependable protection. (I coherence n=30mA)
This versatile series offers diverse classifications: B type (basic breaking capacity) for Inm less than 100, S type (standard breaking capacity), and H type (high score breaking capacity).
With an impressive high score breaking capacity (Inm > 160), these circuit breakers are engineered to adapt to various demanding environments.
The main circuit of our circuit breaker can be connected in multiple ways, providing enhanced flexibility and convenience:
-
Piston front connection
-
Terminal extension plate front connection
-
Screw connection at the rear of the piston plate
