Introduction
DAM1L
series residual current (leakage) circuit breaker (hereinafter referred to as circuit breaker) is a new series of residual current (leakage) successfully developed by using international standard design and advanced manufacturing technology.
Protected
moulded case
type circuit breaker.
The rated insulation voltage of circuit breakers of this series is 400V (Inm is less than 160A) and 690V (Inm is more than 250A), which is mainly used for ac 50Hz and rated
In a power distribution network with a current of 10A~
5
00A and a rated working voltage of 380V/400V, it is used to distribute electric energy and protect the overload and short circuit of lines and power equipment.
Under normal conditions
,
It can also be used for infrequent switching of lines.
T
his circuit breaker also has the following protection:
·It provides protection for fire hazards caused by grounding fault current that cannot be detected due to overcurrent protection.
·Provide protection against the danger of increasing ground voltage due to insulation damage;
·Circuit breakers with rated residual action current not exceeding 30mA can be used for personal contact protection.
·Circuit breakers with rated current of
5
00A and below can also be used for infrequent start, break off during operation and overload and short circuit protection of squirrel cage motors.
DAM1L
series circuit breakers can be equipped with electric accessories and mechanical accessories for various purposes, such as separately excited tripping device, auxiliary contact, alarm contact and rotating handle operating mechanism.
This series of circuit breakers are widely used in construction, transportation, tunnel, residence, etc.The delay type in this series of circuit breakers is used for branch lines
Distribution of roads;Adjustable type is used to adjust the residual action current or disconnection time on site.

°
Strength and reliability in every component.
Boasting exceptionally strong anti-interference capabilities, our circuit breakers ensure uninterrupted performance.
° A wide range of accessories ensures our circuit breakers can be easily customized to fit any installation.
Innovatively designed, the working power for the residual current protection circuit in this series is supplied by a multi-phase power source, significantly enhancing reliability compared to early models that relied on single-phase power.
t
When the operating power voltage of the circuit breaker's residual current protection circuit drops to 50V, the system continues to function seamlessly, maintaining protection with a coherence of 30mA.
Our circuit breakers are categorized into three types: B type for basic breaking capacity (Inm < 100), S type for standard breaking capacity, and H type for high breaking capacity.
For high-demand applications, our high score breaking capacity models (Inm > 160) are engineered to meet and exceed your needs.
The versatile main circuit of our circuit breakers offers multiple connection options:
-
Piston front connection for straightforward integration.
-
Terminal extension plate front connection for enhanced versatility.
-
Rear screw connection at the piston plate for secure and reliable attachment.
