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.

Superior build quality
Strong anti-interference capabilities ensure reliable performance.
Wide range of versatile accessories available.
This series boasts a residual current protection circuit powered by a multi-phase power supply for enhanced reliability, compared to earlier models powered by single-phase supply.
Durable construction
The residual current protection circuit operates seamlessly, even when the operating power voltage drops to 50V, ensuring consistent performance. (I coherence n=30mA)
These circuit breakers are available in three classifications: B type for basic breaking capacity (Inm < 100), S type for standard breaking capacity, and H type for higher breaking capacity scenarios.
Impressive high-score breaking capacity (Inm > 160) makes them suitable for diverse applications.
The main circuit can be connected through various methods:
-
Piston front connection for secure setup
-
Front connection with terminal extension plates for flexibility
-
Screw connection at the rear of the piston plate for robust installation
