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.

This series of circuit breakers takes advantage of multi-phase power supply for the residual current protection circuit, unlike earlier versions that relied on single-phase power. This innovation ensures a more reliable and stable power supply.
t
The residual current protection circuit of the device continues to operate effectively even when the operating power voltage drops to 50V, maintaining its protective function seamlessly. (In coherence n=30mA)
This series of circuit breakers is available in three classifications: B type (basic breaking capacity for Inm < 100), S type (standard breaking capacity), and H type (high breaking capacity for Inm > 160), catering to various application needs.
High score breaking capacity (Inm > 160) ensures robust performance and safety across diverse applications.
The main circuit of a circuit breaker can be connected in several versatile ways:
-
Piston front connection for secure and efficient set-up.
-
Terminal extension plate front connection for flexible installation.
-
Screw rear connection on the piston plate for added stability and security.
