Introduction
DAM1L
series Residual Current (Leakage) Circuit Breaker is a newly developed series, designed and manufactured using international standards and advanced technology.
Protected
Moulded Case
Type Circuit Breaker.
The rated insulation voltage of this series is 400V (Inm < 160A) and 690V (Inm > 250A). It is mainly used for AC 50Hz and rated
In a power distribution network with current ranging from 10A to
5
00A and a rated working voltage of 380V/400V. It is utilized for distributing electric energy and protecting against overload and short-circuits in power equipment and lines.
Under normal conditions
,
It can also be used for infrequent switching of lines.
T
his circuit breaker also offers the following protections:
·Protection against fire hazards due to grounding fault currents that cannot be detected by overcurrent protection.
·Protection against increased ground voltage due to insulation damage.
·Personal protection from contact with circuit breakers having a residual action current not exceeding 30mA.
·Circuit breakers with rated current of
5
00A and below can be used for infrequent starts, breaking off during operation, and overload & short-circuit protection of squirrel cage motors.
DAM1L
series circuit breakers can be equipped with electric and mechanical accessories for various applications, such as separately excited tripping devices, auxiliary contacts, alarm contacts, and rotating handle operating mechanisms.
This series is widely used in construction, transportation, tunnels, residences, etc. The delay type is used for branch line distribution and the adjustable type is for on-site current or disconnection time adjustments.
Distribution of roads;Adjustable type is used to adjust the residual action current or disconnection time on site.

This series of circuit breakers feature a residual current protection circuit powered by a multi-phase supply, unlike earlier models that relied on a single-phase supply.
t
The device's residual current protection circuit remains fully operational even when the operating power voltage drops to 50V, ensuring continuous protection. (In conformity with n=30mA)
This series is categorized into B type (basic breaking capacity with Inm less than 100), S type (standard breaking capacity), and H type.
High breaking capacity (Inm > 160) variant, suitable for demanding applications.
The main circuit of the circuit breaker can be connected in various ways:
-
Piston front connection.
-
Terminal extension plate front connection.
-
Screw connection at the rear of the piston plate.
