Protected
moulded case
type circuit breaker.
The rated insulation voltage of this series of circuit breakers is 400V for currents below 160A and 690V for currents above 250A. It is mainly employed in AC 50Hz systems and boasts a rated
In power distribution networks with currents ranging from 10A to
5
00A and a rated working voltage of 380V/400V, it is engineered to distribute electrical energy efficiently and offer protection against overloads and short circuits in lines and power equipment.
Under standard conditions
,
it also supports infrequent line switching operations.
T
his circuit breaker further provides these protections:
·Fire hazard protection from grounding fault currents undetectable by overcurrent protection systems.
·Protection against ground voltage increase due to insulation failure;
·Circuit breakers with a rated residual action current of 30mA or less can be utilized for personal contact safety.
·Circuit breakers with a rated current of
5
00A and below are also ideal for infrequent motor startups, disconnections during operation, and protection against overload and short circuits in squirrel cage motors.
DAM1L
series circuit breakers can be equipped with various electrical and mechanical accessories, such as separately excited tripping devices, auxiliary contacts, alarm contacts, and rotating handle operating mechanisms.
This versatile series of circuit breakers finds widespread application in construction, transportation, tunnels, residences, and more. The delay type in this series is perfect for branch line
distribution; the adjustable type allows for on-the-spot adjustment of the residual action current or disconnection time.
