Protected
moulded case
type circuit breaker.
The rated insulation voltage of this series of circuit breakers is 400V (for Inm less than 160A) and 690V (for Inm more than 250A). It is primarily used in AC 50Hz systems and has a rated
In power distribution networks with currents ranging from 10A to
5
00A and a rated working voltage of 380V/400V, it is designed to distribute electrical energy and provide protection against overloads and short circuits in lines and power equipment.
Under normal conditions
,
it can also be used for infrequent line switching.
T
his circuit breaker also offers the following protections:
·Protection against fire hazards from grounding fault currents undetectable by overcurrent protection.
·Protection against rising ground voltage due to insulation damage;
·Circuit breakers with a rated residual action current not exceeding 30mA can be used for personal contact protection.
·Circuit breakers with a rated current of
5
00A and below can also be used for the infrequent starting, disconnection during operation, and overload and short circuit protection of squirrel cage motors.
DAM1L
series circuit breakers can be fitted with various electrical and mechanical accessories, including separately excited tripping devices, auxiliary contacts, alarm contacts, and rotating handle operating mechanisms.
This series of circuit breakers is widely used in construction, transportation, tunnels, residences, and more. The delay type in this series is suitable for branch lines
distribution; the adjustable type allows on-site adjustment of the residual action current or disconnection time.
