Introduction
The DAM1L
series of residual current (leakage) circuit breakers, expertly crafted as a state-of-the-art series, created with international standard designs and groundbreaking manufacturing technology.
Protected
moulded case
type circuit breaker.
Featuring a rated insulation voltage of 400V (for Inm less than 160A) and 690V (for Inm more than 250A), this series is predominantly used in AC 50Hz systems with a rated
In power distribution networks supporting currents between 10A to
5
00A, and a rated working voltage of 380V/400V, it is engineered to distribute electrical energy effectively and ensure protection against overloads and short circuits within lines and power equipment.
Under optimal conditions
,
it can also be utilized for infrequent line switching with ease.
T
his sophisticated circuit breaker additionally provides the following protections:
·Protection against hazardous fire risks stemming from grounding fault currents not detectable by overcurrent protection systems.
·Defense against rising ground voltage due to insulation degradation;
·Circuit breakers with a rated residual action current capped at 30mA offer personal contact protection.
·Circuit breakers with a rated current of
5
00A and under can also be applied for infrequent motor starting, operational disconnection, and providing overload and short circuit protection for squirrel cage motors.
The DAM1L
series circuit breakers are adaptable with a plethora of electrical and mechanical accessories, including separately excited tripping devices, auxiliary contacts, alarm contacts, and rotating handle operating mechanisms.
This versatile series of circuit breakers is widely embraced in construction, transportation, tunnels, residential applications, and beyond. The delay type within this series is tailor-made for branch lines
distribution; the versatile adjustable type enables on-site adjustment of the residual action current or disconnection time.
