Introduction
DAM1L
series residual current (leakage) circuit breaker, henceforth referred to as the circuit breaker, represents a top-tier series, expertly crafted with designs adhering to international standards and utilizing pioneering manufacturing techniques.
Protected
moulded case
type circuit breaker.
This series of circuit breakers is engineered with a rated insulation voltage of 400V for Inm below 160A, and 690V for Inm exceeding 250A. It is notably employed in AC 50Hz systems and holds a rated
In power distribution networks handling currents between 10A and
5
00A, with a rated operational voltage of 380V/400V, it is specifically designed to allocate electrical power while providing robust protection against overloads and short circuits in power lines and equipment.
Under standard conditions
,
this breaker can also serve for occasional line switching.
T
his circuit breaker further provides these protections:
·Protection from fire hazards due to grounding fault currents not detected by overcurrent protection.
·Protection against increasing ground voltage derived from insulation failure;
·Circuit breakers with a residual operating current rating not exceeding 30mA are suitable for protection against personal contact.
·Circuit breakers rated at
5
00A and lesser can also be utilized for the occasional initiation, disconnection during use, and safeguarding squirrel cage motors from overloads and short circuits.
DAM1L
series circuit breakers are compatible with a diverse range of electrical and mechanical accessories, including separately excited tripping devices, auxiliary contacts, alarm contacts, and rotating handle operational mechanisms.
This versatile series of circuit breakers is widely adopted in construction, transportation, tunnels, residential areas, and beyond. The delay type is particularly suited for branch line
distribution; the adjustable type provides the flexibility to modify the residual operating current or disconnection duration on-site.
