First, the scope

DZ47-100 (NC ) 125A Series high current Miniature Circuit Breaker has a short-circuit protection circuit overload, for lighting distribution system and motor distribution system. Looks compact, light weight, excellent performance, reliable, high breaking capacity, blurted quickly, rail, housing and components of high impact resistant plastic combustion stage, long life, it is mainly used for AC 50Hz or 60Hz, rated unipolar voltage 230, two, three, four pole 400V; rated current of 50A to 125A circuit for overload, short circuit protection, but also can not frequent on-off electrical equipment and lighting circuit under normal conditions. Can be equipped with undervoltage release, shunt releases and other accessories, it is also applicable to the isolation switch and as a line under-voltage protection and remote disconnect purposes.
DZ47-100 in line with IEC60947-2, GB14048.2, GB10963 standard Claim.


Second, model and specification



Third, the structural characteristics

DZ47-100 Small circuit breakers , were available for 35mm rail card installation, small size, high breaking capacity, with a visible indicator of the contacts are closed, it can be used as the line of isolation purposes. Use TH35-7.5 Standard steel rail for installation.

Seven, the main parameters and technical performance

◆ main types:
aC type is mainly used for lighting distribution protection (instantaneous removal Buckle 5 ~ 10ln)
bD is mainly used for industrial power distribution protection (instantaneous Tripping 10 ~ 16ln)
◆ circuit breakers rated current of 50A, 63A, 80A , 100A, 125A
◆ breaker is divided into: unipolar, two-pole, three poles, four poles
◆ The breaker for embedded installation (the installation mounting rail)
◆ rated working voltage of the circuit breaker and its associated rated Short circuit breaking capacity 10KA.
◆ frequency withstand voltage: After the heat-resistant properties, breaker should be able to withstand 2500V frequency voltage withstand test for 1 minute without insulation flashover and breakdown.
◆ mechanical and electrical life: mechanical and electrical life of the circuit breaker 2000 times, 6000 times the electrical life.
◆ Anti-heat resistance: Class 2 (temperature fifty-five When degrees Celsius, relative humidity of ninety-five%)
◆ Wiring: The band clamp terminals, fixed As for cable cross sections up to 50mm?
