DC Molded Case Circuit Breaker
DC MCCBApplication
SM1 Series DC MCCB adopt international advanced design,
manufacturing technology and developed a new circuit breaker,
the rated voltage DC550V and below, rated current up to 800A of circuit.
Circuit breaker has a short circuit, overload protection,
to protect lines and power equipment from damage.
Features
1)SM1 series DC circuit breaker, interrupter technique patented by the international first CCV,
or quad speed and narrow arc breaking free consumer technology,
so that arcing distance shorter, higher breaking capacity.
2)Small size, short time delay circuit accurate, complete specification.
3)Standards are usually chosen according to circumstances,
for battery power system differential with, you can simplify the calculation of short circuit current,
no need to consider resistance, cable cross-sectional area, copper content, limiting factor,
cable parameters such as thermal stability.
Simply click on the lower circuit breaker rated current level of choice,
can achieve all three sections of selective protection, the performance of international standards.
4)SM1 Series DC Molded Case Circuit Breaker in the corrosion resistance,
the use of the world's most advanced anti-corrosion surface treatment to increase hardness and soft-nitriding process plus gloss plating, corrosion performance of the product higher than nickel,
used for high protection level.
Normal operation and mounting requirement
1)Circumstance temperature -5°C ~ +40°C, Derating above 40 °C can be used.
2)Altitude above sea level less than 2000 m.
3)Humidity not exceeding 50% at 40°C and not exceeding 90% at 25°C.
4)Installation class II or III.
5)Pollution class 2.
6)Installation method DIN Rail mounting type.
7)The external magnetism shall not be more than 5 times of terrestrial one.
8)Product shall be installed at the place where there shall be no severe impact and vibration.
9)Product shall be vertically mounted onto standard Din rail 35mm.
