Introduction:
- 20A mini circuit breakers (MCBs) are core protection and control components in low-voltage small-scale power distribution systems. They can automatically disconnect the power supply when overload or short-circuit faults occur in the circuit thus to prevent equipment damage or fires and other safety accidents.
- The casing of our 20A Mini Breaker is made of Class A flame-retardant material to prevent the risk of fire at high temperatures.
- The miniature circuit breaker tripping curve can be type B, type C, or type D. Different curves are suitable for different applications; for example, type B curve is suitable for domestic use, type C curve is suitable for small motors or commercial use, and type D curve is more suitable for industrial use.
- Our 20A Mini Breaker are suitable for various applications including residential lighting, mains switches, public buildings, industrial power distribution rooms, new energy sources, public service facilities, and office buildings.
- CNTN Electric’s 20 amps miniature circuit breaker is very compact in size, making it easy to install. Its overall dimensions are only 7.7*6.5*1.7 cm.
- CNTN Electric manufactures 20 A miniature circuit breakers with high reliability and quality. The rated current (A) of these miniature circuit breakers ranges from 6 A to 63 A, and the rated voltage is 5-220 VAC.
