1.Application

1.Application

ADM3 series moulded case circuit breaker (hereinafter referred to as circuit breaker) is anew circuit breaker product developed by our company, with a new industrial appearancedesign, the product shows the fashionable, atmospheric sense of quality; productspecifications can be covered from 125A to 800A case frame current; compact productvolume, as well as the detachable design of the cover brings accessories independentinstallation function, greatly improving the convenience of the product; the product has asmall size, high breaking, short flying arc. its rated insulation voltage up to 1000V, suitablefor AC 50Hz or 60Hz, rated working voltage up to 690V, rated working current from 10A to800A in the power distribution network, used to distribute power and protect the line andpower supply equipment from overload, short circuit and under voltage fault damage; at thesame time as the line infreauent The circuit breaker has an isolation function and itscorresponding function is to protect the circuit and power supply equipment from overload.short-circuit and under-voltage faults. This circuit breaker has an isolation function, thecorrespondingsymbols ofwhich arek.The circuit breaker can be installed vertically or horizontally.The product meets the requirements oflEC60947-2 and GB/T14048.2

2.Product range

2.1 Normal working conditions: (1)The product has protection class lP30 and pollution class 3.

(2) The ambient air temperature should not be higher than +40'C and not lower than -5°C, and the24h average temperature should not exceed +35'C.

(3)The altitude of the installation site should not exceed 2000m.

(4) The relative humidity of the atmosphere does not exceed 50% at an ambient temperature of+40'C, with higher relative humidity possible at lower temperatures,e.g.90% at 20°C. Specialmeasures should be taken for occasional condensation due to temperature changes.
