Product Description

DZ47B battery miniature circuit breaker is a new product specially developed for low-voltage batteries such as photovoltaic solar UPS. DZ47B battery circuit breaker supports overload protection between 12-240V and short-circuit protection between 36-240V. The battery circuit breaker adopts B-curve (3-5ln) tripping capability, sensitive to tripping; battery circuit breaker has 1 pole to protect the positive or negative pole, 2 poles to protect the positive and negative poles at the same time, 1P+1P switches 2 positive power supplies or 2 negative power supplies (switching standby Power supply and common power supply), 2P+2P switching 2 battery switches (switching standby power supply and common power supply), four specifications; the minimum current of the battery switch can be 1A, and the maximum current can reach 150A.

NORMAL OPERATING CONDITIONS AND INSTALLATION CONDITIONS

The upper limit of ambient temperature does not exceed +40 °C, the lower limit does not less than -5°C, and the average temperature of 24h does not exceed +35 °C.
