Product Overview:

SL7-63 series circuit breaker is a DC circuit breaker with overload and short circuit protection, diode voltage DC440V, DC550V, DC800V and below, the four-pole voltage DC1000V DC1200V overload short circuit protection of DC system and below. It is widely used in distribution box system of DC Screen, DC Water Pump, DC distribution cabinet, DC junction box, photovoltaic and wind power station. It can also be used for infrequent on-off conversion of lines under normal circumstances.

Working conditions and installation conditions

The ambient air temperature	Not higher than + 40℃, not lower than-5℃, and the average value of 24 hours is more than + 35℃;
Altitude	The altitude of the installation site exceeds 2000m;
Graceful conditions	Graceful of the relative humidity in the ambient up to +40 ℃ is not more than 50% at a lower temperature can have a higher relative humidity, for example at 20 ℃ of 90%, for condensation occasionally caused by temperature change ratio, protective measures should be taken, such as installing protective cover, etc;
Installation conditions	The installation position should be vertical, the inclination in all directions should be more than 10 °, and it should be installed in the place without shock, vibration and rain and snow.
Pollution level	Level 2
Setup class	Level II or Level III
Protection level	IP20 (installed in distribution box, distribution cabinet or box IP40).
