What are the conditions of use for the DC Molded Case Circuit Breaker?

1. The altitude of the installation site of DC Molded Case Circuit Breaker shall not exceed 2000m;

2. The ambient air temperature of DC Molded Case Circuit Breaker should not be higher than +40℃ and not lower than -5℃, and the average value of 24 hours should not exceed +35℃ (except for special orders)

3. The relative humidity of the air at the installation site of DC Molded Case Circuit Breaker. When the maximum temperature is +40℃, it does not exceed 50%, and at a lower temperature, higher relative humidity can be allowed, such as 90% at 20℃. Special measures should be taken for occasional condensation caused by dry temperature changes.

4. There is no explosive medium in the air and no gas and conductive dust that can corrode metals and destroy insulation.

5. A place free from rain and snow.

6. The pollution level is 3.

7. Installation category: The installation category of the main circuit of the circuit breaker is III, and the installation category of the auxiliary circuit and control circuit not connected to the main circuit is II

8. The circuit breaker should be installed and used according to the product instruction manual.

What are the other uses of the DC Molded Case Circuit Breaker?

The DC Molded Case Circuit Breaker can also be used for broken electrical switches. In addition to the trip mechanism, the DC Molded Case Circuit Breaker can also be used as a manual disconnect switch during emergency or maintenance operations. Arcs can be created when the contacts are open. To solve this problem, the DC Molded Case Circuit Breaker has an internal arc suppression mechanism to extinguish the arc.

What are the functional characteristics of DC Molded Case Circuit Breakers?
