Features
◆ It can be used as the main switch protection for high-power solar systems.
◆ The DC MCCB has a higher DC voltage, so the high section capability of the DC ◆ MCCB is very suitable for DC systems.
◆The operating mechanism of the DC circuit breaker has fast closing and fast breaking functions, compact structure, small size and easy to use.
◆ It has a thickened handle for flexible handling.
FAQ
Q:Is there any discount you can offer?
A:Yes, for large quantities, we offer better prices.
Q:How do I choose an MCCB?
A:Load. The current carrying capacity (In, A) of the circuit breaker should be higher than the expected load in the circuit.
