DC 250A Breaker waterproof

The function of the 250A DC circuit breaker is to serve as an overload and short-circuit protection device in DC circuits, quickly cutting off the power supply when the current rises abnormally, ensuring the safety of equipment and personnel.

Overload protection: When the load current continues to exceed the rated value (such as 250A), the circuit will trip with a delay to prevent damage to the line or equipment due to long-term overheating.

Short circuit protection: In the event of a short circuit fault (instantaneous surge of current), the circuit breaker quickly disconnects the circuit through an electromagnetic trip mechanism (usually in milliseconds) to prevent fire or equipment damage.
