The case of choosing a slow-blow fuse
Generally speaking, inductive loads such as motors and valves use slow-melt fuses.
When the load is a large current load (above 20A), choose a slow-blow fuse, such as after defrosting;
Slow-blow fuses are used for long-term pulse loads, such as motor loads such as glass lift motors;
When there is a lock current load, choose slow blow insurance, such as wiper motor, door lock motor, electric seat and other loads
Slow-blow fuses are commonly used JCASE fuses, MIDI fuses and Mega fuses.
The specification of JCASE fuse is 20~60A. It is mainly suitable for large current loads such as rear defrosting, air conditioning blower, cooling fan, etc.
Midi fuse specifications are 30~200A, suitable for loads with a current not exceeding 200A, such as the large fuse at the battery fuse box.
The specification of Mega fuse is 40~500A, the product with the highest rated current on the market at present, suitable for circuit protection of high current and high pulse. Such as battery, generator protection.
