Fuse Protection Principle
As a passive overcurrent protection device, the fuse is the last line of defense for circuit safety. When a serious overload or short circuit occurs, the fuse fuses itself to forcibly cut off the current path, achieving the following effects:
- Prevents wire overheating and fire hazards
- Protects connected equipment from overcurrent damage
- Protects upstream power distribution equipment (such as transformers, switchgear) from short-circuit current impact
- Provides indirect contact electric shock protection for operators
- Cuts off ultra-high fault current in milliseconds during phase-to-phase faults, suppresses arc energy, and avoids catastrophic faults
- Only isolates the faulty circuit to ensure that the power supply of other branches is not affected
Application Scenarios
Indoor Applications (2P 30A)
Main switch of residential/commercial distribution boxes, control and protection of industrial equipment (machine tools, fans, water pumps), indoor air conditioners, water heaters, indoor charging piles, indoor power distribution of small photovoltaic/energy storage systems.
Outdoor Applications (60A 2P/3P)
Outdoor air conditioners, heat pumps, water pumps, ventilation equipment, outdoor charging piles, photovoltaic combiner boxes, energy storage systems, temporary power supply for construction sites, street lamp control, agricultural irrigation, power supply for breeding equipment, factory distribution panels, commercial building distribution cabinets.

FAQ
Q: Can indoor models be used outdoors?
A: No. The indoor model has a protection level of IP20 and does not have rainproof and dustproof functions. Using it outdoors will cause equipment failure and safety risks. Please choose the IP65/NEMA 3R outdoor model for outdoor use.
Q: What specification of fuse should I choose?
A: It is recommended to choose gG/gL type fuses matching the switch current. For example, 30A switches are equipped with 25-30A fuses, and 60A switches are equipped with 50-60A fuses. We can also provide professional selection suggestions according to your specific load.
Q: Do you provide sample testing?
A: Yes. We can provide samples for testing, and the sample fee can be deducted from the payment of bulk orders.
