Practical Application Cases

1. Marine Yacht Electrical System Application Case

A Southeast Asian marine equipment distributor purchased Yiqi 12V-48V Waterproof Manual Reset Circuit Breaker in bulk for electrical retrofitting projects on yachts and fishing boats. The marine environment is consistently humid, with frequent water splashes and strong vibrations, placing extremely high demands on circuit protection equipment. This product's fully sealed structure effectively resists seawater corrosion and water intrusion. When marine propulsion motors or vehicle audio systems experience current overload, it can quickly cut off power to protect the equipment. After troubleshooting, it can be quickly manually reset to restore power. After application, the customer saw an 85% reduction in the failure rate of marine electrical equipment, significantly reducing maintenance costs.

2. Industrial DC Auxiliary Equipment Application Case

A domestic automation company applied Yiqi CB-01 circuit breakers to its factory's DC power distribution and mechanical control circuits. The factory production environment is dusty, with continuous equipment vibration, easily leading to short circuits and overload hazards. The product's high-strength material is dustproof and vibration-resistant, suitable for long-term continuous industrial operation. Its rapid fuse response effectively protects precision DC instruments and control modules. Meanwhile, the manual reset function allows equipment to quickly resume operation after a minor fault, avoiding prolonged downtime caused by fuse replacement and effectively improving the operating efficiency of industrial equipment.

FAQ

Q1: Is this circuit breaker compatible with all DC systems from 12V to 48V? Can it be used in AC circuits?

A1: The Yiqi CB-01 is designed specifically for low-voltage DC systems, fully covering 12V-48V DC voltages, and can be adapted to most DC scenarios such as automotive, marine, and photovoltaic energy storage. This product is only suitable for DC circuits and cannot be used in AC circuits, otherwise the protection function will fail, causing safety hazards.

Q2: What is the difference between the manual reset version and the automatic reset version? What are the advantages of using them?

A2: The 12V-48V Waterproof Manual Reset Circuit Breaker does not have an automatic reset function and adopts a purely manual reset design. Automatic reset circuit breakers restore power automatically after a fault is cleared, but are prone to secondary damage due to transient, recurring faults. Manual reset, on the other hand, requires manual troubleshooting and confirmation of fault clearance before resetting, offering greater safety and controllability, and is particularly suitable for precision electrical equipment, outdoor power supplies, and other devices with high fault control requirements.

Q3: Does Yiqi support customized services and small-batch trial orders?

A3: Yes. Yiqi offers a full range of OEM services, including current parameter adjustment, brand logo customization, and packaging customization. For procurement, we support sample testing, small-batch trial orders, and large-batch customized procurement, providing customized supply solutions based on customer project scenarios. The brand has long-term partnerships with global distributors and importers, ensuring stable supply and flexible service.
