Introduction Circuit overload,...
Introduction
Circuit overload, short circuit and leakage are the main causes of power equipment damage and electrical safety accidents in low-voltage power distribution systems. Relying on years of low-voltage electrical R&D experience, Xinglihui Electric provides a complete set of circuit safety protection solutions through Circuit Breaker series and Fuse series, matching the switching products to form a full-link safe power distribution system.
Our Circuit Breaker series includes molded case circuit breakers and residual current circuit breakers, integrating overload, short-circuit and leakage protection functions, with sensitive response and stable breaking performance. The Fuse series adopts high-precision melt core design, which can quickly cut off the circuit under overcurrent conditions. The two series of products cooperate with switching equipment to realize dual protection of low-voltage power circuits, widely used in urban and rural power grids, power stations, industrial and mining enterprises and other scenarios.
Core Product Advantages
Circuit Breaker series: Fast tripping response speed, accurate current identification; anti-aging insulating shell, strong resistance to external interference; modular design, easy for installation, replacement and later maintenance.
Fuse series: Precise overcurrent triggering, stable fusing performance without false action; plug-in anti-loose structure to avoid poor contact; high safety factor, effectively prevent circuit burnout and fire hazards.
FAQ
Q1: What is the respective application scenario of circuit breakers and fuses?
A: Circuit breakers are reusable protection devices, suitable for long-term power distribution circuits that require frequent power-on and power-off, and can automatically reset and work normally after troubleshooting. Fuses are one-time protection devices, mostly used for branch circuit precision protection and terminal equipment safety protection, with lower cost and more sensitive overcurrent protection.
Q2: Will your molded case circuit breakers fail in high-temperature working environment?
A: No. Our circuit breakers adopt high-temperature resistant insulating materials, and have passed strict high-temperature aging tests. They can maintain stable protection performance in conventional high-temperature industrial environments and outdoor power grid operation scenarios, with low failure rate.
Q3: How to choose the right current specification for fuses and circuit breakers?
A: It is mainly matched according to the actual load current of the project. For conventional civil power distribution, small current specifications are applicable; for industrial mines and oil field equipment, high-current heavy-duty models are recommended. Our technical team can provide free parameter selection guidance according to customers’ project scenarios.
Q4: What is the delivery cycle for bulk orders of protection series products?
A: We have complete spot inventory of conventional specifications, with fast delivery within 3-7 working days. For customized products and large batch engineering orders, we will arrange production scheduling preferentially and ensure on-time delivery according to the contract cycle.
