At GRL, our fuse manufacturing is built on a philosophy of “high standards and strict requirements.” From the meticulous selection of raw materials to the final product leaving our facility, every step is rigorously controlled to ensure each item is worthy of your trust.

Precision Manufacturing & Automated Production Lines:

We’ve integrated globally leading automated production equipment and precision molds. This has enabled high-level automation for core processes like melt assembly, welding, and encapsulation. This not only significantly boosts production efficiency but also ensures every GRL fuse has exceptionally consistent dimensions, resistance, and performance, minimizing human error.

Rigorous and Comprehensive Performance Testing:

Before any GRL fuse leaves our factory, it must pass a series of tests that are even stricter than industry standards. These include voltage withstand tests, temperature rise tests, breaking capacity verification, and load cycle tests. We simulate various extreme application scenarios to ensure our products can reliably and instantly interrupt a circuit under overload and short-circuit faults, providing solid safety protection for your equipment.

Superior Core Materials:

GRL insists on using high-purity electrolytic silver or copper for the core melt. This guarantees a fast and precise response during a fault. Additionally, we use high-performance flame-retardant insulating materials and high-quality ceramic tubes to effectively contain the arc and ensure the product maintains excellent insulation and mechanical strength even at high temperatures.
