Product Description

Paragraph 1

With 42 years of experience in low-voltage electrical equipment manufacturing, our factory specializes in producing Indoor load isolation switch (HS series load isolation switch) for safe power distribution and industrial applications. Different from fuse knife switches, this Indoor load isolation switch supports load switching operation while providing visible isolation protection. It features silver-plated copper conductive blades, enclosed arc extinguishing chambers, and stable switching performance, covering rated currents from 100A to 630A. The compact structure effectively reduces arc hazards during operation and is widely used in low-voltage switchgear, industrial power distribution systems, and equipment control cabinets.

Our 36,000㎡ standardized production facility integrates copper stamping, insulation injection molding, and assembly lines. Every switch undergoes strict inspection including material testing, temperature rise testing, insulation withstand testing, and mechanical operation testing. All products comply with IEC60947-3, RoHs2.0, REACH, and ISO14001 requirements. With reliable load switching performance and long service life, our Indoor load isolation switch is widely supplied to overseas electrical distributors and low-voltage system integrators.

Paragraph 2

For global switchgear manufacturers, electrical distributors, and engineering contractors, we provide complete OEM/ODM customization services for Indoor load isolation switch. Customers can customize current ratings, installation dimensions, handle positions, and appearance according to technical drawings or cabinet requirements. Sample development is available for project testing, and mixed models can be combined in one order.

Each switch includes an 18-month warranty after shipment. Our electrical production capacity reaches 50,000 sets per month, with standard models available in stock. Regular products can be shipped within 5 working days, while customized specifications can be completed within 7-15 days. We provide one-stop services including product customization, manufacturing, export packaging, and technical support for global customers.
