HD/HS Series Knife Switches Are Used For Circuit Isolation And Infrequent Operation
The HD and HS series knife switches (hereinafter referred to as switches) are suitable for use in power distribution systems operating at 50 Hz, with a rated operating voltage up to 690 V and a rated operating current up to 3000 A. They are used for infrequent manual circuit connection and disconnection, or as disconnectors.
The HD and HS series knife switches offer a compact design and flexible mounting options, allowing for vertical or horizontal installation, facilitating optimized layout within distribution cabinets. The blades maintain close contact, ensuring excellent conductivity and minimizing energy loss.
These switches offer excellent mechanical strength and thermal stability, making them suitable for industrial, commercial, and building power distribution systems, effectively enhancing the safety and reliability of electrical systems.

HR3/HR3BX Series Fuse-Type Knife Switches Are Used In Complete Power Distribution Equipment
The HR3/HR3BX series fuse-type knife switches are electrical devices that combine the functions of a fuse and a knife switch, primarily used in power distribution systems. They provide overload and short-circuit protection while allowing manual operation to connect and disconnect the circuit.
Key Features
- Fuse Protection: A built-in fuse automatically disconnects the circuit when the current exceeds the rated value, protecting it from overload and short-circuit damage.
- Knife Switch Operation: Manual operation of the knife switch allows for convenient connection and disconnection, making it suitable for applications requiring frequent operation.
- Applications for Power Distribution Systems: Designed for use in power distribution systems, they can be used in conjunction with other electrical components to form a complete power distribution system.
- High Reliability: Compact design, reliable operation, and stable operation in a variety of environments.
Application Scenarios
- Industrial Power Distribution Systems: Used to control and protect equipment such as motors and transformers in industrial environments such as factories and workshops.
- Commercial Building Power Distribution: Used in commercial buildings like shopping malls and office buildings to control electrical equipment such as lighting and air conditioning.
- Residential Power Distribution: Used in residential communities to control household electrical appliances and provide safety protection.
The HH15 series offers high thermal and dynamic stability, and its housing is constructed of flame-retardant material to effectively prevent fire hazards. The operating handle features an interlock function to prevent accidental operation and ensure safety.
Knife Switches are fundamental components in power distribution systems used for circuit isolation and infrequent operation. Chengxi's HD, HS series, and fuse-type knife switches HR3, HR3BX are designed for AC 50Hz systems with rated voltages up to 690V and currents up to 3000A. These switches are widely applied in industrial distribution cabinets and panels, serving as isolating switches or manual operation switches.
The product advantages include a simple structure and intuitive operation. The blade-type contacts provide clear breaking points, allowing easy visual inspection of the circuit status. Fuse-type models (HR3 series) integrate short-circuit protection, enhancing overall circuit safety. Constructed with high-conductivity materials and robust housings, these switches withstand large currents and exhibit high mechanical strength, making them suitable for industrial environments exposed to dust, humidity, and other harsh conditions.
Manufactured following standardized designs, the switches offer flexible installation options and convenient maintenance. They deliver reliable isolation and operational assurance within power distribution systems, making them indispensable basic components in industrial electrical distribution.
