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.
