Open Type Knife Switch

The HD13BX series is designed for low-voltage power distribution systems that require reliable manual connection, disconnection and isolation. It is commonly used where circuits are operated infrequently but must provide clear mechanical separation for maintenance and safety.

With multiple pole configurations, broad rated-current coverage and flexible operating mechanism options, this open-type isolation switch is suitable for photovoltaic systems, energy storage equipment, electrical grid cabinets and industrial distribution panels.

• Manual switching solution for low-voltage distribution equipment.
• Used for infrequent connection, disconnection and isolation of power supply circuits.
• HD13BX series supports rotary operation; lever-operation versions are also available by model selection.
• Rated current options cover 100A, 200A, 400A, 600A, 1000A, 1500A, 2000A and 3000A.
• Pole options include 1P, 2P, 3P and 4P configurations.
• Optional isolation cover and front or back wiring arrangements support different cabinet layouts.
• Designed to improve personal safety protection and reduce accidental electric shock risk.
• Applicable to photovoltaic, energy storage, power grid and industrial electrical systems.
• Complies with GB/T14048.3 and IEC60947-3 standards.

• Photovoltaic power distribution and isolation cabinets
• Energy storage system power distribution panels
• Low-voltage electrical grid distribution equipment
• Industrial power supply isolation and maintenance circuits
• Manual incoming, outgoing and feeder isolation positions
• Switchgear and control cabinet projects requiring visible mechanical operation

Select the switch according to rated current, pole number, operating mechanism, wiring direction and whether an isolation cover is required. For higher current models, confirm cabinet space, busbar connection dimensions and operating handle clearance before production or installation.

• Confirm the rated current and short-time withstand requirement for the circuit.
• Choose 1P, 2P, 3P or 4P according to the protected and isolated conductors.
• Match the front or back wiring arrangement to the cabinet busbar layout.
• Installation and operation should be performed by qualified electrical personnel.

The HD13BX series provides a practical manual isolation solution for low-voltage distribution projects that require high-current capability, visible operation and flexible installation choices. Its broad current range and multiple mechanism options make it suitable for both standard electrical panels and renewable energy distribution systems.

When requesting a quotation, please provide the rated current, pole number, operating mechanism, wiring method, isolation cover requirement and installation dimensions. For project selection, include the cabinet layout and busbar arrangement so the correct model can be matched.
