Frequently Asked Questions

Q What is the difference between HD13BX and HD13 knife switches?

The HD13BX features a rotary (BX) operation mechanism, while the standard HD13 uses a lever operation mechanism. Both belong to the HD13 series of central lever operation open-type knife switches, but the rotary type offers more flexible panel mounting and operation angles.

Q What rated operational voltages are supported by the HD13BX knife switch?

The HD13BX knife switch supports a rated operational voltage of AC380V, with an insulation voltage of up to 1000V, making it suitable for standard industrial power distribution applications.

Q What current ratings are available for the HD13BX series?

The HD13BX series is available in the following conventional free-air thermal current ratings: 100A, 200A, 400A, 600A, 630A, 1000A, 1500A, and 2000A, covering a wide range of industrial load requirements.

Q Does the HD13BX knife switch come with an arc extinguishing device?

Yes. In the type designation, "0" indicates the switch is supplied without an arc extinguishing device, and "1" indicates it is equipped with an arc extinguishing device. Please specify the required configuration when ordering.

Q What pole configurations are available for the HD13BX knife switch?

The HD13BX knife switch is available in 1-pole, 2-pole, 3-pole, and 4-pole configurations. Dimension tables for 2P, 3P, and 4P variants are provided to assist with installation planning.

Q What is the mechanical and electrical endurance of the HD13BX switch?

Mechanical endurance ranges from 3,000 to 10,000 operations depending on the current rating. Electrical endurance (not applicable to central handle type) ranges from 100 to 300 operations. Higher current ratings generally have lower endurance cycles due to greater contact wear during operation.
