Frequently Asked Questions (FAQ)

What does the "HS" and "BX" prefix designate?

"HS" stands for Double-throw Transfer Knife Switch. The "BX" code specifies that the mechanism uses a rotary operation mechanism, whereas models without "BX" employ a standard lever operation.

What current ratings are supported by the HS13 series?

The HS13 transfer switch series supports wide-ranging conventional free-air thermal current ratings, including 100A, 200A, 400A, 600A, 1000A, 1500A, 2000A, and up to 3000A (2500A).

What pole options are available for installation?

The switch is available in 1-pole, 2-pole, 3-pole, and 4-pole configurations to fulfill varied power distribution and transfer requirements.

Does the switch come with an arc extinguishing device?

Depending on the model designation suffix, code "0" indicates units without an arc chute, while code "1" indicates the unit comes fully equipped with an integrated arc extinguishing device.

What environmental conditions are required for safe operation?

Operating temperature must remain between -5°C and +40°C, altitude under 2000m, and humidity up to 50% at +40°C. The switch must be installed in Level 3 pollution conditions free from rain, snow, severe vibrations, or corrosive and explosive gases.
