HD(HS) Series Open-Type Knife Switches and Knife-Type Changeover Switches

Scope of Application

• The HD series and HS series open-type knife switches and knife-type changeover switches (hereinafter referred to as “switches”) are suitable for AC 50Hz and rated operational voltage up to 690V, rated voltage up to AC 690 V and rated current up to 3000 A. They are used for infrequent manual making and breaking of AC circuits or as isolating switches.
• Central handle type switches are mainly used in power stations and power distribution systems as isolating switches without interrupting current-carrying circuits.
• Central lever-operated mechanism switches are mainly used in switchgear cabinets designed for front operation and rear maintenance, with the operating mechanism installed on the front.
• Side-front lever-operated mechanism switches are mainly used in switchgear cabinets designed for side-front operation and front maintenance, the operating mechanism can be installed on either side of the cabinet.
• Switches equipped with arc chutes can interrupt load currents; other series of knife switches are used only as isolating switches.
• This product complies with IEC 60947-3 and GB/T 14048.3 standards.

Normal Service and Installation Conditions

• Ambient air temperature not higher than +40 °C and not lower than -5°C.
• Installation altitude not exceeding 2000 m.
• Humidity: At a minimum temperature of -40°C, the relative humidity at the site shall not exceed 50%. Higher relative humidity is permitted at lower temperatures (e.g., 90% at 20°C). Appropriate measures shall be taken against occasional condensation caused by temperature variations.
• Pollution degree of the surrounding environment is degree 2.
• The switch shall be installed in a location free from significant vibration, shock vibration and rain/snow exposure. The installation site shall be free from explosive media, and the medium shall contain no gases or dust sufficient to corrode metal or damage insulation.
