HEFFTRON Load Break Switches / Disconnector Switches are used for isolating loads during maintenance to make and
break under load conditions and provide safety isolation at the low voltage electrical circuits. Mainly suitable for AC 50Hz at rated voltage 415V with rated current up to 3150A.

They are commonly used for main switch, switch for motors, disconnectors and Safety switches according to IEC 60947-3.

GENERAL CHARACTERISTICS

• High electrical and mechanical indurance.
• Double break and self cleaning contacts.
• High breaking capacity (AC22/AC23).
• Independent manual operation.
• Neutral at full current as same as Phase contacts until 3150A.
• Direct padlockable handle in OFF position.
• Contact position can be indicated by the handle.
• Casing in self extinguishing are made by Glass fibre reinforced polyester.
• All of contact materials are copper alloy palted with silver plating.
