Load Break Switch LBS Hefftron 100A 750VAC
Load Break Switches /Disconnector SwitchesHefftron 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.
They are commonly used for main switch, switch for motors, disconnectors and Safety switches according to IEC 60947-3
• 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.
