| Series | HS11FD |
HS11FD series switch was originally a knife type change-over switch, and then it was redesigned and improved into an error proof isolator with grounding function (hereinafter referred to as the switch), which added a mechanical locking mechanism, opening and closing signal output, grounding function and live indication function.
It effectively solved the technical problems of low-voltage switch grounding difficulty, hidden danger of closing with ground wire, and prone to safety accidents.
It has simple structure and convenient grounding, It can prevent the occurrence of switching on accident with ground wire and the occurrence of loaded broach switch accident.
The design state of this switch is divided into power on state and grounding state. This switch meets the requirements of standard GB14048.3-2008.

Due to the addition of live indication function to this series of switches, there are phase sequence requirements for power supply in the internal circuit.
Please indicate that the zero line (N pole) is on the left or right side when ordering, and also indicate the current level, wiring mode and quantity.
Please consult our technical department for special orders. For example: HS11FD-200/481 N pole is on the right side of 10 sets.
