1 General

JFD16 load switch is one of the new products researched and developed independently by JUCHE Group according to the market demand. JFD16 series products are in conformity with standards GB14048.3 Low-voltage switchgear and controlgear - Part 3:Switches, disconnectors, switch-
disconnectors and fuse-combination units, IEC60204 manual switch-disconnectors, the mechanical operation also is in accordance with requirements of standards.

2 Scope of application

JFD16 series products are applied circuit of AC 50Hz/60Hz, rated norking voltage up to 380V~440V and rated working current up to 25A~125A, it can be used to control the three-phase or three-phase four-wire main circuit or auxiliary circuit. It also can be used to disconnect the three-phase motor or
other load equipment during maintenance. It can use three locks at most in breaking position.

5 Structure and features

5.1 Small volume, compact structure, stable performances, long service life.
5.2 Finger shield function, prevents from electric shock caused by contacting live parts accidentally.
5.3 This product possesses advanced new type motion mechanism, which guarantees high breaking and
making capacity of contacts. All contacts have self-cleaning function during the process of making and
breaking, and the long breaking distance of contacts sharply improves the reliability of switch.
5.4 Products of (3+N) three-phase four-wire (with auxiliary contacts, normal close) prevent electric shock
caused by electric leakage. This auxiliary closes in advance and breaks with lag, which guarantees safety for
load equipment and operators.
5.5 This series of products has both panel installation type and base installation type, the latter also contains
screw type installation and guide-rail installation of 35mm.
5.6 Universal joint connecting mechanism between the main body of lengthened transmission bar switch and knob handle has an eccentric distance
5mm that surrounds the axle center as well as a regulating distance of 5mm in axial direction, which enables the base installation type has strong adaptability.
5.7 This product can be equipped with indoor or outdoor used insulated box, the box body contains general steel sheet type or stainless steel type that has strong corrosion resistance, and hot moulding type that has strong impact resistance. Ingress protection of the product is IP40~IP65.
6 Installation conditions

6.1 The switch should be installed in places where the class of pollution is 3;
6.2 The switch should be installed according to the operation instruction provided by our factory.
