Available from Kraus & Naimer , the KG switch series is mainly used as motor and industrial panel disconnectors, double-throw transfer switches, safety switches, main disconnect switches and distribution system isolation switches.
The KG1 0A through KG317 switch line offers excellent performance characteristics and exceeds the requirements of IEC 60947-3 as well as the new VDE 0660 part 107.
KG's modular switches offer maximum flexibility in carrying out modifications in the field. Modules can easily be added to switches already installed in equipment, often without having to remove existing wiring. The modular design also minimises the need for maintaining high inventory levels.
KG series switches offer high short-circuit withstand capabilities with positive contact movement during making and breaking functions. The switches exhibit excellent AC-3 and AC-23 making and breaking capabilities providing an additional safety advantage.
Safety features incorporated into the design of the KG switch series surpass those of many international standards organisations and include positive contact movement during making and breaking operations, higher dimensioned air and creepage distances for 690 V or 1000 V as well as dead front, ﬁnger-proof box terminals according to EN 50274, VDE 0660 part 514 and BGV A3.
Switch types KG210, KG250 and KG315 require an optional protective cover.
KG switches offer significant advantages during mounting and wiring with switch terminals provided on the same plane as the power conductors for ease of installation. The KG10A through KG105C base mounted switches feature a two hole mounting as well as a ‘quick mount’ design for standard DIN rails according to EN 50022. KG125 through KG317 feature a four hole mounting.
Accessories such as make before break auxiliary contacts, additional box and bolt terminals, shaft extensions, door clutches, terminal covers and padlock devices enhance the flexibility and versatility of KG’s proven line of switches.
