MK Electric Isolator Switch
MK switch-isolators
are uniquely designed to be compact and neat in appearance — coupled with MK’s renowned standard of quality, this allows the product to be placed unobtrusively in any outdoor location, no matter how exposed it is to the harsh effects of extreme heat, dust, rain and humidity. The polycarbonate front cover has been deliberately chosen to withstand the rigours of outdoor environments.
Rigorously tested
MK switch-isolators are manufactured according to the strictest MK quality standards and the ISO 9000 quality system requirements. All models are weatherproof as per IP66 and tested to IEC 60947-3 and BS EN 60947-3. An important point to note is that MK switch-isolators are independently tested by renowned independent test authority, besides our own in-house testing
Easily installed
Easy installation is one of the key features and benefits offered by MK. Cable entry knockouts are provided at the top and bottom of the enclosure. They are suitable for use with any standard range of cable/conduit accessories. Each unit is supplied with two adaptors for convenience of installation. Caps for mounting screws are supplied so as to enhance the weatherproof feature. Screw caps are also provided to prevent dust from collecting in the screw recesses and are designed to flush with the surface giving a good aesthetic look of a screwless switch-isolator.
Application
Designed to IEC 60947-1 & 60947-3, the MK range of switch-isolators are suitable for purpose of: • Isolating; • Switching ON & OFF on-load; • Emergency switching; • Functional switching It is designed for frequent switching even on severe load such as switching of motor loads or other highly inductive loads. Suitable to be mounted indoor and outdoor for adverse environmental condition of pollution degree 3 and IP 66.
Safety and security
To meet safety requirements of wiring installation rules, the handle can be padlocked in the switch OFF position for controlling equipment that are remotely installed. This will ensure securing an Off-load isolation against any inadvertent and unauthorised operation. There is also the option for padlocking in the ON position just by drilling a hole in the lever. Full instructions are provided in instruction sheet. A first and innovative design that allows padlocking to be done using padlock with hasp of smallest diameter up to 7mm
2-Pole and 4-pole construction
To ensure isolation of all live supply conductors from the circuit concerned, all poles are isolated. In addition, the isolating distance complies to requirement of IEC 60947 and that the position of contact is clearly and reliably ndicated
