ABB Fireman Switch
The fireman switch is a specialized switch disconnector/isolator. You can often see these switches on the outside wall of shops, industries or commercial buildings. They are used by firemen to turn off neon-lighting or other electrical equipment in case of fire to prevent the overheated equipment from exploding.
The enclosure is made of non flammable material and painted red to be easy to spot. The on & off positions are clearly indicated on the front side with I and O. The operating handle is designed in such a way that a fireman-hook or axe can be used to switch off. To reset a so called two hands grip must be used. The interlocking mechanism prevents accidental manoeuvres.
Robust & reliable design in non flammable material (Aluminum).
Operating handle locked in O position and a two hands grip to reset for safety reasons.
Easy to install and to operate. Possible to add on an auxiliary contact.
Complies with IEC 60947-3 and BS7671.
