Cutler Hammer-Eaton LS-11-ZB Interlock Switch

The Cutler Hammer-Eaton LS-11-ZB Interlock Switch is a safety part to be installed in HVAC systems to avoid any unauthorized access to the systems. This interlock switch works in a manner that connects the movement of various HVAC system parts like fans and heating coils so that one cannot work while the other is not in its safe mode. For instance, a heating coil will not blow hot air until the fan that is coupled with it is on, to avoid overheating and subsequent damage. This is especially useful in commercial and industrial working environments in managing HVAC systems known to reduce the chances of equipment breakdown and accidents.
