Thermal Cutout also known as Self-Resetting Thermal Protection Cut-outs Model BPM has been developed by our engineering department after extensive R&D for over temperature and burn out protection of all electrical and electronics equipment. It is the smallest thermal cutout in our entire range of thermostats. Due to its small size, this thermal cutout is very sensitive to temperature rise and current overload.

This thermal cutout has a bimetal strip and a beryllium copper blade and the operating mechanism is based on the snap action disc thermostat. Due to this there is quick make and break switching and there is no sparking when the it switches on or off. The internal contacts are made of solid silver to ensure long life of 1,00,000 operations. The outer body of this thermal cutout is a high temperature resistant engineering polymer. The internal construction of this thermal cutout is all spot-welded on a stainless steel housing plate. The wires are Teflon lead wires, which can take high temperature. The body of this thermostat is sealed and resistant to dust, dirt, fumes, moisture, gases etc. Due to the small size the response to temperature rise is fast, thereby ensuring complete thermal overload protection during rapid temperature increase.

This thermal protection cutout is available with Normally Open (N.O.) or Normally Closed (N.C.) contacts.
