Thermal Protector Type e6

Anwendung:

Thermal Protectors (TP) of version e1 with normally closed contacts are standard versions, utilised for overheating protection of all kinds of electrical equipments or devices, e. g. for electric motors, heaters and transformers. These TPs characterize their ability to tolerate higher current load in spite of their small design. Further to this, they can be installed into the windings because they are pressure- and impregnation resistant.

Aufbau:

These switches are equipped with a high capacity contact mechanism, wherein the bimetallic disc can move freely, without the current flowing through it. An additional spring disc maintains constant contact pressure until reaching its switching temperature. The version e6 has an epoxy coating for best thermal transfer to the housing. Therefore –when fitting – the base insulation of the switch is provided and does not need to be done by the customer. Onto the blue coloured insulation, the manufacturer logo, type, nominal switching temperature with its tolerance is marked.

Funktion:

If, in case of overheating, the rated switching temperature of the bimetallic disc is reached, it suddenly snaps over to open the contacts. After cooling down to the resetting temperature, the bimetallic disc resets and causes the contacts to reclose.

Merkmale:

Strong power density : strong currents in small types of construction Quick response sensitivity : featured by small protector mass and the metal-housing Excellent long term performance : due to instantaneous switching, fine silver contacts, constant contact resistance and to electrically as well as mechanically unstrained bimetallic disc, reproducible switching temperature values Very short bouncing times :
