Bilame with retractable insulation cap, high breaking capacity for insertion into the windings of rotating machines and transformers. Customized application in single, double, triple etc ...

Bimetallic design: PT0 / PTF

Insertion area: Sensor for insertion into the windings of rotating machines and transformers. 

The insulation of the U1 retractable cap can withstand a temperature of 200 ℃.

Compact and pressure-stable: Ideal for installation in a limited space, very suitable for mounting on and on windings.

Reliability and durability: constant contact pressure over the entire temperature range; Very fast switching, therefore little influence of arcing on the contacts.

Sensitivity to temperature: reproducible Switching temperature induced by a non-resistive and electrically discharged mechanical bimetallic disc.

Speed: Excellent thermal coupling induced by a compact switchgear.

Flexibility: Wide assortment of wires available for connection.

Air Vacuum Test Procedure - The bimetallic strips are placed in a sealed chamber. - The chamber pressure is reduced to 30 mbar. At this pressure and at a temperature between 18 and 25 ° C the bimetallic strips are immersed in a impregnating resin. Bimetallates are placed under these conditions during dry 60. - The pressure is then normally stabilized at 1 Bar. - 120 sec. later bimetallic strips are removed from the impregnating resin. After which the bimetallic strips will remain for 2 hours in an oven at a temperature of 120 ° C in order to harden the impregnating resin.
