Product details about "10A miniature bimetallic strip with high breaking capacity"
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.
