SY-6 / CY-6 ThermalProtectors for Star Connection
2Pages

rotectors (TP) of type Y6 with normally closed contacts are designed to protect small three-phase motors up to 700 VA (1.6A*440V) against overheating. The Y6-types can be placed between the windings of different phases because of their housing pressure stability and impregnation resistance. > The design of the Y6-types is based on the well proven mechanism of Thermik֒s product series 06 with three connection leads for a star point connection. Versions : SY6 - with insulation cap CY6 - without insulation cap > If - in the case of overheating - the rated switching temperature of the bimetal is reached, it suddenly snaps over and disconnects the two contacts and the contact- bridge. Now, each phase is disconnected from the other ones. Automatic reset immediately after a significant temperature drop. > Compact design with high pressure stability For star connection : to use without any relay Quick response sensitivity : featured by the metal housing and small protector mass Excellent long term performance : due to fine silver contacts. Reproducible switching temperature values due to tempered, mechanically and electrically unstressed bimetallic disc Very short bounce times : < 1 ms Instantaneous switching : with constant contact pressure over the whole temperature range. Minimal burning-off of the contacts Temperature resistance : by use of high temperature resistant materials and components > Thermik Gertebau GmbH ? P.O. Box 101980 ? D-75119 Pforzheim /Germany ?
