rotectors for Star Connection Type Y6 – Version SY6, CY6

Application:

T

P

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.

Design:

The design of the Y6-types is based on the well proven mechanism of Thermik’s product series 06 with three connection leads for a star point connection. Versions : SY6 - with insulation cap CY6 - without insulation cap

Operation:

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.

Features:

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 :
