Product Description

TB 20110/5J20110/P675R Thermal Bimetal Strip for Miniature Circuit Breaker
Common Name: Truflex P675R,  Chace 7500, Telcon200
Bimetallic 108sp holds very high thermal sensitivity and higher resistivity,but the modulus of elasticity and allowable stress is lower,it can improve the sensitivity of the instrument,decrease the size and increase the force.
