Product Description

RB1 thermal bimetal strip A bimetal used for circuit breakers

Common Name: Truflex P675R,  Chace 7500, Telcon200, Kan  200)
Bimetallic RB1 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.
