Product Description

TB20110/BR-1/RB-1/NLY Thermal Mn72ni10cu18/Ni36 Bimetallic Strip For Breaker 

Product Description

Common Name: Truflex P675R, Chace 7500,Telcon200

Bimetallic 5J20110 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.
