SR250 series

SR250 series

SR250 series PTC thermistor has the rated working voltage of 250V and rated maintenance current of 0.08A-0.06. As an over-current protector specially designed for switchboard and distributing frame, it is advantaged by small room temperature resistance, high reliability, and convenient installation, the use available in an environment at 60DEG C or above, and automatic restoration and reuse after faults in circuits are eliminated. Proved through random inspection by Test Center for Protective Products of Ministry of Information Technology and Telecommunications (former Ministry of Posts and Telecommunications) and State Bureau of Technical Supervision (CSBTS) many times, its performance completely conforms to standards of the posts and telecommunications industry.
