PTC of MZ2 series is a million time safety device of automatic protection, recoverability, using repeatedly, and no trigger, noise or sparks
When PTC is in the normal state, the resistance is too low to affect the regular work
of the protected circuit such as the voltage transformer's primary and secondary loops
When the circuit is in disorder, the PTC will generate heat suddenly, and the resistance value will go up to the high state, which can make the circuit in the state of relatively breaking up to protect the circuit
Overload and current protection of mini voltage transformer primary loops, chargers, safety guard unit and thunder surging protection circuit of telecoms apparatus, and industry-controlling exchangers
Over-current protection of ammeter, digital multi-meter RS485 interface, micro-electricity machinery and transistor
