过流保护PTC热敏电阻器

MZ2系列PTC热敏电阻器MZ2 SERI PTC THERMISTOR

  用于过流保护For Over-current Proteion

产品特点FEATUR

MZ2系列PTC是一种自动保护，自动恢复，反复使用，无触点，

无噪音，无火花的“万次保险器”。

PTC of MZ2 seri is a million- time safety device of automatic proteion,

recoverability, using repeatedly, and trigger ,ise or sparks.

当PTC处于常态时，阻值很小，不会影响到变压器初、次级线

圈等被保护电路的正常工作。

When PTC is in the rmal state, the ristance is too low to affe the regular work

of the proteed circuit such as the voltage transformer’s primary and secondary loops.

当电路出现故障时，PTC陡然发热，阻值聚增至高阻态，使电路

处于相对“断开”状态，保护电路。

When the circuit is in disorder, the PTC will generate heat suddenly, and the ristance value will go up to the high state,. which can make the circuit in the state of relatively “breaking up” to prote the circuit.
