產品描述

MZ2系列PTC熱敏電阻器MZ2 SERIES PTC THERMISTOR

用於過流保護For Over-current Protection

產品特點FEATURES

MZ2系列PTC是一種自動保護，自動恢復，反復使用，無觸點，

無噪音，無火花的“萬次保險器”。

PTC of MZ2 series is a million- time safety device of automatic protection,

recoverability, using repeatedly, and no trigger ,noise or sparks.

當PTC處於常態時，阻值很小，不會影響到變壓器初、次級線

圈等被保護電路的正常工作。

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.

當電路出現故障時，PTC陡然發熱，阻值聚增至高阻態，使電路

處於相對“斷開”狀態，保護電路。

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.
