| Dear maddam or sir:
(sorry for interupting
you)
When traditional fuses being used for
overcurrent protection,they only can protect one time,once being
blown out they must be replaced,but the PTC resettable fuses
as the new type overcurrent protection products have the
double fountions of overcurrent protection and automatic
restoration.
Our PTC resetable fuse is serially
connected in the circuit,under normal circumstances it presents low
resistence state and can ensure the normal work of the circuit.In
case of occuring short circuit or unsually high current,the heat in
the fuse is strong enough to make its impendance increasing to limit
current very low,so playing the role for protecting the
circuit.After fixing the fault,PTC element will automatically
return to its low resistance state.
Compared to the traditional fuse,PTC
prossesses the advantages of resettable,little volume and
solidness.
Best whises for you !
您好!
深圳市万瑞和电子有限公司是一家专业生产高分子PTC自恢复保险丝的高新技术企业，公司拥有完整的质量保证体系，已通过ISO9001质量体系认证。同时公司产品也通过CE、长城、Tüv等多项认证和信息产业部通信产品防护性能质量检测。
万和自复保险丝串联在电路中，正常情况下呈低阻状态，当电路短路或串入异常大电流时，自复保险丝在很短时间内变成高阻状态，从而对电路起到保护作用，当异常消除后，自复保险丝又自动恢复到低阻状态，无需人为更换或维修。
有意者欢迎来电来信咨询、洽谈.
