Temp-Sensing Protector

Product Specifications

Markets:	South America,Mid East

Product Description

Item no.: AH9
Panted product:
The integrated injection molding main structure is more reasonable and more compact.
Square silver contact with longer resistive and larger current-carrying capacity.


AH9 series is auto-reset temp-sensing protector,the snap-action of bimetal will cut off the circuit when pre-calibrated temp are reached,protecting electrical from fault condition, the bimetal will auto-recover to connect circuit as the temp drops to reset temp-rating


AH9 series divided into large & medium & small sizes according to different currrent-carrying capacity. There are metal & plastic cases for your choice, metal case are more sensitive to heating response and higher temp-resistanced campared by plastic case.
