Product Structure Features
Simple and compact structure, unique and innovative, modular functionality, and modular assembly;
The coil is encapsulated in plastic, with advanced technology, beautiful appearance, high insulation strength, and high mechanical strength;
CJ35-09-95 has strong versatility, and accessories such as auxiliary contact groups, air delay heads, and mechanism interlocks can be installed on all five sides except for the bottom surface;
The arc extinguishing hood is made of high-strength plastic compression, with high mechanical strength and good arc extinguishing performance. It is also fixed by a locking rod rotating compression spring, which is convenient and reliable.
The CJ35-40-95 contactor has a large number of auxiliary contacts and is easy to replace. It comes with one normally open and one normally closed auxiliary contact, and can also be equipped with an auxiliary contact group. There are a total of six pairs of auxiliary contact groups available for selection. The CJ35-115-780 contactor coil is equipped with a dedicated auxiliary contact for self-locking or DC control conversion, and can also be equipped with two sets of auxiliary contacts, totaling 8 pairs of auxiliary contacts. The installation of the auxiliary contact group does not require screws to fix, just push along the guide rail and hear a "click" sound. If an air delay head is needed, it can be directly used to replace the auxiliary contact group;
The contactor has a significant energy-saving effect, and CJ35-400-780 is controlled by AC input direct charging;
The interlocking mechanism of the contactor is simple and reliable, and can interlock two units horizontally; CJ35-115-630 can also achieve two vertical interlocks and three vertical interlocks.
