CJX1-32 (3TB44) AC contactor Operating voltage 220V 380V 110V 72V 36V 42V 24V
CJX1 series AC contactor
One: the scope of application
CJX1 series AC contactor for AC 50Hz or 60Hz, voltage to 690V, current to 475A power lines for long-distance frequent start and control the motor and connected to the circuit. After the installation of mechanical interlocking mechanism composed of CJX1 series reversible contactor, can control the motor starting, stopping and reversing.
Two models and their meanings
Need to note that the normally open normally closed contact is generally 0,1,2 three, so with up there are 00,10,02,11,22 and so on, so the corresponding product model is also very much.
Common models are available
CJX1-16 / 22 (3TB4022); CJX1-12 / 22 (3TB4122); CJX1-16 / 22 (3TB4222); CJX1-22 / 22 (3TB4322)
CJX1-32 / 22 (3TF44 22); CJX1-45 / 22 (3TF46 22); CJX1-63 / 22 (3TF47 22); CJX1-75 / 22 (3TF48 22)
CJX1-140 / 22 (3TF52 22); CJX1-110 / 22 (3TF52 22); CJX1-140 / 22 (3TF51 22); CJX1-170 / 22 (3TF52 22)
CJX1-2000 / 22 (3TF53 22); CJX1-250 / 22 (3TF54 22); CJX1-300 / 22 (3TF55 22); CJX1-400 / 22 (3TF56 22);
CJX1-475 / 22 (3TF57 22);
Three: structural characteristics
CJX1 AC contactor for the double break point direct-acting structure, with three pairs of normally open contacts, auxiliary contacts up to 2 normally open, 2 normally closed. The contact support and the armature are connected by a flexible latch to eliminate the weak links. In the contact support or arc cover with a test rod, easy to operate manually and as an action indicator, Ie ≤ 22A contactor without interrupting arc plate, Ie ≥ 32A for the plastic arc cover and equipped with metal arc board. The contact material is made of silver alloy with high resistance to weldability and corrosion resistance. Threaded screw with a new self-starting screw, tile-shaped pad and screw parts immediately save wiring time. Full range of products can be installed with screws, Ie ≤ 32A products can also be fast embedded rail fastening.
Four: the main technical parameters
1. Products meet the IEC60947, BS5424 and GB14048.4-2003 and other standards.
2. The main performance is shown in Table 2
3. Life is shown in Table 2
4. The main technical parameters of the auxiliary contact are shown in Table 1
5. Rated control of the contactor The standard value of the supply voltage (Us) is AC (50Hz) 36V, 127V, 220V, 380V
6. Contactor in the rated power supply voltage of 85% -110% (hot) should be able to reliably pull the release of the voltage in the range of 20% -75%.
CJX1 AC contactor is mainly used for AC 50HZ (or 60HZ), rated insulation voltage of 690V, in the AC-3 category under the rated operating voltage of 380V rated current to 95A circuit for remote connection and breaking circuit , And with the appropriate thermal overload relay composed of electromagnetic starter to protect the circuit may be overloaded.
