Description: The large area silver contact has low temperature and long service life. The iron core sucks and closes smoothly, does not deform due to sucking and shock, and it has a mechanical life of ten million level. More than 5000 turns copper wire coil winding guarantee stability. Featuring exquisite workmanship, this AC contactor is safe to use. Featuring the hardened alloy spring that can rebound strongly and rapidly, this AC contactor has good working efficiency. With silver contact type high conductivity copper parts, it can efficiently reduce the chance of sparks, and it has the merits of low heat, stable performance, antioxidation and durable. The shell adopts flame retardant material, and the contactor is equipped with a dust-proof transparent cover, which can avoid suction failure caused by dust blockage. Made of high-quality ABS and metal, this AC contactor has the merit of durable and fireproof. The length of this AC contactor is 8cm, the width is 4cm, the height is 7.5cm. It is suitable for electric motor, capacitor bank, electric equipment, etc. Item Name: AC Contactor Material:ABS,Metal Ambient Temperature: -5 Celsius Degree - 40 Celsius Degree Rated Voltage: 690V Rated Current: 18A Mechanical Life: 3600 (Million Times) Main Contact Form: Silver Contact Auxiliary Contact Type: Silver Contact Working Elevation: 2000m Air Extinguishing Medium: Air Type Number of Main Contact Poles: 3 Poles Main Contact Control Circuit: AC Contactor Number of Normal Open Main Contacts: 3 Coil Voltage: 1:24V, 2: 36V, 3: 48V, 4: 110V, 5: 220V, 6: 380V Number of Poles: 3 Coil Frequency: 50/60Hz Heating Current: 32A Electrical Life: 1200 (Million Times) Size:8cmx4cmx7.5cm/3.15inx1.57inx2.95in Notes: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. The coil voltage is not the main contact voltage, the nameplate marks the coil working voltage. For example: the voltage of the coil is 24V, then A1.A2 can not connect to a circuit other than 24V voltage, the wrong connection will cause the coil to not work or burn the coil. Package Includes: 1 X AC Contactor 1 X Chinese Manual
