AC contactor is an electrically controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch. AC contactor is one of the most commonly used low-voltage control appliances in power drag and automatic control systems. As an executive element, it is used to connect and disconnect lines, or to frequently control the operation of electric motors and other equipment. It is composed of moving and static main contacts, arc extinguishing cover, moving and static iron cores, auxiliary contacts and bracket shells.
Timelec AC contactors meets IEC 60068-1, which are designed with Compact Design and has wide range of models, offering the safest electricity protection.
Product Fetures
| Extra long life:Series B contactors have been tested and verified to withstand 100,000 full-load on-off times under AC-a load class. | ||
| Ultra-mute:The B series eliminates the obvious impact sound of the traditional contactor at the moment of suction and closure, and eliminates the low-frequency hum of the contactor in operation. Applicable to the vast majority of building electrical field. In particular, the AC/DC series has achieved zero noise, creating a very quiet environment for you. | ||
| Super Energy Saving:Series B contactor to optimize the electromagnetic system, greatly reducing the contactor to maintain power. | ||
| Ultra-small volume:B series contactor width is much smaller than the traditional contactor, more saving the installation space of users, can be easily installed in the general distribution box. | ||
| More accessories:The B series contactor can be extended to connect the auxiliary contact on the right side of the product, which is more suitable for the signal feedback requirement in the intelligent control environment. |
