AC Contactor CA2-SKE 2 NO + 0 NC alternate 10 A 220 V AC

The CA2-SKE 2 NO contactor from Schneider Electric belongs to the TeSys range, a line renowned for its high quality and reliability in circuit control. This contactor is ideal for applications in control circuits, particularly in the AC-15 and DC-13 utilisation categories, which are often used in the switching of electromagnetic loads, such as contactors and solenoids in machine control and automation systems.

This model is equipped with 2 normally open (NO) contacts, allowing its use in various control applications where circuit switching is required under alternating or direct current conditions. With a conventional thermal current of up to 10 A at an ambient temperature of 55 °C, the CA2-SKE can handle the load without compromising operational efficiency. For additional protection, the use of associated 10 A type gL fuses is recommended, in accordance with VDE 0660 and IEC 60947 standards, ensuring adequate protection against overloads and short circuits.

The CA2-SKE is compatible with a rated operational voltage of up to 690 V AC at a maximum frequency of 400 Hz, making it a versatile option for different types of electrical installations. Its design allows operation with a control circuit at 220 V AC at 50/60 Hz, facilitating its integration into standard electrical control systems in many regions of the world.

The contactor has a compact design with dimensions of 58 mm in height, 45 mm in width, and 68 mm in depth, and weighs just 0.132 kg, making it easy to install in confined spaces without compromising performance. This device can be mounted on both DIN rails and plates, offering great flexibility when integrating into electrical panels or control cabinets.

One of the standout features of the CA2-SKE contactor is its high durability. With a mechanical durability of up to 10 million cycles, this device can withstand long periods of operation without requiring constant maintenance. Additionally, it has an operational range of up to 1200 cycles per hour, making it suitable for repetitive or high-frequency switching applications.

The contactor's performance is also outstanding in terms of energy efficiency. It has a inrush consumption of 23 VA at 20 °C and a holding consumption of only 4.9 VA, contributing to greater operational efficiency and reducing long-term energy costs. Furthermore, the device's heat dissipation is only 1.5 W, helping to maintain optimal operating temperatures and prolonging equipment lifespan.
