TeSys K power contactor AC3 16A 3P 1NC 230VAC coil screw terminals LC1K1601P7

Power contactor for controlling motors and loads

This three-pole TeSys K power contactor with a rated current of 16A is a reliable solution for controlling AC-3 motors up to 7.5 kW (at 400V) and non-inductive AC-1 loads up to 20A. Its compact design (45 mm wide) allows for easy mounting on DIN rails or directly with screws. The contactor is equipped with a 230VAC coil, making it compatible with most standard installations. An additional 1NC auxiliary contact expands its application possibilities in control and signaling circuits.

Construction and practical application

The TeSys K contactor is designed for durability and efficiency. Its robust construction ensures a long service life, even with intensive use – it withstands up to 1.3 million electrical operating cycles. The rated operating current for AC-4 is 6A at a power of 2.2kW, allowing it to be used in applications requiring frequent switching of motors on and off. Connection is made using screw terminals, accepting wires with a cross-section from 0.34 mm² to 4 mm², which simplifies installation and ensures a secure connection.

Key features and benefits

• Compact dimensions: A width of only 45 mm saves space in control cabinets. This is especially important when designing new installations or modernizing existing ones.
• High reliability: Designed to operate in standard environmental conditions (up to 50°C) and with switching frequencies of up to 600 cycles per hour.
• Versatility: Suitable for controlling both AC-3 motors and non-inductive AC-1 loads.
• Built-in auxiliary contact: Enables the implementation of additional control functions without the need for additional elements.
• Compliance with standards: Meets the requirements of many standards (IEC, UL, CSA, CCC, EAC), which guarantees safety and compatibility with various systems.
• Safety: Rated impulse withstand voltage is as high as 8kV and the overvoltage category is III - a high level of protection against interference.
• Durability: Mechanical endurance at 10 million cycles ensures long-term use without the need to replace the device.
• Cost optimization: The miniature size combined with parameters similar to larger series contactors allows for reducing investment costs without losing functionality.
