LC7K Contactor – 4P, 4NO, 20A, AC-1, 230VAC coil

K-series 4-pole contactor with 4 normally open (4NO) power contacts, designed for AC-1 category circuits. The contactor features a 230VAC control coil, is rated for loads up to 440VAC and 20A in AC-1 mode, and can be used in various automation, control, heating, lighting, and other electrical circuits.

• Lighting control circuits – for group switching of light fixtures, lighting zones, or advertising signs.
• Heating systems – for controlling electric heaters, heating sections, or other resistive loads.
• Automation panels – for switching loads based on a signal from a relay, timer, PLC, or another controller.
• Commercial and industrial facilities – when multiple separate circuits need to be switched simultaneously.
• Building engineering systems – in ventilation, alarm, control, and other auxiliary electrical circuits, considering the load category.

For example, the contactor can be mounted in an automation panel where a 220–230VAC control signal from a timer, thermostat, switch, or controller activates the contactor's coil. Once the coil is energized, the four 4NO contacts close, simultaneously supplying power to four separate AC-1 category circuits.

This solution can be used for heating circuits, lighting zones, auxiliary loads, or other systems where centralized and automatic control of multiple circuits is required.

Electrician: A compact contactor suitable for installation in control panels, DIN rails, or other electrical distribution solutions. The four NO contacts allow for convenient control of several circuits with a single coil control signal.

Designer / Engineer: Suitable for systems requiring a 4-pole AC-1 contactor with a 220–230VAC coil. Before selection, it is essential to evaluate the load type, current, voltage, switching frequency, and the specific circuit's utilization category.

Maintenance Technician: Can be used to replace an identical code or equivalent parameter contactor in automation and control systems. When replacing, it is recommended to verify the contact configuration, coil voltage, and load category.

The contactor is an electrical control device; therefore, its selection and installation must be performed after evaluating the specific system load, utilization category, control voltage, and required protective measures.

• Installation must be performed by a qualified electrician.
• Before installation, disconnect power and check that there is no voltage in the circuit.
• Check the control coil voltage – this version is intended for 230VAC.
• Do not exceed rated parameters – up to 20A in AC-1 category and up to 440VAC according to specified operating conditions.
• For motor loads, it is necessary to separately evaluate AC-3 category, inrush currents, and motor protection.
• Use appropriate wire cross-sections, protective devices, and follow electrical installation requirements.

Quick selection guide

This is a suitable choice when four normally open power contacts and a 220–230VAC coil are needed for controlling AC-1 category circuits. It is particularly practical in automation panels, lighting, heating, and other resistive load control systems.
