TeSys D power contactor AC3 80A 3P 1NO 1NC 220VAC coil screw terminals LC1D80M7

Power contactor for controlling motors and circuits

This three-pole TeSys D power contactor with a rated current of 80A is a reliable solution for frequent switching of loads such as electric motors, heating systems or lighting. It is suitable for both industrial and commercial applications. The contactor design is designed for easy installation and long-term operation.

Construction and characteristics

The LC1D80M7 contactor features screw connections for both main and control circuits. It has built-in auxiliary contacts – one normally open (1NO) and one normally closed (1NC) – eliminating the need for additional contactor blocks in many applications. This saves space and simplifies wiring. Made of high-quality materials, it guarantees mechanical endurance of 15 million switching cycles and a high switching frequency – up to 3600 cycles per hour. A wide range of coil voltages allows the contactor to be adapted to different control systems.

Applications and benefits

The TeSys D contactor is a versatile device that finds application in:

• Motor starters: Direct starting of three-phase motors with a power of up to 37 kW at 400V.
• Heating, ventilation and air conditioning (HVAC) systems: Controlling heating and cooling loads.
• Industrial automation: Switching on and off various electrical devices in production lines.
• Commercial buildings: Controlling lighting, ventilation systems and other electrical devices.

Benefits for the installer:

• Easy installation thanks to screw connections and compact design.
• Built-in auxiliary contacts reduce the need for additional components.
• Wide range of coil voltages makes it easy to adapt to existing control systems.
• Compliance with many standards (IEC, UL, CSA, CCC, EAC, Marine) ensures versatility of application.

Benefits for the end user:

• High reliability and durability ensure long-term operation without failure.
• Protection against overload and short circuit protects the electrical installation.
• Compact dimensions allow mounting in limited space.
• Green Premium compliance guarantees an ecological approach to production and device use.

Key contactor parameters:
