Siemens 3RT1 Series Contactor, 330A Operational Current, 1 kV Contact Voltage - 3RT1066-2AV36

This contactor is a three-pole switching device designed for controlling AC motors and heavy electrical loads in industrial automation environments. It provides a dedicated safety function and is suitable for applications requiring coordinated switching and auxiliary signalling within control systems.

Features and Benefits:

• 300A contact rating enabling high-current switching capability
• 160kW power rating for heavy-duty AC-3 motor duty
• 330A operational current for extended load handling
• 380/420V Coil voltage supporting common industrial supplies
• 2 NO 2 NC auxiliary contacts for flexible control circuits
• Spring terminals and DIN-rail mounting for Rapid installation

Applications

• Suitable for industrial motor starter panels in factories
• Ideal for safety-related switching in machine control cabinets
• Used with high-power AC drives requiring robust contactors
• Can be used for switching at elevated system voltages up to 1kV insulation

What environmental temperature range can it tolerate during operation?

It is rated to operate down to -25°C and up to 60°C, covering typical indoor and controlled-plant conditions.

How is the device mounted and wired within control panels?

It is designed for DIN-rail attachment and features spring-terminal connections for secure, tool-assisted wiring.

What standards underpin its safety-related design?

The unit conforms to recognised safety and ingress standards including IEC 60529, IEC 61508-2, ISO 13849-1 and ISO 13849-2.

How many poles does it switch and what is the insulation capability?

The device provides three switching poles and is specified for contact voltages up to 1kV.
