3RT1466-6NP36

Description

Overview

The Siemens 3RT1466-6NP36 is a high-performance power contactor designed for industrial applications requiring reliable switching and control of electrical loads. Suitable for AC-1 operations up to 400 A and 690 V, it ensures optimal performance even at 40 °C ambient temperature. Its 3-pole configuration, combined with advanced electronic auxiliary contacts, makes it ideal for PLC-driven automation systems.

Key Benefit

• High Capacity: Handles up to 400 A at 690 V AC for heavy-duty industrial loads.

• Versatile Control: Supports both AC (200–277 V) and DC inputs for flexible PLC integration.

• Reliable Operation: 3-pole design ensures stable power switching.

• Efficient Monitoring: Electronic auxiliary contacts (2 NO + 2 NC) provide precise signaling for control systems.

• Durable Connections: Main circuit uses busbar connections, while control and auxiliary circuits use screw terminals for secure installation.

• Temperature Resistant: Performs reliably up to 40 °C ambient temperature.

Function

• Switching and control of high-current loads in industrial environments.

• Integration with PLC systems using 24 V DC input.

• Monitoring through auxiliary contacts for automation and safety purposes.

• Simplified installation via busbar and screw terminal connections.
