• Global Recognition: Siemens is a trusted brand, ensuring product availability and support worldwide.

Protection and Connection:

The 3RT2325-1AF00 emphasizes comprehensive protection. All connections (main, auxiliary, control) must be safeguarded against overload and short circuits. For detailed guidance on protection for free-standing contactors or device combinations (e.g., with overload relays or circuit breakers), refer to Siemens’ technical product data sheets and configuration manuals. Overvoltage protection for the control supply voltage can be achieved by retrofitting with optional surge suppressors (RC elements, varistors, diodes), which are available as accessories.

Connection Methods:

• Main Circuit: Screw terminals are provided for secure main power connections.
• Auxiliary and Control Circuit: Screw terminals ensure reliable connections for auxiliary and control wiring.

Motor Protection:

While primarily for AC-1 applications, the 3RT2325-1AF00 can be combined with Siemens 3RU2 thermal overload relays or 3RB3 electronic overload relays for robust motor protection against overload.

Operating Mechanism:

This contactor features a conventional AC operating mechanism, controlled via the A1-A2 terminals with a 110 V AC, 50 Hz supply. The solenoid coil is replaceable, extending the lifespan of the unit.

Accessories and Spare Parts:

Expand the functionality of your 3RT2325-1AF00 with a wide range of SIRIUS accessories, including additional auxiliary switches, surge suppressors, and various spare parts. Consult the Siemens Accessories and Spare Parts for SIRIUS 3RT2 contactors catalog for a complete list.

Application

The Siemens 3RT2325-1AF00 contactor is ideally suited for:
