• Cost-Effective Maintenance: Coil replacement is possible, extending the lifespan of the contactor.
• Optimal Protection: Recommendations for short-circuit, overload, and overvoltage protection are provided, ensuring the safety of the device and connected equipment.

Standard

The Siemens 3RT2336-1AU00 contactor adheres to the following international standards:

• IEC 60947-1
• IEC 60947-4-1
• IEC 60947-5-1 (auxiliary switches)

Technical Details & Protection

Protection of Device Connections: All connections should be protected against overload and short circuits. Detailed information for protection of free-standing contactors can be found in the technical product data sheet. For device combinations (contactor with overload relay or circuit breaker), refer to the Digital Configuration Manual for load feeders.

Short-circuit and overload protection of auxiliary connections: Refer to the technical product data sheet for information on protecting auxiliary contacts.

Short-circuit and overload protection of control supply voltage: Adhere to relevant standards for control panel configuration and cable dimensioning. Consider power supplies with current-limiting functions and select appropriate protection devices based on load characteristics (inrush current, switch-on/holding power).

Protection against overvoltage at the control supply voltage connection: 3RT23 contactors can be retrofitted with surge suppressors (RC elements, varistors, diodes, or diode assemblies) ordered separately. Note that damping increases break times and opening/closing delay times of contacts.

Application

The Siemens 3RT2336-1AU00 contactor is ideally suited for:

• Four-pole switching of weak or non-inductive loads (AC-1).
• Disconnecting loads or power generation plants from the grid.
• Transfer switching applications.
