Overview: Compact and Reliable Motor Switching
The Siemens 3RT2024-1AP60 is a highly efficient and compact 3-pole power contactor from the SIRIUS 3RT2 series, designed for reliably switching motors up to 5.5 kW (at 400 V) or 12 A (AC-3/AC-3e rated current). As a core component in industrial control panels, this IEC contactor is engineered for high performance, prolonged mechanical service life, and ease of integration.
It features a durable design, a compact Size S0 frame, and user-friendly screw terminals for secure wiring. This specific model includes a universal control coil voltage of 220 V AC (50 Hz) / 240 V AC (60 Hz) and integrated auxiliary contacts (1 NO + 1 NC) for control circuit feedback. It is the modern, direct replacement for the obsolete 3RT1024-1AP60.
Benefits & Advantages
- Space-Saving Design: Compact Size S0 for efficient use of panel space in control cabinets.
- High Reliability: Tested for a long mechanical service life of up to 10 million switching cycles, ensuring maximum uptime.
- Global Standard Compliance: Conforms to international standards, including IEC 60947.
- Easy Integration: Part of the modular Siemens SIRIUS industrial controls system, allowing seamless pairing with accessories like 3RU2 thermal overload relays or 3RB3 electronic overload relays.
- Dual Frequency Coil: Operates reliably on both 50 Hz and 60 Hz networks, offering flexible worldwide use.
Function & Application
The 3RT2024-1AP60 contactor is primarily used for:
- Motor Switching: Safely starting and stopping 3-phase AC motors (Direct-On-Line/DOL starting) up to its rated power.
- Resistive Load Switching (AC-1): Switching resistive loads up to 40 A (at 40 °C).
- General Load Switching: Control of lighting, heating elements, and other industrial loads.
Ideal for applications in: Machine Tools, HVAC systems, Pumping Stations, Conveyor Systems, and other industrial automation environments requiring dependable motor control.
