$255.51
Siemens 3RT2037-1SF30 power contactor, AC-3e/AC-3, 65 A, 30 kW / 400 V, 3-pole, 83-150 V AC/DC, 50/60 Hz, with integrated varistor, auxiliary contacts: 1 NC, screw terminal, size: S2, F-PLC-IN
Overview
The Siemens 3RT2037-1SF30 is a high-performance, 3-pole SIRIUS power contactor from the globally recognized 3RT2 series, designed for reliably switching motors and other resistive loads. Rated for up to 65 A (AC-3e/AC-3) and 30 kW at 400 V, this Size S2 contactor is ideal for demanding industrial automation applications.
It features a wide-range, low-power consumption 83-150 V AC/DC control coil with an integrated varistor for surge suppression, ensuring maximum control reliability and system longevity. Crucially, the contactor includes the F-PLC-IN (Fail-Safe PLC Input) specification, making it perfect for safe integration into modern safety-oriented control systems. Connection is simplified via robust screw terminals.
Benefit
- Reliable Motor Switching: Rated for up to 65 A and 30 kW, offering high operational reliability for standard and heavy-duty motor applications.
- Enhanced Coil Protection: The integrated varistor minimizes voltage spikes during coil de-energization, protecting the control circuit and extending the coil’s service life.
- Flexible Control: The wide-range 83-150 V AC/DC coil allows for versatile use across different control system voltages without needing separate AC or DC versions.
- Safety Integration Ready: F-PLC-IN capability ensures seamless and safe interfacing with safety-related PLCs and controllers, meeting modern machine safety standards.
- Space-Saving Design: Part of the compact SIRIUS 3RT2 line, the Size S2 model saves valuable panel space.
- Simple Wiring: Proven screw terminal connection system provides secure and straightforward wiring.
Application
The Siemens 3RT2037-1SF30 power contactor is an essential component for controlling various loads in industrial environments, including:
- Starting and stopping standard and high-efficiency (IE3/IE4) three-phase motors.
- Controlling large heating systems and lighting circuits (AC-1 loads).
- Integration into complex automated machinery and plant control systems where safety functions (F-PLC-IN) are required.
