• Size: S00 (Compact)

Benefit

1. High Reliability & Durability: Designed for a long mechanical service life, ensuring consistent performance in demanding industrial environments.
2. Integrated Surge Protection: The plugged-on varistor protects the coil and control circuit from damaging voltage surges, extending the product lifespan.
3. Space-Saving Design: The compact Size S00 form factor allows for efficient use of space within control cabinets.
4. Simplified Wiring: Features user-friendly screw terminals for quick, secure installation and maintenance.
5. Enhanced Control: The captive $2\text{NO}+2\text{NC}$ auxiliary contacts provide essential feedback and control interfaces for complex automation systems.

Functin

The 3RT2016-1CP04-3MA0 functions as an electromechanical switching device. When the $230\text{V AC}$ coil is energized, the main contacts close, allowing power to flow to the connected load, typically a motor. It is primarily used for:

• Switching Motors: Starting and stopping three-phase AC motors.
• Resistive Loads: Switching non-inductive or lightly inductive loads.
• Interface to Automation: The auxiliary contacts provide signaling for interlocks, status indication, and other control functions within the automation level.
