6. Easy Expansion: Compatible with a wide range of SIRIUS 3RT2 auxiliary switch blocks, overload relays (3RU21 thermal or 3RB30 solid-state), and function modules for easy system expansion and motor protection.
7. Robust Terminals: Secure and reliable screw terminals for main and auxiliary circuits ensure long-term, stable electrical connections.

Function

The Siemens 3RT2036-1AP60 serves as a power contactor designed to magnetically switch high-current three-phase electrical loads, primarily induction motors.

• Motor Switching: Safely connects and disconnects the main power circuit to a motor up to $22\text{ kW}$ (at $400\text{ V}$) or $51\text{ A}$ (AC-3/AC-3e rated current) under normal operating conditions.
• Control Integration: The coil is energized by a $220\text{ V}/240\text{ V AC}$ control voltage, which closes the three main poles (3 NO contacts).
• Signaling/Interlocking: The integrated $1\text{ NO}+1\text{ NC}$ auxiliary contacts provide status feedback and are used for interlocking and signaling within the control circuit.
