Function

The Siemens 3RT2016-2SB42 power contactor functions as an electrically operated switch. When the 24V DC control voltage is applied to its coil, it closes the main power contacts, allowing current to flow to the connected load (e.g., an electric motor). The single NC auxiliary contact simultaneously opens, which can be used for interlocking or signaling purposes in a control circuit.

The built-in suppressor diode dissipates the energy from the coil when the control voltage is removed, preventing damage to sensitive electronic components in the control system. The spring-loaded terminals provide a gas-tight and permanent connection, crucial for reliable performance in harsh industrial conditions.
