Application

The 3RT2517-2FW48-0PT4 serves as an electrically controlled switch (contactor) to safely and remotely control power to electrical loads. It is primarily used for:

1. Switching 4-wire power distribution systems (e.g., L1, L2, L3, N or two separate circuits).

2. Controlling lighting, heating elements, and other resistive or inductive loads.

3. Acting as an intermediate relay for high currents in automated machinery and process control systems.

4. Integration into motor starters, combining with a SIRIUS overload relay.
