Application

The 3RT2535-1AB00 contactor primarily functions as a remotely controlled switch in electrical circuits. Its 4-pole (2 NO + 2 NC) main contacts make it ideal for:

1. Motor Control: Switching 3-phase AC motors (AC-3 category) or controlling loads where four distinct poles are required.

2. Load Switching: Handling high-current resistive and non-inductive loads (AC-1).

3. Circuit Isolation: Providing a safe disconnection point in industrial machinery.

The combination of main and integrated 1 NO + 1 NC auxiliary contacts provides immediate feedback on the contactor’s switching status for interlocking and control circuitry.
