Contact Configuration: 1NO + 1NC
Mounting Type: Side Mount (Left side of starter)
Compatibility: Designed for NS2-25 and NS2-32 series motor starters (often referred to generically as NS2-AU11 in datasheets)
Easy Snap-On Installation
Provides Electrically Isolated Contacts
Remote Status Indication: Allows external circuits (e.g., indicator lights, PLC inputs) to monitor whether the motor starter is ON or OFF.
Control Circuit Interlocking: Enables safety or sequence logic by preventing or allowing other operations based on the starter's state.
Enhanced Automation: Facilitates integration of the manual starter into more complex control systems.
Clear Contact State: Provides both NO and NC contacts for versatile signaling options.

Standards: Conforms to auxiliary contact requirements within IEC/EN 60947 standards.
Control panels requiring feedback on motor starter status.
Applications needing interlocking between the motor starter and other devices.
Adding signaling capabilities (e.g., run/stop lights) to a manual motor starter installation.
Integrating NS2-25 starters with PLC or relay logic systems.
Installation: Ensure the main starter is de-energized before installation. Align the auxiliary contact block with the side mounting slots on the NS2-25 starter and push firmly until it clicks into place (refer to assembly diagrams like Figure 5 or Figure 10 in starter manuals).
Wiring: Connect control circuit wires to the appropriate terminals (e.g., 43-44 for NO, 31-32 for NC). Use appropriate wire size and ensure terminals are tightened securely.
Compatibility: Verify this accessory (AU11 type) is suitable for your specific NS2 starter model (primarily NS2-25, NS2-25X, NS2-32, NS2-32X, NS2-32H). While labeled AUX-NS2-25-AU11, the core component is often the generic NS2-AU11.
Testing: After installation, manually operate the starter (if safe to do so without load) and verify the auxiliary contacts change state correctly using a continuity tester.
