Features and benefits:

• Early-opening NC contact ensures control circuit disconnection before the main contacts open, improving safety in motor applications.
• Late-closing NO contact provides reliable status signaling only after the main contacts have fully closed.
• Wide compatibility across the entire TeSys VARIO V-series range (V0 through V6) simplifies spare parts management.
• Rated to 690 V AC and 8 kV impulse withstand voltage, suitable for demanding industrial environments.
• Halogen-free materials and recyclable cardboard packaging support sustainability requirements.

Applications:

• Motor control and protection panels requiring auxiliary signaling contacts on VARIO disconnect switches.
• Industrial automation cabinets where early-break / late-make sequencing is required for interlock circuits.
• Machine tool control systems using TeSys VARIO V-series as main motor isolators.
• Process industry panels with PLC feedback loops dependent on contact position signaling.

Compliant with IEC 60947-5. Part of the Schneider Electric TeSys VARIO range.
