• Interlocked opposing contacts prevent simultaneous N/O and N/C activation for safe signaling
• Retrofits directly onto the right side of PKZ0 motor-protective circuit-breakers without rewiring
• Fewer than 1 failure per 100,000,000 operations at 24 V DC for high-reliability control circuits
• Safe isolation at 440 V between auxiliary and main contacts per EN 61140
• Operating range of -25 °C to +55 °C suits demanding industrial panel environments

Applications:

• Run/stop status signaling in motor starter control panels
• Direct-on-line and reversing starter assemblies built around PKZ0 motor-protective circuit-breakers
• PLC or relay logic inputs requiring volt-free contact feedback from motor starters
• Industrial switchgear assemblies requiring IEC/EN 60947-4-1 compliant auxiliary contacts
• Panel builder installations where overvoltage category III pollution degree 3 ratings are required

Compliant with IEC/EN 60947-4-1, UL 508, and CSA-C22.2 No. 14. Part of the Eaton Moeller series NHI accessory range for motor-protective circuit-breakers.
