Key Features

1. High-Current Switching Capacity
   • Handles up to 192 A (AC-1) and 160 A (AC-3) for heavy industrial loads.
   • Supports 150 HP motor control at 460 V three-phase, ideal for large machinery.
   • Durable silver-alloy contacts resist wear and welding under high inrush currents.
2. Dual AC/DC Coil Compatibility
   • Universal 110–127 V AC/DC coil operates on both alternating and direct current.
   • Wide voltage tolerance ensures stable operation despite minor power fluctuations.
   • Low coil power consumption reduces energy costs and heat generation.
3. Robust Industrial Construction
   • Reinforced thermoplastic housing provides insulation and protection against dust and moisture.
   • Vibration-resistant design withstands mechanical stress in industrial environments.
   • Finger-safe terminal covers prevent accidental contact during maintenance.
4. Flexible Configuration & Integration
   • 1 NO + 1 NC auxiliary contacts enable versatile control and status monitoring.
   • Bus bar terminals support high-current wiring and simplify panel assembly.
   • Snap-on accessories (auxiliary blocks, surge suppressors) enhance application flexibility.
5. Global Compliance & Reliability
   • Certified to UL, CSA, IEC, and CE standards for international use.
   • Dual U.S./European markings simplify regulatory compliance across regions.
   • Rigorous factory testing ensures consistent performance and long service life.
