The contactor for R. STAHL's 8550 series is a motor load contactor for use in motor starters up to 37 kW / 50 hp at 400 or 480 V and other performance-oriented applications. It switches AC-3, -4, -5 and -6 loads just as reliably as AC-1 operating currents. Values are also available for DC-1, -3 and -5. With just three coil voltage ranges, control voltages of 20 to 280 V are covered. Up to four auxiliary contacts are optionally available. Supplemented by the moulded case circuit breaker and overload relay also available in this series, motor starters up to 37 kW / 50 hp at 400 to 480 V are available (other powers available on request).
- Safe control of motors and other loads in motor starters and power distribution boards
- Reliable protection of motors in connection with the overload relay
- Can be used globally thanks to international approvals
- Extensive flexibility thanks to wide-range coil voltages
- Large clamping range for main terminals
