The NC25NC Contactor is a 3-pole + auxiliary contact magnetic switch designed for Industrial Tumble Dryer control systems. This contactor features three main poles (L1, L2, L3) that are Normally Open (NO) for switching power circuits, plus a separate auxiliary contact that is Normally Closed (NC) for control and status feedback. Operating on 220V AC coil voltage with low power consumption of 2.2W, it provides reliable switching for high-current circuits while offering auxiliary signaling capability. With screw/lug connections and durable plastic housing measuring 74x44mm, it is commonly used for controlling heaters, motors, and other high-power components in laundry drying equipment.
• 3 Main Poles (L1, L2, L3): Three independent power switching contacts
• Main Contacts Configuration: Normally Open (NO) -- close when coil energized
• Auxiliary Contact: Separate Normally Closed (NC) contact for control/feedback
• 25A Current Rating: Handles high-current dryer circuits on main poles
• 220V AC Coil: Direct mains voltage operation
• Low Power Consumption: 2.2W coil operation energy efficient
• Screw/Lug Terminals: Secure electrical connections for all contacts
• Compact Size: 74x44mm fits standard control panels
• Industrial Durability: Built for continuous commercial operation
• Heater bank switching in industrial tumble dryers (using L1, L2, L3 NO contacts)
• Motor control in drying equipment (3-phase or single-phase with multiple poles)
• Power switching for high-current dryer circuits
• Control system component with auxiliary feedback (using NC auxiliary)
• Replacement for worn or faulty contactors requiring NO main + NC auxiliary
