Reliable threepole switching suitable for mediumload applications, simplifying circuit design in control panels. Standard 220V AC coil designed for common 50/60 Hz power systems, allowing straightforward integration into existing control circuits. Compact and straightforward installation for industrial environments, reducing panel space and wiring complexity. Clear model identification (JZC422) with explicit coil voltage and contact arrangement, supporting easy replacement and compatibility checks. Key attributes Model: JZC422 Type: Intermediate relay / AC contactor Coil voltage: 220V AC Coil frequency: 50/60 Hz Poles: 3 Main contacts: rated for 16A Auxiliary contacts: 2 normally open (NO) and 2 normally closed (NC) Appearance/finish: Color: Jzc422 (as specified), Size: 220V (coil) Package: 1 piece Compatibility and performance Suitable for switching threepole loads in 220V AC control circuits Compatible with standard 50/60 Hz electrical systems Provides dual auxiliary contact sets for interlocking, feedback, and sequencing in automation circuits Designed for use in control panels and equipment requiring reliable remote switching of mediumpower loads Typical use cases Threephase motor control: Use the three main contacts to switch a motor up to its 16A rating, with the 2 NO/2 NC auxiliary contacts used for overload interlock and feedback signaling to a control circuit. HVAC or environmental control: Control fans, dampers, or heaters in ventilation and climate systems, utilizing the NO/NC auxiliary contacts to implement safety interlocks or status indications. Industrial automation interlock: Implement sequencing and safety interlocks in machines or conveyors, where auxiliary contacts provide feedback to PLCs or control relays without additional devices. How to use Connect the controlled load to the three main contacts; ensure the load does not exceed the 16A rating. Wire the control circuit to the 2NO and 2NC auxiliary contacts to achieve desired interlock and status signals. Supply the coil with 220V AC at 50/60 Hz to energize the relay and switch the main load accordingly. Notes Verify coil voltage and frequency match the control supply (220V AC, 50/60 Hz). Confirm wiring configuration aligns with the intended NO/NC logic for reliable operation. This description reflects the model's specified features: JZC422, 220V coil, 50/60 Hz, threepole main contacts with 2 NO and 2 NC auxiliary contacts, rated main current 16A, single unit package.
