핵심 기술 매개변수
연락 시스템

Contact Configuration: 3지 (three sets of changeover contacts), supporting a resistive load of 5A (220VAC/28VDC), suitable for multi-circuit control scenarios.

Material and Service Life: Silver alloy contacts ensure low contact resistance (≤100mΩ), with an 전기 같은 service life of up to 100,000 operations and a mechanical service life of up to 10,000,000 운영.

단열 성능: The withstand voltage between the coil and contacts is 1500VAC, and the withstand voltage between open contacts is 500VAC, meeting industrial-grade safety standards.

Coil Characteristics

Voltage Range: Comprehensive specifications for DC (5-220다섯) and AC (6-380다섯). Power consumption is 0.9W (for DC) or 1.8VA (for AC). The pull-in voltage is ≤75% of the rated voltage (for DC) or ≤80% of the rated voltage (for AC).

Response Speed: The operate time is ≤25ms, and the release time is ≤25ms, making it suitable for high-frequency and rapid switching requirements.

환경 적응성

작동 온도: -25℃ to +55℃, with a humidity of ≤95% (at 25℃). It can work stably in high-dust or vibrating environments (double amplitude: 1.0mm, 빈도: 10-55헤르츠).

Mounting Methods: Supports plug-in, PCB soldering, and DIN rail mounting. Matching socket models include CZY11A-E (dimensions: 72×30×31mm).

Application Fields
산업 자동화

– Used for motor control and the start-stop of production line equipment, capable of switching multiple signal circuits simultaneously.

– Typical Application: Used as an intermediate relay in PLC control systems to achieve logical signal amplification and isolation.

Energy and Power

– Suitable for protection circuits in low-voltage distribution cabinets, capable of monitoring current/voltage abnormalities and triggering circuit breaks.

– Supports high-voltage scenarios of 240VAC (model compatibility needs to be confirmed).

Smart Buildings

– Controls the zoned power supply of lighting and air conditioning systems, and achieves automated energy conservation in combination with sensors.

III. Market Adaptability

Certification Compliance

– Certified by UL, CE, and CQC, complying with North American and EU safety standards, and can be directly used in the U.S. market.

대체 솔루션

– Compatible with similar models such as MY3(N) and HH53P(-엘), with consistent pin definitions and mounting dimensions, facilitating equipment upgrades.

International Procurement

Domestic Price: Approximately 10-20 단위당 인민폐 (including value-added tax). 대량 구매의 경우, orders can be placed via WhatsApp: 0086-13811255435.

U.S. Channels: It is recommended to contact Chint North America via WhatsApp: 0086-13811255435 to obtain authorized distributor information, or purchase through the WhatsApp platform: 0086-13811255435 (stock availability needs to be confirmed).

Notes: If a 120VAC model is required, it must be customized through official channels or used with a step-down module to avoid damage caused by direct connection.

Selection and Installation Recommendations
Model Identification

– Example of a complete model: JZX-22F(D)/3Z AC220V, where “D” indicates with a status indicator light, “3지” represents three sets of contacts, 그리고 “AC220V” is the coil voltage.

배선사양

– Ensure tight contact for plug-in terminals. When soldering to PCB, pay attention to the pin polarity to avoid poor contact caused by cold soldering.

– It is recommended to use the matching CZY11A-E socket, whose screw-type terminals support quick wiring and feature an anti-misinsertion design.

환경 보호

– In humid environments, a sealed type (such as a model with a cover) should be selected. Regularly check the contact oxidation status, and use contact cleaner for maintenance if necessary.
