2. Informació de seguretat
- Risc elèctric: Installation and maintenance must be performed by qualified personnel only. Ensure power is disconnected before any work on the contactor or associated circuits.
- Voltage: Comproveu que el volum de subministramenttage matches the contactor's rated voltage (220VAC for this model).
- Protecció contra sobreintensitat: Install appropriate overcurrent protection devices (e.g., circuit breakers) upstream of the contactor.
- Cablejat: Use correct wire gauges and ensure all connections are tight to prevent overheating and electrical arcing.
- Medi ambient: Do not install in environments with excessive moisture, dust, corrosive gases, or extreme temperatures outside the specified operating range.
3. Característiques del producte
The GEYA GYHC-25 Modular Contactor incorporates several design elements for enhanced performance and user convenience:
- Baix consum d'energia: Optimized electromagnetic system significantly reduces holding power, addressing high energy consumption common in traditional contactors.
- Funcionament de baix soroll: Advanced design and automated manufacturing processes minimize operational noise.
- Vida útil ampliada: Offers an electrical life exceeding 100,000 cycles and a mechanical life greater than 12,000,000 cycles.
- Materials de qualitat: Constructed with custom plastic, brand silver points, and RoHS compliant components.
- Finestra de visualització: An integrated instruction window clearly indicates the contactor's on/off state.
- Transparent Flip Cover: A new transparent flip cover design allows for easy identification and labeling.

4. Configuració i instal·lació
The GEYA GYHC-25 contactor is designed for Din Rail mounting. Follow these general steps for installation:
- Desconnexió d'alimentació: Ensure all power to the circuit is completely disconnected at the main breaker before beginning installation.
- Muntatge: Securely attach the contactor to a standard 35mm Din Rail. Ensure it clicks firmly into place.
- Cablejat: Connect the control circuit to terminals A1 and A2. Connect the main power circuit to terminals 1 and 2. For this 1NC model, terminal 1 and 2 will be normally closed, meaning current flows when the coil is de-energized, and opens when the coil is energized. Refer to the wiring diagram below for proper connections.
- Verificació: Double-check all wiring connections for tightness and correctness.
- Restauració d'energia: Un cop finalitzada i verificada la instal·lació, restableix l'alimentació del circuit.

5. Instruccions de funcionament
The GEYA GYHC-25 is an automatic modular contactor. Its operation is controlled by the voltage applied to its coil terminals (A1 and A2).
- Energitzant la bobina: When the rated control voltage (220VAC for this model) is applied to terminals A1 and A2, the contactor coil energizes.
- Contact State Change: For the 1NC (Normally Closed) model, energizing the coil will cause the main contact (between terminals 1 and 2) to open, interrupting the circuit. When the coil is de-energized, the contact will return to its closed state, completing the circuit.
- Indicació d'estat: Observe the visualization window on the front of the contactor. This window will indicate the current on/off state of the contacts, providing a clear visual confirmation of operation.
6. Manteniment
Regular maintenance ensures the longevity and reliable operation of your contactor.
- Inspecció periòdica: Annually inspect the contactor for any signs of physical damage, discoloration, or loose connections.
- Neteja: Ensure the contactor is free from dust and debris. Use a dry, soft cloth for cleaning. Do not use solvents or abrasive cleaners.
- Estanquitat del terminal: Periodically check the tightness of all terminal screws. Loose connections can lead to overheating and failure.
- Condicions ambientals: Ensure the operating environment remains within specified conditions (temperature, humidity, absence of corrosive substances).
7. Solució De Problemes
If you encounter issues with your GEYA GYHC-25 contactor, consider the following:
- Contactor Not Operating:
- Comproveu si el volum de controltage (220VAC) is correctly applied to terminals A1 and A2.
- Verify that the control circuit wiring is correct and secure.
- Ensure there is no power interruption to the control circuit.
- Sobreescalfament:
- Comproveu si hi ha connexions de terminals soltes.
- Ensure the load current does not exceed the rated current (25A for AC-7a, 9A for AC-7b).
- Verifiqueu la ventilació adequada al voltant del contactor.
- Soroll inusual:
- Ensure the mounting is secure and the contactor is not vibrating against other components.
- If the noise persists and is significant, the unit may require replacement.
For issues not resolved by these steps, contact qualified electrical personnel or GEYA customer support.
