Figura 1: The WAGO Electronic Circuit Breaker Model 787-3668, shown with its main unit and three included pluggable connectors. The main unit is a rectangular, off-white device with ventilation slots on top and an array of eight green LED indicators on its front face, corresponding to eight channels. Below the LEDs, the model number "787-3668" is visible. The connectors are black, plastic, and designed for easy wiring, with one larger 8-pin connector and two smaller 2-pin connectors.
The WAGO 787-3668 is an electronic circuit breaker designed to protect 24VDC power supplies and loads from overcurrents and short circuits. It features eight independent channels, each with an adjustable current trip setting. The integrated signal contact provides remote status indication, allowing for proactive system management.
Características principales:
- 8 independently monitored channels.
- Adjustable current trip settings from 1A to 10A per channel.
- 24VDC input voltage compatibilidad.
- Integrated signal contact for status feedback.
- Compact design for DIN rail mounting.
Información de seguridad
Always adhere to local and national electrical codes and regulations. Installation and maintenance should only be performed by qualified personnel. Disconnect power before working on the device or connected circuits. Ensure proper grounding. Do not operate the device if it appears damaged.
Configuración e instalación
Montaje:
The WAGO 787-3668 is designed for DIN rail mounting. Ensure adequate ventilation space around the unit.
Conexiones de cableado:
Refer to the wiring diagram below for correct connections. Use appropriate wire gauges for the expected current loads.
- Input Power (24VDC): Connect the 24VDC power supply to the designated input terminals. Observe polarity.
- Output Channels (1-8): Connect each load to its respective output channel.
- Contacto de señal: Connect the signal contact terminals to your monitoring system for status indication. This is typically a normally open (NO) or normally closed (NC) contact, consult the device labeling for specific configuration.
Nota: The device uses pluggable connectors for easy wiring and maintenance. Ensure all connectors are securely seated after wiring.
Instrucciones de funcionamiento
Configuración actual:
Each channel has an individual rotary switch or similar mechanism for setting the trip current from 1A to 10A. Set each channel's current according to the maximum operating current of the connected load, ensuring a suitable safety margin.
Indicadores de estado:
Each channel is equipped with an LED indicator:
- LED verde: Channel is active and supplying power.
- LED rojo: Channel has tripped due to overcurrent or short circuit.
- Sin LED: Channel is off or no power is supplied to the unit.
Resetting a Tripped Channel:
If a channel trips (red LED), identify and resolve the cause of the overcurrent or short circuit. Once the fault is cleared, the channel can typically be reset by cycling the power to the unit or by a dedicated reset mechanism if available (consult device labeling for specific reset procedure).
Mantenimiento
The WAGO 787-3668 is designed for minimal maintenance. Periodically inspect the unit for:
- Conexiones sueltas.
- Signos de daño físico o sobrecalentamiento.
- Accumulation of dust or debris (clean with a soft, dry cloth if necessary).
Ensure proper ventilation is maintained around the unit to prevent overheating.
Solución de problemas
| Problema | Posible causa | Solución |
|---|---|---|
| Channel LED is Red | Overcurrent or short circuit on the channel. | Identify and clear the fault on the connected load. Reset the channel. |
| No hay LED iluminados | No input power to the unit or unit is off. | Check 24VDC input power supply and connections. Ensure unit is powered on. |
| Channel trips immediately after reset | Persistent fault on the load or incorrect current setting. | Thoroughly inspect the load for short circuits or excessive current draw. Verify the channel's current setting matches or exceeds the load's normal operating current. |
| Signal contact not working | Incorrect wiring or monitoring system issue. | Verify signal contact wiring. Check the configuration of the monitoring system. |
