The WEIDMÜLLER PV Next firefighter switch It is a critical safety solution for roof photovoltaic installations, designed for remote chain disconnection at the entrance point to the building. This device allows emergency services to work without electrical risks, interrupting the DC connection between the panels and the inverter immediately after a cut of AC power over five seconds. Your advanced engineering includes a automatic readjustment that restores the connection when the power supply returns, eliminating the need to reset manual. Built in a robust box Polyester reinforced with fiberglass with certification Ip65, it is ideal for protected outdoors. Supports a nominal tension of 1100 V DC and has connection technology Push in For drivers up to 16 mm², guaranteeing a quick, safe installation and reliable performance under demanding conditions.

 

Maximum safety and performance for your photovoltaic installation

The Weidmüller PV Next Fireman Switch it acts as an intelligent remote circuit breaker that prioritizes security without compromising system efficiency. Its main virtue is the automatic readjustment: After an emergency interruption or network failure, the switch reconnects the photovoltaic chains autonomously once the AC voltage is restored by more than five seconds. This minimizes production losses by avoiding technical displacements to rear the equipment.

In addition, the device integrates a thermal safety protection: If the internal temperature of the box exceeds 100 ° C, the switch automatically switches to the OFF position to protect internal components and prevent greater risks. . Its reinforced polyester envelope offers exceptional resistance to impacts (IK10) and superior durability against external agents.

FAQ - Frequently Asked Questions

  1. What happens if the power supply of the building is cut? The equipment automatically changes to the off position (OFF), interrupting the DC connection between the solar pictures and the inverter after the AC power is interrupted for more than five seconds.
  2. Is it necessary to climb the roof to rear the equipment after a shutdown? No. Thanks to its automatic recieve function, the switch restores the DC connection autonomously once the AC power is restored for more than five seconds.
  3. How do I know if the switch has worked correctly? The device includes a signaling Assistant Contact (24 V DC) that allows remote monitoring the switch status from an external control system.
  4. What happens if the equipment is heated too much? If the internal temperature exceeds 100 ° C, the switch automatically turns off to protect its internal components. Once the status is verified, it can be rearunk by restarting the alternating current.
  5. What security regulations do this equipment meet? It is approved under international standards for low voltage rack IEC 61439-1 and EN 61439-2, complying with the required standards for emergency services.
