Firefighter Switch Weidmüller PV Next 1100V 4MPP SPD EVO 2 Plug & Play

Maximum capacity: 4 MPP followers in a single device

The Weidmüller PV Next Fireman Switch 4MPP (reference 8000110665) Represents the range top in fire protection For solar energy. It is designed specifically for installations where inverters of multiple MPP followers are used, Allowing to protect up to 4 independent circuits with a single team. This drastically simplifies the wiring and reduces the installation costs when centralizing the operational security and the Ray protection (SPD type I / II).

The system acts as a remote circuit breaker smart: if the AC of the building by an emergency, the switch instantly cuts the flow of Duty current (DC) From the roof. Once the electrical network stabilizes, Its technology automatic recirement Reconnect the solar panel chains without the need for technicians displacement. His envelope Polyester reinforced with fiberglass guarantees extreme durability against corrosion and UV, Being much higher than standard plastic tables.

Frequently Asked Questions (FAQ)

1. Why choose the 4 MPP model instead of several smaller ones? Choose the model 4mpp centralizes all protections at a single point, reducing the necessary space on wall, simplifying maintenance and ensuring that the 4 followers of the inverter be protected under the same standard photovoltaic security.
2. What happens if my inverter Do you only have 3 MPP? You can use this model perfectly by leaving the fourth follower without connecting (using the WEIDMÜLLER blind plugs). This gives you the maximum SPD protection and future expansion capacity.
3. Is it compatible with the emergency stop button? Yes, this switch can be wired together with the Weidmüller emergency stop button To allow a manual disconnection from the ground level, in addition to the AC Cut Automatic.
4. What advantage does the MC4-EVO 2 connector have in a 4 MPP box? By managing as many current lines, the Low contact resistance of the connectors EVO 2 it is critical to avoid overheating and maximize energy efficiency of the entire installation.
5. Do you comply with fire regulations? Absolutely. Complies with international remote disconnection standards, providing a safe environment for emergency equipment by eliminating the risk of electrocution by duty In the building.
