Specifications
Product Description
The MC4 Solar Connector 3 to 1 WSPVY3 40A 1000V DC is a “Y” type branch connector that groups three photovoltaic strings into a single MC4 output, optimizing cabling and reducing installation time. Manufactured with high-strength materials and environmental protection rating IP65, it offers electrical safety, low voltage drop, and a stable connection even in demanding environments.
Main Features
- Rated current 40 A for high string currents without overheating.
- Rated voltage 1000 V DC and test voltage 6000 V (50 Hz, 1 min) for maximum dielectric robustness.
- Contact material: tinned copper with contact resistance ≤ 1 mΩ, minimizing losses.
- Housing in UV-resistant PPO/PC, flame class UL94-V0 and double insulation (Class II).
- Protection rating IP2X/IP65: touch safety and protection against dust/water jets.
- Insertion force ≤ 50 N and extraction force ≥ 50 N; secure connection with multiple coupling cycles.
Advantages or Benefits
- Reduces the number of cables reaching the combiner box or inverter, simplifying installation.
- Improves system reliability with tinned copper contacts and low resistance.
- IP65 protection and self-extinguishing materials for safe outdoor operation.
- Design with keyed housings prevents polarity errors and incorrect connections.
- Wide thermal range (-40 °C to +110 °C) for extreme climates without premature degradation.
Purpose or Applications
Ideal for residential, commercial, or industrial photovoltaic installations where it is necessary to combine three identical solar strings into a single input, whether to a DC combiner, protections, or to an MPPT that accepts the sum of currents.
