FAQ:

What is the advantage of the black nickel plating on the ST Series shell compared to ordinary plating?

The black nickel plating on the ST Series shell has better corrosion resistance and wear resistance than ordinary zinc plating or chrome plating. It can form a dense protective film on the surface of the zinc alloy, effectively resisting the erosion of moisture, dust and mild corrosive media, and is more suitable for harsh working environments that require corrosion resistance.

What does V-0 flame resistance mean for the WT29 series?

V-0 means the shell self-extinguishes within 10 seconds when ignited (no burning droplets), meeting strict fire safety standards for industrial environments.

Can the WT29 series be used with cables larger than 2.5mm²?

No. The max wire size is 2.5mm²/16AWG. Using larger cables may cause poor connection or terminal damage.

What's the difference between plastic and metal housings of Weipu heavy-duty series?

Plastic housing: Lightweight, corrosion-resistant, cost-effective, suitable for mild low-vibration scenarios; Metal housing: High mechanical strength, strong vibration resistance, suitable for high-load high-vibration industrial equipment.
