Complete Building Electrical System Solutions — One Brand, Full Coverage
TOSUNLUX delivers a full range of low voltage distribution products for building projects — from main switchgear to final circuits. Simplify your inventory, strengthen your market, and serve your customers with one trusted, certified brand.
Why Sourcing Building Electrical Components from Multiple Suppliers Fails
Distributors worldwide face the same costly frustrations when piecing together low voltage electrical products from different factories.
Inconsistent Electrical Product Quality Across Suppliers
Sourcing MCBs from one factory, distribution boards from another, and accessories from a third creates mismatched specs and unpredictable quality — leading to returns, complaints, and lost customer trust.
Incomplete Product Range Means Lost Project Orders
When a contractor needs a full building electrical kit and your catalog has gaps, the entire order goes to a competitor who can supply everything under one roof.
Unbranded Products Are Harder to Sell Without Certifications
Without internationally recognized certifications and a credible brand behind the products, your sales team struggles to win trust from engineers, contractors, and project specifiers.
