About SENTOP Electrical Co., Ltd.

Quem somos
One electrical supplier for focused products and connected requirements.
Based in Leqing City, Wenzhou, Zhejiang Province, China, SENTOP serves distributors, wholesalers, panel builders, system integrators, equipment manufacturers, OEM buyers and project procurement teams.
Our strongest product focus is terminal blocks, transfer switches and digital panel meters. At the same time, many customers need circuit breakers, protection devices, contactors, power supplies, distribution boxes and other low-voltage products in the same purchasing program. SENTOP organizes these requirements by priority without separating products that must work together in the customer’s system.

Customer problems we help organize
Start with the purchasing problem, not a guessed model number.
Send the information you already have. SENTOP can use it to identify the product details that still need confirmation.
I need to replace an existing product.
I need a complete terminal strip.
I need a transfer switch or panel meter.
I need several low-voltage product lines.
I need OEM or repeat-order consistency.
Customers we support
Electrical products must fit both the system and the purchasing plan.
SENTOP works with B2B customers who need application understanding, model identity, documents and supply continuity beyond a one-time price comparison.
Factory, inspection and delivery
Trust depends on how the approved requirement reaches the shipment.
Customers need more than a general factory promise. The exact product, inspection focus, labels, accessories, packaging and shipment identity must stay connected to the order.
