Import Dx Mini Circuit Breaker Mcb — Buy in Bulk from Supplier in China

The Dx mini circuit breaker (MCB) from Yueqing Kangling Electric Appliance Factory is a thermal-magnetic trip device designed for overcurrent and short-circuit protection in low-voltage distribution boards. It operates at 230/400 V AC and supports current ratings from 1 A to 63 A. The unit features a bimetallic strip for thermal overload response and an electromagnet for instantaneous magnetic tripping, conforming to IEC 60898-1 standards for household and similar installations.

The housing is constructed from flame-retardant thermoplastic (UL 94 V-0 rated), and the internal contacts are silver alloy with arc chutes to extinguish electrical arcs during interruption. The operating mechanism is spring-loaded for consistent tripping speed regardless of manual handle position. Typical pole configurations include 1P, 2P, 3P, and 4P, with a standard width of 18 mm per pole. These are common in residential and light commercial panels where space is constrained.

Buyers include electrical contractors, panel builders, and distributors in regions with high demand for cost-effective protection devices. Applications range from home electrical panels to small industrial control cabinets. Packaging is usually in blister packs of 10 or 20 units, with cartons of 100 to 500 pieces. Trade terms are typically FOB Ningbo or CIF, with lead times of 15 to 25 days. MOQ is not stated and must be confirmed directly with the supplier.
