Import Circuit Breaker Mccb Mcb — Buy in Bulk from Supplier in China

The Circuit Breaker MCCB MCB from Tengen Group Co., Ltd. is a thermal-magnetic circuit protection device designed for industrial and commercial electrical systems. It features adjustable trip settings with a current rating range from 10A to 630A, supporting single-pole to four-pole configurations. The device complies with IEC 60947-2 standards for low-voltage circuit breakers and is constructed with flame-retardant thermoplastic housing and silver alloy contacts for durable arc interruption.

Typical variants include models with manual or handle-operated operation, and options for overcurrent and short-circuit protection via independent thermal and magnetic tripping elements. The thermal element responds to sustained overloads with a time-delay characteristic, while the magnetic element triggers instantly during high-current faults. These devices are commonly used in distribution boards where precise coordination between upstream and downstream protection is required. Standard insulation voltage is 690V AC, and the mechanical endurance exceeds 10,000 operations.

This circuit breaker is purchased by electrical contractors, panel builders, and facility managers in manufacturing, data centers, and commercial construction. Buyers typically source units in bulk for integration into switchgear assemblies. Packaging is in cartons of 10 to 50 units, depending on frame size. Trade terms are commonly FOB from Ningbo or Shanghai port, with lead times of 25 to 40 days after order confirmation. MOQ varies by model and is confirmed directly with the supplier.

Tengen Group Co., Ltd. operates from a manufacturing facility in Liushi, Wenzhou, Zhejiang Province, a known hub for low-voltage electrical components in China. The supplier is listed as imported with harbor-tier trust verification, indicating active participation in international trade channels. The listing does not disclose production capacity, employee count, or years in operation. Response metrics show no recorded activity, suggesting the supplier may operate through a trading agent or lacks direct buyer communication infrastructure.

The company appears focused on producing and exporting circuit breakers and related electrical devices, with no claims of certifications, awards, or client lists in the source data. There is no evidence of in-house R&D, testing labs, or ISO certification. Buyers should treat this as a manufacturer-level exporter without verified quality management systems unless independently confirmed. Packaging and shipping logistics are handled through third-party forwarders in Zhejiang ports.
