Import Ebs9b Series Overload Protection Device — Buy in Bulk from Supplier in China

The EBS9B series overload protection device is a thermal-magnetic circuit protector designed for industrial motor control circuits, with rated currents of 6A, 10A, 16A, 20A, and 25A. It offers two breaking capacity options: 6kA and 10kA, suitable for use in standard 415V AC three-phase systems. The device operates without external power and responds to sustained overcurrent conditions by tripping the contact mechanism, preventing thermal damage to connected equipment.

The housing is constructed from high-temperature resistant thermoplastic, rated to UL 94 V-0 for flame retardancy. Internal components use silver alloy contacts with low contact resistance, and the bimetallic strip is calibrated to industry-standard thermal curves per IEC 60947-4-1. These are typical specifications for industrial-grade overload relays; no internal adjustments are user-accessible, and reset is manual after cooling. The device is not rated for DC applications or high-frequency switching environments.

This device is commonly purchased by manufacturers of CNC machinery, conveyor systems, and HVAC control panels in Southeast Asia and Eastern Europe. Buyers typically order in batches of 50 to 500 units, with packaging in blister cards or bulk trays. Trade terms are negotiable, but standard delivery is FOB Shanghai. Buyers should confirm the exact trip class (Class 10 or Class 20) and ambient temperature rating before ordering, as these affect performance in high-heat environments.

Shanghai Ebasee Electric Co., Ltd. is a manufacturer based in Pudong District, Shanghai, with a registered address at No.2588, Jinhai Road. The supplier is listed as imported and verified through harbor-level checks, indicating direct export capability. The listing does not disclose company history, workforce size, or annual production volume. There is no public record of certifications such as ISO or CE attached to this specific product line in the source data.

The supplier's profile shows no response rate or average response time, suggesting limited buyer communication activity.
