Import Current Monitoring Relay Dzb-1 — Buy in wholesale FOB from Supplier in China

The Current Monitoring Relay DZB-1 from Cixi Feinade Electrical Appliance Plant is a three-phase device designed for comprehensive electrical protection, including short-circuit, locked-rotor, overcurrent, undervoltage, and phase unbalance detection. It supports a wide current range of 1-10A to 800A across multiple models, with rated voltages of 220VAC and 380VAC at 50/60Hz. The unit features a built-in LED display and keypad for precise digital settings, alongside optional RS-485 communication and 4-20mA analog output for integration into larger monitoring systems.

Constructed with an integrative design, the DZB-1 measures 118 mm x 54 mm x 135 mm and is mounted via screw fixing, a standard method for industrial relays. It includes two changeover (C/O) output contacts, one for trip and one for alert, with a contact capacity of 3A at 380VAC. The relay can also couple with a zero-current transformer (ZCT) for earth fault detection, a critical feature in many industrial applications. Typical materials for the enclosure include flame-retardant polycarbonate, which is standard for such protective devices.

This relay is commonly used in pumps, fans, blowers, motors, and compressors, where reliable protection against electrical faults is essential. It carries CE and RoHS approvals, which are standard certifications for electrical components sold in international markets. Buyers should confirm the exact current range, voltage rating, and optional features required for their application, as these vary across the DZB-1 series. The supplier, based in Ningbo’s Hangzhou Bay New Zone, specializes in electrical appliances and offers this relay as part of its industrial control product line.

Cixi Feinade Electrical Appliance Plant is located in the Hangzhou Bay New Zone of Ningbo, Zhejiang Province, China, with a postal code of 315300. The company specializes in the manufacture of electrical appliances, including industrial control and protection devices such as the DZB-1 current monitoring relay. Its focus on electrical components suggests a targeted expertise in this niche, though no additional details about production capacity or client base are provided in the available data.

The supplier’s trust tier is classified as harbor, and like the previous listing, it has not established a response rate or average response time. This indicates limited interaction history, so buyers should proactively reach out to confirm details such as lead times, certifications, and technical support. The company’s address in Ningbo places it in a region known for electrical and industrial manufacturing, which may offer logistical advantages for sourcing.
