The ELR-4MD DC Earth Leakage Relay is manufactured by CQ Bluejay, located in Jiangbei District, Chongqing, China. This device incorporates a Hall‑effect current sensor to continuously monitor residual DC current on busbars or branch circuits. When the measured leakage exceeds a preset threshold, the relay issues a clear alarm signal and holds the alarm until a reset command is received. The unit provides two SPDT relay contacts for alarm indication and downstream control.
Typical DC earth‑leakage relays are rated for 24 V DC supply voltage and can handle continuous currents up to 10 A, with a selectable trip threshold commonly between 20 mA and 100 mA. Response times are usually under 10 ms, and isolation voltage to earth may reach 1500 V AC, meeting IEC 61008 standards. The ELR‑4MD is mounted on a standard 35 mm DIN rail and includes RS‑485 Modbus communication for remote monitoring. Adjustable trip levels and time‑delay settings allow integration into diverse protection schemes.
Typical users include data‑center operators, renewable‑energy installations and electric‑vehicle charging stations that require early detection of DC leakage faults. Importers should request the exact trip‑level setting range, test reports for Hall sensor accuracy, and confirm whether the relay includes any certifications such as CE or UL. Packaging is described as standard DIN‑rail ready units, but dimensions and palletisation details need verification before finalising shipping arrangements.

Sourcing ELR-4MD DC Earth Leakage Relay from CQ Bluejay - China Import Guide
Prior to ordering, confirm that the ELR‑4MD meets the required leakage detection sensitivity for your application and that it complies with any relevant safety standards such as IEC 61008. Ask the supplier for a copy of the type test report and, if needed, arrange a third‑party verification of the Hall‑sensor accuracy. Clarify whether the unit carries CE, UL or other certification marks, as this information is not listed.
Logistics terms are not disclosed in the current data, so importers should ask CQ Bluejay to specify the expected lead time, preferred Incoterms (e.g., FOB or CIF) and acceptable payment methods such as T/T against documents. Understanding the pallet size, weight and container loading plan will help avoid unexpected freight charges. Early agreement on these details reduces the risk of delays at the port of loading or discharge.
For quality assurance, organise an inspection that checks the relay’s mechanical mounting, electrical continuity of the SPDT contacts and functional alarm operation. Request the supplier’s test certificates for isolation voltage, trip threshold accuracy and communication protocol compliance. Maintaining these records will simplify customs clearance and provide a basis for any warranty claims.
