ELPR

Product catalog summary

Overview: The Sifam Tinsley Earth Leakage Relay (ELPR) is a protection device designed to prevent electric shock and equipment damage due to insulation failures or contact with live parts. It monitors earth leakage current and disconnects the circuit if hazardous levels are detected. The ELPR is available in two versions: Smart and Smart+.

Applications: The ELPR is suitable for motor protection, mining equipment, industrial premises, and substations.

Product Features:

Easy operation with front access potentiometer for setting leakage current and trip time.
CBCT connection fault detection with LED indication.
True RMS measurement up to the 15th harmonic.
Programmable parameters for leakage current (30mA to 30A) and trip delay (0s to 10s).
Test and reset keys for manual operation.
Remote reset capability.
LED indications for power, fault, and alarm states.
Relay output with configurable settings via DIP switch (Smart+ version).

Technical Specifications:

Input characteristics: Leakage current range from 30mA to 30A.
Auxiliary supply options: 60-300V AC/DC or 20-60V DC/20-40V AC.
Accuracy: Leakage current accuracy of ±5% of full scale.
Environmental conditions: Operating temperature from -20°C to +65°C, storage temperature from -40°C to +70°C, and relative humidity up to 90% non-condensing.
Compliance with standards: IEC 61326, IEC 60947-2, IEC 60755, and IEC 61010-1.

Ordering Information: The product code includes options for auxiliary supply, model type (Smart or Smart+), and additional outputs. The Smart+ model offers DIP switch configurations for auto-reclosure, relay configuration, and main relay state.
