Four-function current relay, contacts: 2x2P, Imax=16A, DIN rail mounting, 3 modules, EPP-620

Multifunctional Current Relay for Installation Protection

The EPP-620 current relay is a versatile device designed for monitoring and protecting electrical circuits. Thanks to its four operating functions and adjustable setting thresholds, it provides flexibility in adapting to specific installation needs. DIN TH-35 rail mounting simplifies integration with existing systems. The device is particularly useful in applications requiring precise current control and a quick response to irregularities.

Functionality and Application

The EPP-620 relay works with a current transformer with a secondary current of 5A, allowing measurement of the current value in the circuit. It can operate in four modes, depending on the setting of the FUNC potentiometer, allowing for the implementation of various protection functions – from overcurrent and undercurrent control to hysteresis. Therefore, it finds application both in industrial installations and commercial and residential buildings. It is ideal for protecting against overloads, short circuits and malfunctioning devices.

Technical Characteristics and Construction

The device is characterized by a compact design – it occupies 3 modules on a DIN rail (width 52.5 mm). It has 2x2P switching contacts, which allows for controlling various circuits. Screw terminals with a cross-section of 4.0 mm² guarantee a secure connection of wires. The relay operates at a supply voltage of 230 V AC and offers a maximum load current of R1 and R2 at 8 A each. The housing with a protection degree of IP20 protects against touching and ensures safe operation in standard environmental conditions. Adjustment of the setting thresholds (Imin: 0.02÷1 A, Imax: 0.5÷5 A) and the operating time (T1 and T2: 0÷20 s) allows for precise adjustment of the operating parameters to specific application requirements.
