Current relay with through-channel, contacts: 1P, Imax=16A, DIN rail mounting, 1 module EPP-619

Current relay for precise load control

The EPP-619 current relay is a reliable device designed to monitor and protect electrical circuits from overload. Using the relay allows for precise control of the current value, which translates to increased safety and reliability of the installation. Thanks to its compact size (1 module) and mounting on a TH-35 rail, integration with existing infrastructure is simple and fast.

Functionality and application

The device is single-function, meaning it focuses solely on controlling the current in the circuit. It has a through-channel for the current-carrying wire, allowing direct measurement of the current intensity. The relay reacts to exceeding the set current threshold, switching the contact and signaling an alarm state. Thanks to the adjustable setpoint (0.6…16A) and time delay (0.5…10s), the relay's operation can be adapted to the specific requirements of the application. This is particularly important for devices with motors that generate high starting currents – the C characteristic allows it to react more slowly to short current surges, tolerating the starting of such devices.

Advantages for installers and users

• Compact dimensions: Occupies only 1 module on a TH-35 rail, saving space in the switchboard.
• Adjustable setpoint: Allows precise adjustment to specific loads and application requirements.
• Through-channel: Facilitates current measurement without the need for additional measuring elements.
• Optical indication: An LED indicates the power supply status and exceeding the setpoint.
• Versatility: Suitable for applications in residential, commercial and industrial buildings.
• Screw terminals: Ensure a secure and durable connection of wires (2.5 mm²).
• Wide supply voltage range: Operation at 230V AC ensures compatibility with most electrical installations.

The EPP-619 relay protects the circuit against overload and short circuit — like most circuit breakers in this class, but offers the additional functionality of precise current monitoring. This makes it possible to detect potential problems early and prevent equipment failure or damage to the electrical installation.
