Intended use: Three-phase installations / Photovoltaic and electrical distribution applications

The operation of the STVP-936VA simultaneously monitors all three phases, displaying voltages V1, V2, V3 and currents A1, A2, A3 separately. If the set voltage or current limits are exceeded, the relay cuts off the load supply to protect the installation. After the parameters return to the normal range, the device allows automatic reconnection of the supply according to the set parameters.

Connection:
Input – upper terminals: N – L1 – L2 – L3
Output – lower terminals: N – L1 – L2 – L3

Designed for three-phase installation with neutral (3P+N). The sequence and position of the terminals must be followed according to the markings on the device.

Installation and safety: Installation is done inside the electrical panel, on a 35 mm DIN rail. Installation, conductor selection, and setting of protection parameters must be performed by authorized personnel, depending on the installation and connected load.

Note: The STVP-936VA is a protection device against voltage fluctuations and overcurrents. It does not replace residual current devices (RCD/RCBO), arc fault detection devices (AFDD), or specific short-circuit protection where these are required in the installation.
