VISHAY MH12N RELAY
- Reactive power compensation in low- and medium-voltage systems
- Power factor optimization in industrial facilities
The ESTAmat MH‑12N operates at 230 VAC ± 10% and can control from 1 to 12 capacitor steps. It provides four-quadrant operation for systems with generators. It features a display of measurement data, an alarm relay for fault signaling, and automatic C/k (capacitance/current) setting. The device offers keypad-driven configuration, parameter locking, and menu-based adjustment.
