Schneider Electric LC1DMKP7 Contactor for Capacitor – 3P 25kVAr 415V Coil 230VAC

The Schneider Electric LC1DMKP7 Capacitor Contactor is a specialized 3-pole contactor designed for switching capacitor banks in power factor correction (PFC) systems. Rated for 25kVAr at 415V, this contactor is engineered to manage the high inrush currents associated with capacitor switching operations.

With a 230VAC control coil, the LC1DMKP7 is suitable for integration into automatic power factor correction (APFC) panels and reactive power compensation systems in industrial and commercial installations.

Unlike standard motor contactors, this capacitor-duty contactor incorporates pre-charge resistors to limit transient currents during capacitor energization, ensuring longer equipment life and improved system stability.
