People Electric · Self-healing Shunt Capacitor
Product overview
People Electric BSMJ self-healing low-voltage shunt capacitors are used to improve network power factor. The required kvar must be selected for the actual circuit voltage, load and harmonic conditions. This page covers the detailed rectangular three-phase delta versions in the manufacturer specification tables.

The published selectors cover only the fully tabulated 400V/450V, 50Hz, three-phase delta configurations. Cylindrical Y variants, star-neutral versions, other voltages and other series on the shared source page require separate exact specifications. Total capacitance is the catalogue total, not a per-phase value. Confirm protection, switching, discharge and reactor coordination before ordering.
Typical applications
- Power-factor correction in suitably designed low-voltage three-phase distribution.
- Replacement rectangular shunt capacitors requiring an exact voltage, kvar, connection and mounting match.
