Application Scenarios

Power factor improvement in AC power systems (rated voltage 1000V).
Voltage quality enhancement.
Suitable for environments with high ambient temperatures and significant system voltage fluctuations.
Requires consideration for harmonic environments; use with anti-harmonic reactors if necessary.
Recommended for use with motors (capacitor current
Should be disconnected when transformers are no-load.

Notes

For phase voltage, divide line voltage by 3 for YN connection.
Models with "YN" indicate phase compensation capacitors with a neutral lead.
Customization for low-temperature environments (-40~+50) is available.
For altitudes above 2000m, consider higher rated voltages (0.48kV for 2000m-3000m, 0.525kV for >3000m).
Specialized switches, contactors, electronic composite switches, and overcurrent relays are recommended for systems with parallel capacitors.
Capacitors require a 3-minute delay before re-energization and must be short-circuited for discharge after power disconnection.
When using miniature circuit breakers for short-circuit protection, select 2-3 times the rated current; avoid closing breakers with capacitors connected. For capacities >30kvar, use RT36 fuses.
