Reliable film capacitors
for PFC systems

The GRIDCAP series consists of self-healing metalized polypropylene film (MKP) capacitors manufactured to IEC 60831-1&2 standards. Designed specifically for power factor correction panels, GRIDCAP capacitors work in conjunction with GRIDTUNE detuned reactors and CSM100 thyristor modules to form complete GRIDFIX compensation systems.

With nominal voltages from 230V to 900V and power ratings from 5 to 40 kvar, GRIDCAP covers all standard industrial voltage levels. Available in three connection types — Delta (D) for 3-phase systems, Star/Wye (Y) for 800V and 900V configurations, and Parallel (P) for single-phase or 230/250V applications.

Self-healing technology ensures continued operation after minor dielectric breakdowns. Epoxy resin filling provides moisture and vibration resistance. RoHS compliant, mercury-free, non-PCB construction meets all current environmental regulations.

Safety — stored energy

A power capacitor holds a dangerous charge after disconnection. Wait at least 5 minutes after switching off and verify zero voltage before touching the terminals. Short-circuit and earth the terminals before any work.

GRIDCAP has an internal discharge device that brings the residual voltage to ≤ 75 V within 3 minutes, per IEC 60831-1. The 5-minute figure above is the safety margin used on the product label. Installation and service by qualified personnel only.

Leave room above the unit. When the over-pressure disconnector operates the can expands by up to 30 mm. Leave at least 40 mm free space above each capacitor inside the panel.

Expected Operating Life

Temperature vs. Service Life

Hotspot temperature directly affects capacitor life. Lower temperatures significantly extend service life.

Hotspot TemperatureExpected Life
≤ 40°C≥ 100,000 hours
45°C≈ 70,000 hours
50°C≈ 50,000 hours
55°C≈ 35,000 hours
Note: Ensure adequate ventilation inside PFC panels. Every 10°C reduction in hotspot temperature approximately doubles expected capacitor life.
Selection Guide

Voltage & Connection Selection Guide

Choose the correct voltage and connection type based on your system configuration.

Voltage CodeNominal VoltageConnectionTypical Application
230230VP (Parallel)Single-phase, 230V systems
250250VP (Parallel)Single-phase, 250V systems
440440VD (Delta)Standard 400V industrial (most common)
480480VD (Delta)480V export / US standard
525525VD (Delta)Use with p=7% detuned reactor at 400V
800800VY (Star)Use with p=14% detuned reactor at 400V
900900VY (Star)Use with p=7% detuned reactor at 525V
Note: When using detuned reactors, the capacitor voltage must be higher than the network voltage to compensate for the voltage drop across the reactor. 525V capacitors are standard for p=7% detuned systems at 400V networks.
