Quick Comparison Guide for Capacitor Duty Contactor Selection from 12.5kVAR to 60kVAR

Physical Selection Logic for Small Compensation Units from 12.5kVAR to 20kVAR

For small compensation branches of 12.5kVAR and 20kVAR, the physical rated current typically ranges between 18A and 29A. Within this physical range, the core task of the Capacitor Duty Contactor is to physically suppress physical inrush currents that can reach up to 100 times the rated current. HertzKron recommends selecting models equipped with 3 pairs of physical leading auxiliary contacts to reduce the physical surge to between 3 and 5 times the rated current through physical pre-insertion resistors. This physical protection ensures that the metallized film of the Power Capacitor does not undergo early physical attenuation due to physical overheating.

Key Physical Selection Factors for Medium Compensation Capacities from 25kVAR to 40kVAR

When the physical capacity increases to 25kVAR, 30kVAR, or 40kVAR, the physical operating current reaches 36A to 58A. At this stage, the physical arc-extinguishing capability of the Capacitor Duty Contactor becomes critical. Since capacitors generate extremely high re-ignition voltages at the physical moment of disconnection, HertzKron solutions utilize a magnetic blow-out structure with faster physical breaking speeds to ensure the physical arc is completely extinguished within 10 milliseconds. For physical working conditions involving frequent switching, it is advised to set a physical safety margin of more than 1.3 times to account for physical voltage fluctuations in the grid.

Advanced Physical Configuration for Heavy Load Compensation Branches from 50kVAR to 60kVAR

In heavy-load physical environments of 50kVAR and 60kVAR, the physical current breaks through 72A or even 87A. A Capacitor Duty Contactor of this grade must possess stronger physical thermal stability and higher-hardness physical silver alloy contacts. To prevent physical contact welding under high-current impact, HertzKron high-capacity models reinforce the physical reaction force of the internal physical springs. Additionally, at this physical power level, the unit must be used strictly in coordination with a Series Reactor to protect the physical output circuits of the Power Factor Controller from electromagnetic physical pulse interference through physical impedance synergy.
