Designed to UL 810, IEEE 18 and NEMA CP-1; UL/CSA certifiable. Entogo designs and builds the Automatic Power-Factor-Correction Capacitor Bank in its own factory with a vertically integrated supply chain: this product ships in 12–18 weeks (new UL or CSA certification can extend that, within a guaranteed 36-week worst case), and every Entogo product carries a minimum 36-month manufacturer warranty. This **automatic power-factor-correction capacitor bank** raises the power factor of **480 V**, 60 Hz loads — switching stepped kVAR in and out under a PF controller to cut utility demand and reactive charges and free real capacity in transformers and feeders. Detuned filter reactors (typically 7% or 14%) suppress harmonics and protect the capacitors on VFD-heavy and other non-linear systems. Contactor switching is standard, with thyristor / dynamic switching available where speed and service life matter, in **NEMA 1** indoor or **3R** outdoor enclosures sized to the load. Designed and built to **UL 810**, **ANSI/IEEE 18** and NEMA CP-1 and installed per the NEC, with UL (cULus) / CSA certification available on request. ## Key features - Raises power factor, cuts utility demand / reactive charges and frees real transformer and feeder capacity. - Designed and built to UL 810, ANSI/IEEE 18 and NEMA CP-1, installed per NEC, 60 Hz — UL (cULus) / CSA certification available on request. - Detuned filter reactors suppress harmonics and protect capacitors on non-linear (VFD-heavy) systems. - Automatic PF controller with contactor switching; thyristor / dynamic switching optional for fast, durable response. - NEMA 1 indoor or 3R outdoor; stepped kVAR sized to the load.

An automatic (stepped) bank switches kVAR in and out to match the load. - **Do I need detuned reactors?**: On systems with significant harmonic content (VFDs, rectifiers), detuned filter reactors (typically 7% or 14%) are recommended to suppress harmonics and protect the capacitors. They are available as part of the bank. - **What standards and ratings apply?**: 480 V (240 / 600 V available), stepped kVAR with PF controller, 60 Hz.
