DuraCap SD—Single-Phase Cylindrical Capacitor
DuraCap SD—Single-Phase Cylindrical Capacitor
One family, every duty class. Engineered with self-healing MPP technology, triple safety protection (notch shield + overpressure disconnector + internal protection), and long service life, Elcosine cylindrical capacitors deliver reliable power factor correction across every industry — from small single-phase loads to the harshest harmonic-rich environments. Non-PCB, IEC/IS compliant, and proudly Made in India.
- DuraCap SD — Single Phase | 1–10 kVAr | 250V/415V, 50Hz — Compact and maintenance-free, purpose-built for lighting circuits, pumps, and small motors. IS 2993 compliant with continuous duty design.
DuraCap HD — Cylindrical Capacitor
The DuraCap HD is a three-phase MPP cylindrical capacitor with self-healing technology, built for reliable power factor correction in normal industrial loads (up to 10% non-linear content). With 35,000 switchings/year, 120,000 operating hours, and triple safety protection — it delivers long, trouble-free service in flour mills, rice mills, oil mills, cold storage, and glass industries.
