Our Products

VCBs are recommended for primary substation incoming/outgoing feeders where automatic short-circuit fault interruption (up to 40 kA) and rapid auto-reclosing duty are required. Load Break Switches (LBS) are ideal for distribution transformer switching, secondary substations, and ring main units where manual or motor-operated switching under normal load currents with HT fuse short-circuit protection is cost-effective.

APFC panels continuously monitor lagging reactive power (kVAR) and dynamically switch balanced capacitor stages via microprocessor relays to maintain power factor above 0.98. This eliminates electricity board low-power-factor penalties (WBSEDCL, CESC, Tata Power), reduces maximum kVA demand charges, mitigates transformer I²R heating losses, and earns utility power factor rebates.

MOBY's Combined Unit PCC with APFC integrates primary busbars, main incoming Air Circuit Breaker (ACB), outgoing motor/distribution feeders, and capacitor bank stages into a single factory-coupled enclosure. This design saves up to 40% valuable substation footprint, eliminates inter-panel cabling and external busducts, and provides unified single-point testing.

Every dispatch from our Kolkata plant includes comprehensive Routine Test Certificates (dielectric insulation test, contact resistance CRM, breaker opening/closing timing), CPRI Type Test Report references, General Arrangement (GA) drawings, Single-Line Diagrams (SLD), schematic control wiring diagrams, and O&M instruction manuals.

Standard ratings (VCB panels up to 1250A, standard APFC banks) are typically manufactured and routine-tested within 3 to 5 weeks from drawing approval. Large custom-engineered Power Control Centers (PCC), 33kV switchgears, and unitised substations range from 6 to 10 weeks depending on component imports and client drawing sign-off.
