Heavy-duty three-phase AC distribution boards built for large commercial and utility-scale solar installations, from 30kW right up to 300kW. Each unit combines high-capacity overcurrent protection — C-Curve MCBs on smaller ratings, 4-pole MCCBs on larger ones — with Type-2 40kA surge protective devices and a No-Volt Release (NVR) switch that safely disconnects the system on under-voltage and prevents unsafe auto-restart.
Every board is housed in a rugged IP65-rated powder-coated metal enclosure with RYB phase indicators and isolators, and built with L&T and Elmex components. As capacity rises, the breaker rating scales with it — so whatever the size of your plant, the protection is matched to the load.
Supplied in bulk to EPCs, installers, and developers across India, with custom configurations available on request. Message us on WhatsApp with your system size for the right capacity and a bulk quote.

FAQs:
- What capacities are available? From 30kW to 300kW — see the capacity table above. Tell us your system size and we’ll supply the right one.
- When does it use an MCB vs an MCCB? Smaller ratings (up to ~35kW) use C-Curve MCBs; from 40kW upward the higher currents require 4-pole MCCBs.
- What is the NVR switch? A No-Volt Release that safely disconnects the system on under-voltage and prevents unsafe automatic restart.
- What surge protection is included? Type-2 40kA SPDs on every unit.
- Is it suitable for outdoor installation? Yes — IP65-rated powder-coated metal enclosure, built for Indian conditions.
- Can I order in bulk or get a custom configuration? Yes — we supply in bulk pan-India and offer custom configurations. Message us on WhatsApp.
