ACDB 3 Phase — MCB SPD (12 to 20kW) — L&T + Siemens

 Industrial-grade IP65-rated 3-Phase AC Distribution Board with 4-Pole C-Curve MCBs (32A/40A) and Type-2 40kA Surge Protective Devices — engineered for high-capacity transient suppression and overcurrent safety in 12kW to 20kW solar PV systems.

Inquiry

A robust three-phase AC distribution board designed for the higher current loads of 12kW to 20kW solar inverters. It pairs high-rating 4-pole C-Curve MCBs (32A/40A) with Type-2 40kA surge protective devices across all three phases and neutral, delivering the overcurrent capacity and surge protection larger commercial systems demand. Built with L&T MCBs and Siemens protection components, and housed in a rugged IP65 enclosure with cable glands and clear warning labelling, it’s made to sit outdoors through heat, dust, and monsoon. Supplied in bulk; custom configurations on request.
