Explore Panel Types
Main Distribution Board (MDB)
Primary power distribution from transformer to sub-circuits. Rated up to 6300A. Houses main incoming breaker, bus-section, and outgoing feeders.
Power Control Center (PCC)
High-capacity power distribution for industrial facilities. Controls and distributes incoming power to MCC, APFC, and downstream loads.
Motor Control Center (MCC)
Centralized motor control with starters, contactors, overloads, and VFDs in standardized withdrawable/fixed functional units.
Power Factor Correction Panel (APFC)
Automatic capacitor switching for reactive power compensation. Thyristor or contactor-switched, detuned or standard configurations.
Automatic Transfer Switch (ATS) Panel
Automatic changeover between mains and generator/UPS. Open or closed transition, with or without bypass.
Variable Frequency Drive (VFD) Panel
Enclosed VFD assemblies with input protection, line reactors, EMC filters, output reactors, and bypass options.
Generator Control Panel
Genset start/stop sequencing, synchronization, load sharing, and paralleling controls.
Metering & Monitoring Panel
Energy metering, power quality analysis, and multi-circuit monitoring with communication gateways.
Lighting Distribution Board
Final distribution for lighting and small power. MCB/RCBO-based with DALI or KNX integration options.
Busbar Trunking System (BTS)
Prefabricated busbar distribution per IEC 61439-6. Sandwich or air-insulated, aluminum or copper.
PLC & Automation Control Panel
Process and machine control panels housing PLCs, I/O modules, relays, HMIs, and communication infrastructure.
Custom Engineered Panel
Bespoke panel assemblies for non-standard requirements — special ratings, unusual form factors, multi-function combinations.
Soft Starter Panel
Enclosed soft starter assemblies for reduced voltage motor starting with torque control, ramp-up/down profiles, and bypass contactor options.
Harmonic Filter Panel
Active or passive harmonic filtering to mitigate THD from non-linear loads. Tuned LC filters, active filters, or hybrid configurations.
DC Distribution Panel
DC power distribution for battery systems, solar installations, telecom, and UPS applications. MCCB/fuse-based DC protection.
Capacitor Bank Panel
Fixed or automatic capacitor bank assemblies for bulk reactive power compensation in industrial and utility applications.
