ACB Panel: Technical Specifications & Product Description
Overview
Our ACB (Air Circuit Breaker) Panels are the backbone of industrial and commercial power distribution systems. Designed for Low Voltage (LV) applications, these panels serve as the primary "Power Control Centre" (PCC), protecting your electrical infrastructure from overloads, short circuits, and earth faults. Engineered for reliability, our panels ensure maximum uptime and safety for high-current applications.

Construction & Build Quality
Enclosure Material: Fabricated from high-quality Cold Rolled Close Annealed (CRCA) steel (1.6mm to 2.0mm thickness).
Surface Finish: Seven-tank pre-treatment process followed by durable epoxy powder coating (Standard RAL 7032/7035 Grey).
Busbar System: Electrolytic grade high-conductivity Aluminum or Copper busbars, sized for low current density and supported by non-hygroscopic SMC/DMC insulators.
Compartmentalization: Fully compartmentalized design to isolate the breaker, busbars, and cable alleys, preventing fault propagation.
Advanced Protection Features
Our ACB panels are equipped with Microprocessor-based Trip Units providing:
Overload Protection (L): Adjustable current settings (0.4×I
n
to 1.0×I
n
) with time delay.
Short-Circuit Protection (S): Selective protection for downstream faults.
Instantaneous Trip (I): Immediate tripping for high-magnitude faults.
Earth Fault Protection (G): Protects against leakage and ground-related hazards.
Anti-Pumping Relay: Prevents the breaker from repeatedly "hunting" or cycling during a persistent fault.
Why Choose Our ACB Panels?
High Selectivity: Designed so that only the breaker closest to a fault trips, preventing a total facility blackout.
Ease of Maintenance: Draw-out versions allow for quick inspection and replacement without de-energizing the entire panel.
Safety Interlocks: Features mechanical and electrical interlocks to prevent accidental door opening or racking while the breaker is "ON."
Compliance: Fully compliant with IS/IEC 60947-1 & 2 standards for low-voltage switchgear.
Applications
Industrial Plants: Cement, Steel, Chemical, and Manufacturing units.
Commercial Infrastructure: Data centers, Hospitals, and Shopping Malls.
Power Utilities: Substation distribution and DG (Diesel Generator) synchronization.
