ACB & MCCB
At Amtech Power, we specialize in the complete SITC (Supply, Installation, Testing & Commissioning) of ACB (Air Circuit Breaker) and MCCB (Molded Case Circuit Breaker) panels, designed to enhance the reliability and safety of electrical distribution networks. ACBs, ideal for medium-voltage applications, offer high breaking capacities up to 6300A and are used in mission-critical systems that demand quick fault clearance. MCCBs serve low-voltage environments with protection up to 1000A, suitable for a wide range of commercial, industrial, and residential needs.
Our ACB & MCCB panels are deployed in diverse infrastructures including manufacturing plants, office buildings, substations, utility projects, and mixed-use developments. We offer end-to-end project execution—from load assessment, custom panel design, OEM-based supply (Siemens, ABB, Schneider, L&T), and robust installation to IS/IEC-compliant testing, operator training, and post-installation support.
Key benefits of our solutions include high operational safety, energy efficiency, flexible current protection, and reduced maintenance downtime. With a focus on delivering certified systems that meet global standards, we also provide Annual Maintenance Contracts (AMC) to ensure long-term performance and support. Whether upgrading existing panels or setting up new systems, our experienced engineering team ensures seamless, on-time delivery with reliable after-sales service.
What are ACB & MCCB?
We specialize in the Supply, Installation, Testing & Commissioning (SITC) of high-quality Air Circuit Breaker (ACB) and Molded Case Circuit Breaker (MCCB) panels for new and existing electrical distribution systems.
Where are ACB & MCCB Used?
Air Circuit Breaker (ACB) is a medium-voltage device used to protect electrical circuits by quickly and safely interrupting overloads and short circuits using air as the arc-quenching medium. It is preferred for applications requiring higher current ratings and breaking capacities and is available in maximum ratings up to 6300A.
Molded Case Circuit Breaker (MCCB) is a low-voltage circuit breaker used for protecting circuits up to 1000A. MCCBs provide reliable protection for smaller loads with adjustable trip settings, ideal for industrial, commercial, and residential applications.
