About Merlin Gerin Air Circuit Breaker

Air Circuit Breaker or ACB is a specially designed electronic device that can function in air in the form of an arc extinguishing medium at a set atmospheric pressure. These circuit breakers that can deliver overcurrent & short-circuit protection mostly find use in low voltage applications (below 450V). Our Air Circuit Breaker based on sophisticated technology are easy to install and deliver reliable performance as compared to the oil circuit breakers. These ACBs we offer come with adjustable trip characteristics.

Versatile Protection for Industrial Needs

Merlin Gerin Air Circuit Breakers are engineered for comprehensive protection against overloads, short-circuits, and as disconnecting switches. The optional digital display and communication interface allow seamless monitoring and integration into modern control systems, supporting dynamic operations in various industrial setups.

Enhanced Safety and Reliability Features

With mechanical endurance up to 10,000 operations and electrical endurance up to 5,000 cycles, this breaker ensures long-term reliability. Adjustable temperature and current protections, multiple mounting options, and optional auxiliary contacts further increase operational safety, making it suitable for diverse electrical distribution environments.
