Air Circuit Breakers (ACB's)
Manage and protect primary low-voltage distribution plants up to 6300A with world-class ABB Air Circuit Breakers (ACB's) supplied by Hagar.
Essential for main distribution boards in mining, manufacturing, and commercial infrastructure across Southern Africa, ABB open breakers provide exceptional fault isolation and power management. Hagar provides genuine ABB Emax 2 ACBs backed by local engineering support and physical stock availability.
Product Overview & Sub-Ranges
ABB Emax 2 Series (E1.2 to E6.2): Compact air circuit breakers functioning as smart power managers, reducing main switchboard footprint sizes while measuring energy usage directly at the breaker.
Fixed vs. Draw-Out (Withdrawable): Available as fixed-type units for permanent busbar mounting, or draw-out variants with guide cradles for rapid maintenance without powering down the full board.
Ekip Microprocessor Trip Units: Touchscreen and digital trip blocks providing comprehensive LSIG protection curves, fault recording, and native Modbus/Ethernet communication modules.

Frequently Asked Questions
What makes the ABB Emax 2 series more advanced than older Emax ACBs?
A Fixed ACB is bolted directly to the switchboard busbars, requiring a complete panel shutdown for major maintenance. A Draw-out ACB sits inside a cradle chassis, allowing maintenance teams to mechanically rack the breaker out for service or replacement within minutes, keeping the rest of the switchboard live and drastically lowering downtime.
What is the difference between a Fixed and a Draw-out (Withdrawable) ABB ACB?
A Fixed ACB is bolted directly to the switchboard busbars, requiring a complete panel shutdown for major maintenance. A Draw-out ACB sits inside a cradle chassis, allowing maintenance teams to mechanically rack the breaker out for service or replacement within minutes, keeping the rest of the switchboard live and drastically lowering downtime.
What functions do ABB Ekip trip units perform on an Air Circuit Breaker?
Ekip microprocessor-based trip units offer highly granular protection parameters including long-time delay (overload), short-time delay (short-circuit), instantaneous trip, and earth fault protection (LSIG protection). Advanced versions feature color touchscreens, power quality analysis, and native Modbus/Profibus communication modules.
What are the typical maintenance requirements for an industrial ABB ACB?
To ensure reliable operation in heavy industrial or marine environments, ABB ACBs should undergo annual inspections. Maintenance tasks include checking contact wear indicators, cleaning dust from the arc chutes, lubricating the internal spring-charging mechanisms, and testing trip-unit functionality using certified electronic injection test kits.
