Guide
Air Circuit Breakers (ACB) buying guide
What's in this range
- ABB SACE Emax 2 Air Circuit Breakers – E1.2 to E6.2 frames from 630 A to 6300 A.
- Siemens SENTRON 3WA Air Circuit Breakers – fixed and draw-out breakers at 690 V.
- Siemens SENTRON 3WT8 Air Circuit Breakers – 3-pole and 4-pole breakers at 500 V.
- ACB Accessories & Releases – rating plugs, auxiliary contacts and partitions.
How to choose
- Rated current of the frame, matched to the transformer or incomer load.
- Breaking capacity (Icu) at the system voltage, above the prospective short-circuit current.
- Fixed or draw-out version: draw-out allows maintenance without opening the busbar.
- Trip unit: Ekip or ETU, with LI, LSI or LSIG protection functions for selectivity.
- Poles: 3P or 4P according to the neutral arrangement. Standard: IEC 60947-2.
FAQ
Air Circuit Breakers (ACB) questions
When is an ACB needed instead of an MCCB?
Typically for main incomers and bus ties above 1000 A to 1600 A, and where selectivity and draw-out maintenance matter.
What does LSI mean on an ACB trip unit?
LSI stands for long-time, short-time and instantaneous protection, which allows time-based selectivity between breakers.
Do you ship air circuit breakers worldwide?
Stoklink ships worldwide from Turkey on EXW terms. Lead time depends on distributor stock, so request a quote with your part numbers and quantities.
