FAQ
How do I choose the right ABB circuit breaker size?
Start with system voltage, available fault current, continuous load, and conductor sizing. Select amperage and trip characteristics that protect wiring/equipment without nuisance trips. For motors, breaker choice must coordinate with starter/overload settings and inrush. If you’re unsure, use your application’s load data and code requirements.
How do I size an ABB contactor for a motor?
Size by motor horsepower/kW at the system voltage and the duty category (e.g., AC-3 for standard motor starting). Confirm coil voltage, number of poles, and whether you need auxiliary contacts. For frequent starts or harsh environments, consider derating and enclosure ventilation.
What’s the difference between a contactor and a motor starter?
A contactor switches power. A starter typically includes a contactor plus overload protection (and sometimes disconnect/fusing). Starters protect the motor from sustained overload conditions; contactors alone do not.
What’s the difference between a disconnect switch and a circuit breaker?
A disconnect is primarily for isolation; a breaker is for protection and interruption of fault current. Some disconnects are fused or rated for specific duties. Verify the device’s ratings and whether it’s intended for motor circuits, branch circuits, or isolation only.
Are ABB electrical products UL listed?
Many ABB components are UL listed/recognized, but it varies by product and configuration. Always verify the certification markings on the product and in the datasheet—especially when accessories or field modifications are involved.
What are typical lead times for ABB electrical products?
Lead times vary by series, frame size, and accessories. Many common parts ship quickly, while special configurations can take longer. The fastest path is ordering the exact catalog number and confirming stock status on the product page. Call Centro to confirm lead times. We may can get your product expedited.
