Frequently Asked Questions
Q: What's the difference between NEMA Size 2 and Size 3 starters?
A: NEMA Size 3 starters like the CBRCI2-N3-3R-HB handle larger motors (up to 50HP @ 480V) compared to Size 2 (up to 25HP @ 480V). Size 3 also provides higher continuous current rating (90A vs 45A).
Q: Can I use this starter for single-phase motors?
A: No, the CBRCI2-N3-3R-HB is designed specifically for 3-phase motors. For single-phase applications, consider our single-phase motor starter options.
Q: What does Class 20 overload protection mean?
A: Class 20 means the overload relay will trip in 20 seconds at 600% of the motor's full-load current. This is ideal for high-inertia loads that require longer acceleration times.
Q: Is this starter suitable for outdoor installation?
A: Yes, the NEMA 3R enclosure provides protection against rain, sleet, and windblown dust, making it suitable for both indoor and outdoor installations.
Q: Can I add remote control capabilities?
A: Yes, the auxiliary contacts can be used for remote control integration with PLCs or other control systems. The 110/120V control circuit is compatible with most automation systems.
