Product FAQs
7 answersWhat applications are best suited for the K-curve trip characteristic on this breaker?
The K-curve is designed for loads with high inrush currents, such as motors and transformers. It allows current peaks of 10 to 14 times the rated current without nuisance tripping, while still providing rapid disconnection during a short circuit.
Is the ABB SU202M-K4 rated for branch circuit protection?
Yes, the SU200M series is UL 489 listed. This makes it suitable for primary branch circuit protection in North American applications, unlike UL 1077 supplementary protectors.
How is the SU202M-K4 circuit breaker mounted in a control panel?
This miniature circuit breaker is designed for quick and secure installation on a standard 35mm DIN rail.
What type of wire terminals does the SU202M-K4 feature?
It features failsafe bi-directional cylinder-lift terminals. These terminals accept solid, stranded, or flexible conductors from AWG 18 to AWG 4, as well as busbar connections.
Can the SU202M-K4 be used in direct current applications?
Yes, this breaker is certified for both AC and DC use. It supports protection up to 96VDC, making it versatile for various control circuits.
Does this breaker provide a visual indication of its contact position?
Yes, it features a real Contact Position Indication window that displays green for OFF and red for ON. This indicator is directly connected to the moving contact for reliable safety verification.
Are auxiliary contacts and accessories compatible with the SU202M-K4?
Yes, this breaker is fully compatible with ABB System pro M compact UL 489 accessories. This includes auxiliary contacts, bell alarms, and shunt trips.
