Product FAQs
6 answersWhat applications are best suited for the K trip curve on this breaker?
The K trip curve is engineered for circuits with high inrush currents, such as motors and transformers. It features a higher magnetic trip threshold to prevent nuisance tripping during equipment start-up while maintaining strict thermal overload protection.
Which accessories are compatible with the SU202M-K50?
This breaker is fully compatible with ABB System pro M compact UL 489 accessories. This includes modular add-ons like auxiliary contacts, bell alarms, and shunt trips designed specifically for the SU200M line.
How are the wire and busbar connections configured on this breaker?
The SU202M-K50 features compression terminals that accept 18 AWG to 4 AWG wire for standard conductors. It also includes a dedicated connection point for busbars that accepts 18 AWG to 8 AWG, streamlining panel assembly.
How does the thermal-magnetic trip unit operate during a fault?
The thermal-magnetic mechanism provides two distinct layers of protection. A temperature-sensitive bimetal element bends to open the contacts during a sustained overload, while a current-sensitive magnetic release trips instantaneously to clear short circuits.
Is this breaker rated for primary branch circuit protection?
Yes, the SU200M series is UL 489 listed. This certification allows the SU202M-K50 to be used for primary branch circuit protection in North American installations, distinguishing it from UL 1077 supplementary protectors.
Does this breaker feature a visual contact position indicator?
Yes, the SU202M-K50 includes a clear Contact Position Indication window. It displays red or green to visually confirm the open or closed status of the breaker contacts, enhancing safety during maintenance.
