Product FAQs
5 answersWhat applications is the K trip curve on the SU202M-K16 designed for?
The K curve provides an instantaneous trip at 8 to 14 times the rated current. It is specifically designed for industrial control panels, motor feeders, and circuits with high inrush currents like transformers or switch-mode power supplies. This prevents nuisance tripping while maintaining sensitive cable protection.
Is the SU202M-K16 rated for branch circuit protection?
Yes, the ABB SU200M series is UL 489 listed. This means the breaker is fully approved for primary branch circuit protection in US electrical panels, unlike UL 1077 devices which are only rated as supplementary protectors.
How does the ABB SU202M-K16 mount inside an electrical panel?
This miniature circuit breaker snaps directly onto a standard 35mm DIN rail. It is designed for modular enclosures and industrial control panels that utilize DIN rail mounting systems.
What wire sizes are accepted by the terminals on this 16A breaker?
The conductor terminals accept wire gauges from 18 AWG up to 4 AWG. If you are using a busbar connection, the terminals accommodate 18 AWG to 8 AWG.
Can the SU202M-K16 be used in DC power circuits?
Yes, this 2-pole breaker is rated for up to 96VDC applications. This makes it suitable for DC control circuits and power distribution in addition to its standard AC voltage ratings.
