Product FAQs
7 answersWhat types of loads is the K-curve on the SU202M-K0.5 designed to protect?
The K-curve characteristic is specifically engineered for loads with high inrush currents, such as motors and transformers. It allows the breaker to ride through momentary startup surges by tripping at 10 to 14 times the rated current, preventing nuisance tripping while maintaining strict branch circuit protection.
Is the ABB SU202M-K0.5 approved for branch circuit protection?
Yes, the SU200M series is UL 489 listed, meaning it is fully certified for branch circuit protection in North American electrical systems, unlike UL 1077 supplementary protectors.
What applications typically require a 0.5A circuit breaker?
A 0.5 Amp breaker like the SU202M-K0.5 is typically used for protecting highly sensitive control circuits, small transformers, sensors, or specialized instrumentation that requires precise low-current protection.
What mounting standard does the SU202M-K0.5 require?
This miniature circuit breaker snaps onto a standard 35mm DIN rail, making it ideal for high-density industrial control panels and automation enclosures.
Can I use ABB System pro M compact accessories with this breaker?
Yes, the SU202M-K0.5 is fully compatible with ABB System pro M compact UL 489 accessories. This allows you to easily integrate bottom-fitted auxiliary contacts, shunt trips, and bell alarms into your panel design.
What is the correct wire size for the terminals on the SU202M-K0.5?
The failsafe bi-directional cylinder-lift terminals accept solid or stranded conductors from 18 AWG up to 4 AWG, and busbar connections from 18 AWG to 8 AWG.
Does the SU202M-K0.5 provide visual trip indication?
Yes, it features a real Contact Position Indication (CPI) window directly connected to the moving contact, displaying a clear green (OFF) or red (ON) signal to verify the exact status of the circuit.
