Product FAQs
7 answersWhat applications are best suited for the K-curve trip characteristic on the SU202M-K30?
The K-curve magnetic trip threshold responds at 10 to 14 times the rated current. This allows the breaker to ride through high inrush currents without nuisance tripping, making it ideal for motors, transformers, and other inductive loads.
Does the SU202M-K30 provide primary branch circuit protection?
Yes. As part of the SU200M series, this breaker is UL 489 listed for branch circuit protection, which allows it to serve as a primary overcurrent device in North American electrical panels.
What is the acceptable wire gauge range for the terminals on this ABB breaker?
The built-in screw and clamp terminals are designed to securely terminate conductors ranging from 18 AWG to 4 AWG.
What type of mounting hardware is required to install this circuit breaker?
The breaker snaps directly onto a standard 35mm DIN rail, requiring no additional mounting brackets or hardware for installation in compatible control panels.
Are ABB System pro M compact accessories compatible with this breaker?
Yes, the SU202M-K30 integrates seamlessly with ABB System pro M compact UL 489 accessories, allowing you to easily add auxiliary contacts, bell alarms, or shunt trips to your DIN rail setup.
Is this breaker suitable for both alternating and direct current circuits?
Yes, it is rated for universal use across both AC and DC systems. It provides a 10kA interrupting capacity at up to 480Y/277VAC as well as 96VDC, ensuring safe fault clearing in either application.
Does the SU202M-K30 feature finger-safe terminals?
Yes, this breaker is designed with IP20 rated terminals to protect electricians and panel builders from accidental contact with live wiring during maintenance and operation.
