Description
Part of the S200UP series, this thermal-magnetic breaker delivers reliable branch circuit protection for commercial and industrial environments. It installs easily into standard DIN rail control panels and features finger-safe screw terminals for secure wiring. Rated for 10kA interrupting capacity at 480Y/277V, the K-curve trip profile is optimized to handle high inrush currents typical of motors and transformers. Note that this specific model has been superseded by the SU202M-K5.Specifications

Product FAQs
6 answersWhat does the K-curve designation on the S202UP-K5 mean for my application?
The K-curve thermal-magnetic trip unit is designed to handle high inrush currents without nuisance tripping. It trips between 10 and 14 times the 5A rated current, making it ideal for protecting motors, transformers, and other inductive loads.
Does the ABB S202UP-K5 meet UL standards for branch circuit protection?
Yes, breakers in the ABB S200UP series are UL 489 listed. This means the S202UP-K5 can be used for primary branch circuit protection in North American electrical panels, unlike UL 1077 supplementary protectors.
How is the S202UP-K5 installed in a control panel?
This miniature circuit breaker snaps directly onto a standard 35mm DIN rail. Its modular design allows for quick installation and integration alongside other DIN-mounted components in control panels and enclosures.
Can I use the S202UP-K5 in DC circuits?
Yes, in addition to its 480Y/277V AC rating, this breaker is rated for up to 125V DC, providing versatile overcurrent protection for both alternating and direct current control circuits.
Is the S202UP-K5 compatible with standard ABB accessories?
Yes, as part of the System pro M compact series, the S200UP frame is compatible with a wide range of modular ABB accessories, including the S2C-H6RU auxiliary contact, S2C-S6RU bell alarm, and S2C-A series shunt trips.
What type of wire connections does the S202UP-K5 support?
The breaker features screw/clamp terminals that accommodate 18 to 4 AWG conductors. These finger-safe terminals provide secure feed-thru connections for control wiring.
