ABB E212323 Two-Pole Molded Case Circuit Breaker

ABB E212323 Two-Pole Molded Case Circuit Breaker is a UL 489-listed two-pole protection device from ABB’s S200/SU200 family, engineered for branch-circuit protection in 277Y/480 VAC systems at 50/60 Hz with up to 10 kA interrupting capacity. The UL file E212323 covers models such as SU200M, SU200MR, and S200UDC, whose current ratings span roughly 0.2–63 A and offer trip curves K, C, and Z to match motor-start and general-protection needs. These DIN-rail-mountable molded-case breakers are designed for industrial control panels, providing simultaneous disconnection of both lines in a 277Y/480 VAC distribution and compatibility with ABB mounting accessories and interconnects. The E212323 two-pole variant supports 277Y/480 VAC service and 50/60 Hz operation, aligning with typical commercial and light-industrial panel protections. As part of ABB's DIVQ family and UL-listed protection solutions, these breakers offer dependable overcurrent protection within compact footprints and can be paired with other DIVQ/MCCB components to form integrated protection schemes.
