Eaton CVS2125 Molded Case Circuit Breaker - 42 kAIC
Part Number: CVS2125
Quick Summary
CVS2125 is a molded case circuit breaker that provides tenant main protection in electrical panels and switchgear. Engineers often grapple with selecting devices that meet high fault currents while fitting limited cabinet space. This unit carries CSA Std. C22.2 No. 5 and UL 489 certifications, supporting safe, recognised performance in industrial environments, and it aligns with Eaton's CV frame for straightforward cross-reference in project specs. The two-pole, 125 A rating, and 42 kAIC interrupt capability deliver reliable upstream protection for feeders and distribution circuits. Its compact footprint—7.5 in long, 5 in high, and 3.5 in wide—plus a 2.75 lb weight simplify installation and inventory. The CVS2125 is ideal for tenant protection in power distribution panels, motor control centers, and service equipment.
