For a 480 V line, it's rated 50 A continuous. That gives you selectivity headroom in a typical 400 V MCC or distribution panel. Terminals are screw-type, accepting 2x (2.5 to 16 mm²) solid or stranded on the main circuit, and up to 70 mm² on a single conductor. The 3RV2021-4NA25 is a smaller-frame SIRIUS breaker (45 mm wide vs 70 mm) with lower breaking capacity — typically 25 kA at 400 V. It won't drop into a panel wired for the 3RV2342-4HC10 without checking terminal lug sizes and fault-current coordination. The 3RV2342-4HC10 handles heavier cable (up to 70 mm² single) and higher prospective fault levels, so it's the right choice where SCCR requirements push above 25 kA.","metaTitle":"Siemens 3RV2342-4HC10 SIRIUS Circuit Breaker, 50 kA at 400 V","metaDescription":"Siemens SIRIUS 3RV2342-4HC10 circuit breaker for starter combinations. 50 kA breaking capacity at 400 V AC.
