Siemens VL Molded Case Circuit Breakers utilize a compact and modular design which can be configured to suit a wide range of ratings from 30 A up to 1600 A. Designed for global requirements, most breakers include the world's major standards and markings such as UL, CSA, NOM, IEC, CE and CCC. At 480 VAC, VL Circuit Breakers feature N-Class (35 kA), H-Class (65 kA) and L-Class (100 kA) interrupting ratings. They also feature both thermal magnetic and electronic trip units across the entire product line, assuring compatibility for virtually any application. VL Trip Units measure true RMS current. This type of measurement ensures the most accurate means of measuring currents in today's harmonic filled electrical distribution systems.
