Siemens NGB3B060B Molded Case Circuit Breaker

Siemens NGB3B060B is a 60-amp, three-pole molded-case circuit breaker from Siemens’ NGB/VL family, designed for low-voltage distribution in commercial and light-industrial panels. It provides thermal-magnetic protection with long-time and instantaneous trip functions, and includes load-side lugs for panelboard wiring. Rated for 600Y/347 VAC operation in three-phase systems, it carries UL489 listing and an interrupting capacity of 14 kA at 600Y/347 VAC, making it suitable for circuits where fault currents are within that range; the unit mounts in standard panelboards and accepts copper or aluminum conductors through the included lugs (Cu: 4 AWG – 2/0, Al: 6 AWG – 1/0). Its compact 3-pole form measures roughly 6.9 in long, 4 in wide, and 4.7 in high, and is suitable for reverse-feed configurations in some installations.
