Fan Favorite Siemens NGG3B030 – 30A 3 Pole Molded Case Circuit Breaker

Built for heavy-duty power distribution, the Siemens NGG3B030 is a 3-pole, 30A MCCB from the Sentron GG frame lineup. It utilizes a reliable thermal-magnetic trip mechanism to deliver LI protection against overloads. Designed for flexibility, this breaker mounts into control panels and DIN rail enclosures. It features nut keeper plates instead of standard lugs, allowing for custom lug kits or reverse-feed setups. Rated 25 kAIC at 480VAC, it is replaced by the newer 3VA5130-4ED31-0AA0.
