The 209-3-1-62-4-8-30 is a three-pole, E-Frame hydraulic-magnetic circuit breaker that combines power switching and overcurrent protection. This UL 489 listed device is rated for 30A at a maximum of 240Vac, 50/60Hz. It features a series trip configuration with a medium time delay (Delay 62) suitable for mixed loads, and is equipped with 10-32 stud terminals for back panel mounting. The hydraulic-magnetic operating principle ensures that trip characteristics remain stable and unaffected by ambient temperature changes. It is ideal for branch circuit applications such as EDP, air conditioners, panel boards, and lighting controls.
