The Cutler-Hammer BJ2125 is a molded case circuit breaker designed to provide reliable overcurrent protection for industrial and commercial electrical systems. It features a 125A current rating and a 240V AC voltage rating, housed in a compact 6.5" x 2.5" x 3.5" plug-in unit weighing 1.8 lb. This two-pole breaker utilizes a thermal-magnetic trip mechanism for both long-time and instantaneous (LI) protection, is certified to UL 489 standards, and offers a 10kA interrupting capacity at 240V for robust fault protection. Its construction supports copper or aluminum conductors from AWG 2 to 300 kcmil and operates effectively across a temperature range of -25°C to 70°C (-13°F to 158°F), making it suitable for panelboards, switchboards, and motor control centers.
