ITE JJ2B350 Molded Case Circuit Breaker 600 Volt

ITE JJ2B350 Molded Case Circuit Breaker is a two-pole device rated for 600 volts with a 350 amp current rating, identified by the JJ2B350 part number in the ITE JJ2 family. The two-pole design interrupts current on two conductors to provide overcurrent protection for higher‑current circuits, and its molded case construction houses the internal switching mechanism within an insulated, durable enclosure. The 350 A rating defines the maximum continuous load the device is designed to carry, while the 600 V rating sets the maximum voltage the breaker can interrupt safely. The JJ2B350 designation places this component in the ITE JJ2 series, indicating a standardized high‑current, two‑pole protection device suitable for industrial and commercial electrical installations that require reliable, single-component overcurrent protection.
