JB3175 - 175Amp Circuit Breaker

JB3175 - 175Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the small details can determine whether the part fits the job. The JB3175 is a 175A, 3-pole Type JB circuit breaker with thermal-magnetic operation and a non-interchangeable trip unit. Taken together, those details give electricians and maintenance teams the information needed to compare the breaker with an existing unit. When the ratings, dimensions, trip arrangeme "t, and te" minal re" uirements line up, the JB3175 can be considered for form, fit, and functional replacement in compatible legacy equipment.

Key Features and Benefits

• 175A, 3-pole configuration — two basic specifications that should match the breaker being replaced.
• Type JB: It's for compatible equipment requiring this specific type.
• Thermal-magnetic operation matches the JB3175's stated operating design.
• Equipped with a non-interchangeable trip unit.
• Load-side terminals are included, an important point to check when replacing an existing breaker.
