JGA36250 - 250 Amp Circuit Breaker

JGA36250 - 250 Amp Circuit Breaker

The JGA36250 is a robust 250A three-pole PowerPacT J-Frame circuit breaker designed for durability and reliability. Its combination of ratings makes it easy to identify and select for your various applications. Ideal for compatible distribution equipment, this circuit breaker is tailored to fit specific electrical ratings, physical dimensions, I-Line construction, and terminal configurations.

Key Features and Benefits

• 250A, three-pole design: A clearly defined configuration for compatible distribution equipment.
• I-Line connection on the line side: An important physical and electrical detail when checking fit with an existing installation.
• Load-side mechanical lugs: AL250JD terminals accept 3/0 AWG through 350 kcmil aluminum or copper conductors.
• Thermal-magnetic protection: Provides overload and short-circuit protection without an electronic trip unit.
• 80% continuous-current rating: Clearly specified for this breaker configuration.
• Integral push-to-trip button: Allows the breaker to be manually tripped from the cover.

Where It Works Best

This breaker belongs in compatible existing and legacy distribution equipment that calls for the JGA36250's particular J-Frame and I-Line arrangement. The 250A rating is only one part of that check. Line-side I-Line construction, load-side AL250JD lugs, three-pole layout, conductor range, physical dimensions, and interrupting ratings should all agree with the requirements of the equipment being serviced.
