JGF36250 - 250Amp Circuit Breaker

JGF36250 - 250Amp Circuit Breaker

For the JGF36250, the busbar connection is one of the details worth checking first. This 250A, three-pole PowerPacT J-Frame circuit breaker uses busbar connections on both the line and load sides, providing a clearly defined mounting and connection arrangement for compatible distribution equipment. The JGF36250 is built to last and is well-suited for form, fit, and functional replacement when these specifications match your existing system.

Key Features and Benefits

• 250A, three-pole configuration: Provides a clearly defined current and pole arrangement for compatible distribution equipment.
• Busbar line and load connections: Both sides use busbar connections, an important detail when confirming physical and electrical compatibility.
• Thermal-magnetic protection: Provides overload and short-circuit protection using the specified thermal-magnetic trip technology.
• Defined magnetic trip characteristics: Features a 2500A magnetic tripping current and 1250A magnetic hold current.
• 80% continuous-current rating: Gives you another important specification to verify against the requirements of the existing system.
• Integral push-to-trip: Provides a convenient way to manually trip the breaker from its cover.
