JDF36250 - 250Amp Circuit Breaker

JDF36250 - 250Amp Circuit Breaker

The JDF36250 has a specific checklist: 250 amps, three-pole, J-Frame construction, thermal-magnetic protection, and busbar connections on both the line and load sides. That makes those details especially useful when you're trying to identify the right breaker for an existing distribution setup. The JDF36250 is built to last, but selection should still be based on matching the breaker to the equipment's electrical, connection, mounting, and dimensional requirements.

Key Features and Benefits

• 250A, three-pole configuration: Gives you clear starting points for checking compatibility with existing distribution equipment.
• Thermal-magnetic protection: Provides both overload and short-circuit protection.
• Busbar connections on both sides: The line and load sides use busbar connections, an important detail when checking physical fit.
• 2500A magnetic trip current: The manufacturer also specifies a 1250A magnetic hold current.
• 80% continuous current rating: Provides another defined electrical characteristic to verify against the application.
• Push-to-trip button: Built into the cover for manual breaker tripping.
• Dual-break rotating contacts: Designed to reduce peak current during a short-circuit fault.

Where It Works Best

The JDF36250 is a practical fit for compatible distribution equipment calling for a 250A, three-pole J-Frame circuit breaker with thermal-magnetic protection and busbar connections. Because both the line and load sides use busbar connections, that's one detail you'll want to check closely when matching it to an existing installation.
