JGL36250 - 250 Amp Circuit Breaker

JGL36250 - 250 Amp Circuit Breaker

The electrical label tells you a lot about the JGL36250: 250 amps, three-pole, thermal-magnetic protection, and interrupting ratings up to 18 kA at 600 VAC. Just as useful for replacement work are the connection details. This PowerPacT J-Frame circuit breaker has lugs on both the line and load sides, with AL250JD terminals accepting 3/0 AWG through 350 kcmil aluminum or copper conductors. The JGL36250 is built to last and is a practical form, fit, and functional replacement when its ratings, lug arrangement, conductor range, and dimensions match the equipment already in service.

Key Features and Benefits

• 250A, 3-pole configuration: Clearly defined electrical characteristics for matching compatible distribution equipment.
• Line- and load-side lugs: Lug connections are provided at both ends of the breaker.
• Thermal-magnetic protection: Provides overload and short-circuit protection.
• AL250JD terminals: Accommodate 3/0 AWG through 350 kcmil aluminum or copper conductors.
• Defined magnetic characteristics: 2500A magnetic tripping current with a 1250A magnetic hold current.
• 80% continuous-current rating: An important specification to verify when matching the breaker to the intended system.
• Integral push-to-trip: Provides a manual method for tripping the breaker from the cover.

Material Compliance and Certifications

The JGL36250 is CE marked and carries UL, CSA, and NOM product certifications. Manufacturer-listed standards include UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2. The front cover is rated IP40, with a pollution degree of 3 per IEC 60947-1.

Where It Works Best

The JGL36250 is suited to compatible existing and legacy distribution equipment that calls for a 250A, three-pole PowerPacT J-Frame breaker with lug connections at both the line and load sides. The AL250JD terminal specification and the 3/0 AWG–350 kcmil aluminum/copper conductor range provide additional details to verify connection compatibility.
