JJL36250 - 250 Amp Circuit Breaker

JJL36250 - 250 Amp Circuit Breaker

At 250 amps, the JJL36250 has a specific set of electrical and connection details worth checking against the breaker already in place. It’s a three-pole PowerPacT J circuit breaker with a thermal-magnetic trip unit, a 2500A magnetic tripping current, and a 1250A magnetic hold current. The JJL36250 is built to last and is a practical choice when your existing or legacy distribution equipment requires this combination of amperage, trip characteristics, lug connections, and physical dimensions.

Key Features and Benefits

• 250A, three-pole design for compatible PowerPacT J distribution equipment.
• Uses a thermal-magnetic trip unit for overload and short-circuit protection.
• Lugs on both ends make the line- and load-side connection arrangement easy to confirm.
• AL250JD terminals accept 3/0 AWG through 350 kcmil aluminum or copper conductors.
• Carries an 80% continuous current rating.
• HACR rated as specified by the manufacturer.

Material Compliance and Certifications

The JJL36250 carries UL, CSA, and NOM certifications and is CE marked. Published standards include UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2. The front cover is rated IP40, and the specified pollution degree is 3 under IEC 60947-1.

Where It Works Best

The JJL36250 is suitable for situations where the existing distribution equipment calls for a 250A, three-pole PowerPacT J breaker with thermal-magnetic protection and lug connections at both ends. For replacement work, the AL250JD terminal designation, conductor range, trip values, interrupting ratings, and breaker dimensions provide several useful points for comparison with the unit being replaced.
