JGA36225 - 225 Amp Circuit Breaker

JGA36225 - 225 Amp Circuit Breaker

With the JGA36225, the line and load connections are important for identifying the correct breaker. This 225A, three-pole PowerPacT J-Frame model uses an I-Line connection on the line side and mechanical lugs on the load side. The AL250JD terminal accepts 3/0 AWG through 350 kcmil aluminum or copper conductors. An integral push-to-trip button is included, and the breaker carries an 80% continuous-current rating. The JGA36225 is built to last and provides a well-documented set of electrical, connection, and dimensional specifications to verify compatibility with your existing and legacy distribution equipment.

Key Features and Benefits

• 225A, three-pole design: A specific configuration for distribution equipment requiring this current rating and pole count.
• I-Line line-side connection: Helps identify the correct mounting and connection arrangement when replacing an existing breaker.
• Mechanical load-side lugs: Uses an AL250JD terminal for 3/0 AWG through 350 kcmil aluminum or copper conductors.
• Thermal-magnetic protection: Provides overload and short-circuit protection.
• Defined magnetic characteristics: 2250A magnetic trip current with a 1125A magnetic hold current.
• 80% continuous-current rating: Clearly documented for comparison with the requirements of the existing electrical system.
• Integral push-to-trip button: Allows the breaker to be manually tripped at the device.

Material Compliance and Certifications

The JGA36225 is UL, CSA, and NOM certified and carries a CE mark. Applicable standards listed for the breaker include UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2. Its front cover is rated IP40, and the specified pollution degree is 3 under IEC 60947-1.

Where It Works Best

The JGA36225 is suitable for applications where the existing distribution equipment requires a 225A, three-pole PowerPacT J-Frame I-Line circuit breaker with this particular connection arrangement. The I-Line line connection is especially important here, as is the load-side AL250JD lug setup for 3/0 AWG through 350 kcmil aluminum or copper conductors.
