JJA36225 - 225 Amp Circuit Breaker

JJA36225 - 225 Amp Circuit Breaker

The JJA36225 has a few identifiers worth checking closely before you put it against an existing breaker. On the line side, it uses an I-Line connection. The load side is different, using an AL250JD mechanical lug that accepts 3/0 AWG through 350 kcmil aluminum or copper conductors. The JJA36225 is built to last and is compatible with existing and legacy distribution equipment when the electrical, connection, and physical specifications align with the original application.

Key Features and Benefits

• 225A, 3-pole configuration for compatible distribution equipment requiring these exact ratings.
• I-Line connection on the line side provides an important compatibility point when sourcing a replacement.
• AL250JD mechanical lug on the load side accepts 3/0 AWG through 350 kcmil aluminum or copper conductors.
• Thermal-magnetic trip technology provides overload and short-circuit protection.
• 80% continuous current rating with an ABC phase connection.
• Integral push-to-trip button allows the breaker to be manually tripped from the cover.

Where It Works Best

The JJA36225 is a fit for compatible existing and legacy distribution equipment that calls for a 225A, three-pole J-Frame breaker with an I-Line connection at the line side and a mechanical lug at the load side. The AL250JD terminal designation and 3/0 AWG–350 kcmil conductor range are particularly useful details when checking an existing installation.
