JDA36225 - 225 Amp Circuit Breaker

JDA36225 - 225 Amp Circuit Breaker

The JDA36225 is a 225A, three-pole PowerPacT J-frame circuit breaker with an I-Line connection on the line side and an AL250JD mechanical lug on the load side. That connection arrangement is an important checkpoint when matching a breaker to existing I-Line equipment. At 7.5 inches high, 4.09 inches wide, and 3.4 inches deep, the physical dimensions give you another useful reference when checking fit. The JDA36225 is built to last, and its defined electrical, connection, and dimensional specifications make it suitable for form, fit, and functional replacement where this exact breaker configuration is required.

Key Features and Benefits

• 225A, three-pole configuration: Provides the specified current rating and pole arrangement for compatible equipment.
• Thermal-magnetic trip technology: Provides overload and short-circuit protection without adding unnecessary complexity to the replacement specification.
• I-Line line-side connection: Uses I-Line construction with bracket mounting.
• AL250JD load-side lug: Mechanical load connection accepts 3/0 AWG to 350 kcmil copper or aluminum conductors.
• 250VDC capability: Manufacturer specifications also provide a 20 kA interrupting rating at 250VDC.
• ABC phase connection: Manufacturer documentation specifies an ABC phase arrangement.
• Integral push-to-trip button: Allows manual tripping of the breaker.

Material Compliance and Certifications

The JDA36225 carries manufacturer-specified UL, CSA, and NOM product certifications and is CE marked. Applicable standards identified in the product documentation include UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2. The breaker is also specified as suitable for isolation in accordance with IEC 60947-2.

Where It Works Best

The JDA36225 is suited to compatible existing and legacy I-Line electrical equipment requiring a 225A, three-pole J-frame thermal-magnetic circuit breaker with the stated electrical ratings. The connection arrangement is particularly important here: the line side uses an I-Line connection, while the load side is fitted with an AL250JD mechanical lug.
