JDA36150 - 150 Amp Circuit Breaker

JDA36150 - 150 Amp Circuit Breaker

The JDA36150 is a 150A, three-pole PowerPacT J-frame circuit breaker with an I-Line connection on the line side and mechanical lugs on the load side. That connection arrangement is an important detail when you're checking a replacement against equipment already in service. For existing and legacy installations requiring this exact J-frame and I-Line arrangement, the JDA36150 is built to last. It provides clearly documented specifications for a careful form, fit, and function replacement.

Key Features and Benefits

• 150A, three-pole configuration: Provides the specific current rating and pole arrangement required by compatible equipment.
• I-Line construction: Uses an I-Line line-side connection with a bracket mounting arrangement, a key compatibility point for existing I-Line applications.
• Thermal-magnetic trip unit: Provides manufacturer-specified overload and short-circuit protection.
• Load-side mechanical lug: Uses an AL175JD terminal that accepts both aluminum and copper conductors.
• Defined conductor range: Accommodates 4 AWG through 4/0 AWG aluminum or copper at the specified load-side terminal.
• ABC phase connection: Manufacturer documentation identifies the phase arrangement as ABC.
• Push-to-trip function: An integral push-to-trip button allows the breaker to be manually tripped.

Material Compliance and Certifications

The JDA36150 carries UL, CSA, and NOM product certifications and is CE marked. Manufacturer documentation also identifies applicable standards including UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2. These documented certifications and standards provide useful verification when matching the breaker to equipment with specific compliance requirements.

Where It Works Best

The JDA36150 is suited to compatible existing and legacy I-Line equipment that specifically requires a 150A, three-pole PowerPacT J-frame circuit breaker with thermal-magnetic protection. Its combination of an I-Line line-side connection and load-side mechanical lug is particularly important when evaluating physical and electrical compatibility. The manufacturer also identifies the breaker as HACR-rated, making it another specification to consider where required by the application.
