JJA36175 - 175 Amp Circuit Breaker

JJA36175 - 175 Amp Circuit Breaker

A useful place to start with the JJA36175 is its 1750A magnetic trip current and 875A magnetic hold current. Those figures help identify the trip characteristics, but they are only part of the compatibility check. The breaker measures 7.5 inches high, 4.09 inches wide, and 3.4 inches deep, giving you another set of numbers to compare with the existing installation. The JJA36175 is built to last and is suited for form, fit, and functional replacement where its J-Frame construction, I-Line mounting, ratings, connections, and dimensions match the equipment already in service.

Key Features and Benefits

• 175A, 3-pole configuration provides a clear starting point for checking electrical compatibility.
• I-Line line-side connection is an important fit and mounting detail for compatible I-Line equipment.
• Mechanical lugs on the load side use the AL175JD terminal.
• 4 AWG–4/0 AWG conductor range accommodates aluminum or copper conductors within the specified range.
• Thermal-magnetic trip technology provides overload and short-circuit protection.
• 80% continuous current rating with an ABC phase connection.
• Integral push-to-trip function provides manual breaker tripping from the cover.

Where It Works Best

The JJA36175 is suited to compatible existing and legacy distribution equipment that calls for a 175A, three-pole PowerPacT J-Frame breaker with an I-Line line connection and load-side lugs. The AL175JD terminal and 4 AWG–4/0 AWG conductor range are especially useful details to verify when checking a replacement.
