The Schneider Electric JT3150 model is engineered to be a powerful circuit breaker, capable of managing substantial current levels of 600 amps. This device supports a supply voltage of 600 volts, both in AC and DC. With three poles, it efficiently provides circuit protection while allowing for surface mounting installation. The breaker’s NEMA 3R rating ensures its durability in various environments, including outdoor applications.
Safety features include a fusible disconnect that helps mitigate risks during fault conditions. The short circuit current ratings vary based on the type of fuse used, achieving a rating of 10 kA for H or K fuses and 200 kA for R or J fuses. When it comes to wiring configurations, this circuit breaker is designed for a 4-wire system, which includes three-phase conductors and a neutral line.
Users can work with a wide range of wire sizes, from AWG 3/0 up to 500 kcmil, accommodating both copper and aluminum wiring. The device requires a tightening torque of 375 in-lb (42.4 N.m) for secure connections. Overall dimensions are as follows: 10.13 inches (257.30 mm) in depth, 27.88 inches (708.15 mm) in width, and 50.31 inches (1277.87 mm) in height, with a total net weight of 201.06 pounds (91.2 kg). Additionally, the circuit breaker comes with a factory-installed neutral and can support motor applications up to 500 horsepower at 600 V AC.
