FAQs
The JGS3175FAGA1 fits standard MCCB panels designed for three-phase protection and accepts line and load terminals. It uses a JG frame and is compatible with enclosures that accommodate a 9.25 in depth and 5 in width/height footprint. For field wiring, rely on the rear auxiliary switch with a 48 in right-hand pigtail to streamline installation.
The JGS3175FAGA1 provides 35 kAIC at 480 Vac, 18 kAIC at 600 Vac, 40 kAIC at 415 Vac, and 85 kAIC at 240 Vac. This range supports robust short-circuit protection across voltage strata, enabling selective coordination and reduced fault energy in mixed-volt applications.
Wire through the line and load terminals with the device mounted for three-pole operation. Use the fixed adjustable trip (T185) to set protection thresholds appropriate for your load profile. Include the 1A-1B auxiliary contact wired to the control circuit via the 48 in right-hand pigtail for status signaling and coordinated control.
Yes. The JGS3175FAGA1 is designed for control panels with three-phase protection and adjustable trip coordination. Its JG frame supports reliable motor feeding, while the high interrupt ratings and rear pigtail wiring enable precise coordination with downstream protective devices, reducing nuisance trips and downtime in machine centers.
