Eaton JGH3175FAG Molded Case Circuit Breaker 175A 3P

Product Description

The EATON JGH3175FAG is a molded case circuit breaker designed for overcurrent protection in commercial and industrial power distribution systems. Molded case circuit breakers of this type provide automatic fault interruption, protecting downstream wiring, equipment, and personnel from overload and short-circuit conditions. The JGH3175FAG is rated at 175 amps and is configured as a 3-pole device, making it suitable for three-phase branch circuit or feeder protection. Licensed electricians install this class of breaker in panelboards, switchboards, and motor control centers where reliable fault protection is required.

This breaker is intended for use in commercial and light industrial electrical distribution applications requiring three-phase overcurrent protection. It fits within the J-frame product family, a common platform used in loadcenters and switchgear assemblies that require higher-ampacity protection beyond standard residential ratings. Typical installations include feeder protection for HVAC equipment, motor loads, and general power distribution panels in commercial facilities.

Key Features

• 175-amp continuous current rating for feeder and branch circuit protection
• 3-pole configuration suitable for three-phase power distribution
• Molded case construction provides durable, self-contained arc interruption
• Thermal-magnetic trip mechanism responds to both overload and short-circuit faults
• Designed for installation in compatible J-frame panelboards and switchboards

Compatibility

Designed as an OEM-style replacement or direct-install molded case circuit breaker for commercial panelboards and switchboards accepting J-frame 3-pole breaker configurations. Consult the panelboard manufacturer documentation to confirm frame and interrupting rating compatibility before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panelboard or switchboard completely before removing or installing any circuit breaker. Verify that the bus stab or line-side connection points are clean and undamaged before seating the breaker. Do not exceed the breaker's rated ampacity with connected load.
