GHB3015 Cutler-Hammer Molded Case Circuit Breaker 3-Pole 15A 480Y/277V G-Frame Bolt-On

The GHB3015 is a molded case circuit breaker rated 15A at 480Y/277VAC, listed to UL 489 standards for use in commercial panelboards and electrical assemblies. This G-frame thermal-magnetic circuit breaker features non-interchangeable trip units providing permanent long-time and instantaneous overcurrent protection. Engineered by Cutler-Hammer (Eaton), it operates efficiently at a 50/60 Hz frequency and carries a maximum DC rating of 125/250VDC.

At Essential Parts, we offer fast shipping, lowest price, and expert support to help you get the right product every time. This bolt-on premium electrical component delivers a fixed 14 kAIC interrupting rating at 480Y/277VAC and 65 kAIC at 240VAC. It satisfies precise commercial bid submittals and engineering specifications, utilizing factory-installed standard load lugs rated for copper and aluminum conductors.

Common Applications

• Eaton Powerline commercial panelboard branch circuit protection.
• Industrial machinery electrical assemblies and EOEM integration.
• Commercial HVAC infrastructure and lighting distribution branch circuits.

Key Features

• Thermal-Magnetic Trip: Utilizes a calibrated bi-metal element for long-time overloads and a fixed magnetic coil for high-speed short-circuit clearing.
• Bolt-On Mounting: Heavy-duty bolt-on line tab mechanical connection ensures physical bus stability and reliable conductivity.
• Blow-Open Design: Features a high-speed contact separation configuration that limits downline thermal and mechanical stress.
• Three-Pole Configuration: Provides synchronized, simultaneous common-trip disconnection across all three phase conductors.
