Square D EGB34035 35A 480V 3-pole Bolt on Circuit Breaker

Product Description

The SQUARE D EGB34035 is a 3-pole miniature circuit breaker rated for 35 amps at 480Y/277 volts, designed for bolt-on panel installation in commercial and industrial electrical distribution systems. It carries a 35 kA interrupting (breaking) capacity, making it suitable for higher-fault-current environments where standard residential breakers would not meet code. The lug terminal connection type accommodates 12 and 14 AWG conductors. Licensed electricians install this breaker during new construction, panel upgrades, or breaker replacement service calls.

The EGB34035 is intended for use in commercial and light industrial applications where 480Y/277-volt three-phase power distribution is present. Typical installations include lighting panels, motor branch circuits, and multi-wire branch circuits in office buildings, warehouses, and manufacturing facilities. Its bolt-on mounting style secures the breaker directly to the bus bar, reducing the risk of breaker movement under fault conditions compared to plug-in styles.

Key Features

• 35-amp continuous current rating with 35 kA breaking capacity for high-fault-current panels
• 480Y/277-volt rating covers three-phase commercial distribution systems
• 3-pole configuration for simultaneous disconnect of all three phases
• Bolt-on mounting for secure, vibration-resistant bus bar connection
• Lug terminal connection compatible with 12 and 14 AWG wire

Compatibility

Designed as an OEM-style bolt-on replacement miniature circuit breaker for compatible SQUARE D loadcenters and panelboards accepting EGB-series breakers in 480Y/277-volt three-phase configurations.

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 panel before removing or installing any circuit breaker. Verify the panel bus bar accepts bolt-on style breakers before installation. Confirm conductor AWG and insulation rating match the breaker and termination requirements before landing wires on the lug terminals.
