Square D EGB36035 - 35 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Square D EGB36035—a 3-pole, 35A, 600V bolt-on molded case circuit breaker engineered for dependable branch circuit protection in panelboards and loadcenters. From AmpState, this unit blends rugged construction with precise protection, making it a solid choice for professional electrical installations where reliability matters as much as performance.

Why this breaker stands out

• Secure bolt-on mounting: a rigid bus connection that resists vibration and maintains solid electrical contact over time, reducing the risk of loose connections and nuisance trips.
• Thermal-magnetic trip unit: combines a thermal element for slow, predictable overload protection with an instantaneous magnetic trip for fast interruption during short circuits—delivering stable, repeatable protection under diverse load conditions.
• OEM-compatible design: engineered to pair with matching Square D loadcenters and panelboards for straightforward, plug-and-play replacement or retrofits without compromising enclosure integrity.
• Three-pole configuration: ideal for three-phase systems, distributing fault current across all phases to protect equipment and wiring in commercial and light industrial applications.
• Molded case construction: compact, rugged housing that provides reliable insulation and protection in service entrances, control panels, and distribution boards.

What problems does it solve?

This breaker is purpose-built to prevent damage from overloads and short circuits in electrical panels. The bolt-on design minimizes connection quality issues common with field replacements, while the thermal-magnetic trip mechanism ensures fast, decisive action on faults and smooth, predictable response under normal operation. With 600V ratings, it’s capable of handling higher-voltage distribution schemes found in commercial and light-industrial environments, giving you a dependable, long-term protection solution.

Applications and use cases

Ideal for places where sturdy, reliable feeder protection is essential, including:

• Panelboards and loadcenters in light commercial settings such as offices, retail spaces, and service areas.
• Three-phase distribution circuits requiring robust fault protection up to 600V.
• Retrofits or replacements in existing Square D installations where a bolt-on, 3-pole device is required.
• Branches feeding motors, transformers, or other critical equipment where quick interruption during faults minimizes downtime.
