Eaton GBH2030 - 30 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Eaton GBH2030 is a rugged, two-pole 30A, 600V bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and loadcenters. Built to withstand real-world electrical environments, it combines a secure mounting method with precise protection for peace of mind in every installation.

Key differentiators that matter in the field

• Secure bolt-on mounting: A robust bolt-on connection creates a rigid, vibration-resistant bus interface, reducing movement that can lead to arcing or loose connections in demanding locations like equipment rooms, garages, or commercial spaces.
• Thermal-magnetic trip unit: Combines thermal overload protection with instantaneous magnetic trips for short circuits, delivering stable, repeatable protection curves across temperature fluctuations and load conditions.
• OEM-ready compatibility: Designed to pair with matching Eaton OEM load centers and panelboards, ensuring coordinated protection, electrical characteristics, and reliable fitment during replacements or upgrades.
• Versatile applications: Ideal for residential panels, commercial electrical setups, and light industrial installations where dependable branch-circuit protection is essential.
• Clear, proven design: A molded-case construction built for long-term reliability in continuous operation, with clear signaling of trips to simplify troubleshooting and maintenance.

Why it solves real problems

Overcurrent and short-circuit events can cause downtime, equipment damage, or safety hazards. The GBH2030 targets these risks with a dual-action trip system that responds quickly to faults while maintaining predictable behavior during normal use. Its bolt-on mounting minimizes movement and connection wear, helping you avoid intermittent trips and nuisance faults that plague looser, plug-in styles. For technicians, this means fewer service calls and faster panel upgrades without sacrificing protection quality.
