Eaton CH2100ST - 100 A, 240 V, 2-Pole Plug-In Circuit Breaker | AmpState

Introducing the Eaton CH2100ST 100 A, 240 V, 2-pole plug-in molded case circuit breaker — a dependable, fast-acting line of defense for your electrical system. Specifically designed for panelboards and loadcenters, this breaker delivers reliable overcurrent and short-circuit protection where it matters most, backed by Eaton’s trusted engineering and AmpState’s expert stocking.

Key advantages that matter in real-world wiring projects

• Fast plug-in connection enables quick installation and painless replacements, minimizing downtime on service calls or panel upgrades.
• Thermal-magnetic trip unit provides stable, repeatable protection by reacting to both sustained overloads and instantaneous short-circuit events, helping protect wiring and connected equipment from damage.
• 100 A, 240 V, 2-pole configuration is ideal for main or feeder protection in residential, commercial, and light industrial applications, handling typical load centers with ease.
• Plug-in molded case design simplifies maintenance and future upgrades by allowing straightforward insertion into compatible OEM loadcenters.
• OEM compatibility ensures coordinated performance with matching Eaton loadcenters and panelboards, reducing fitment concerns and trip curve mismatches.

What problems does the CH2100ST solve?

When a panel requires immediate protection against overcurrent and short circuits, the CH2100ST provides a reliable, reproducible trip profile that electricians can count on. Its plug-in form reduces installation time and service interruption, while the thermal-magnetic mechanism delivers predictable behavior across a range of temperatures and loads — a practical advantage in both new installations and panel refurbishments.
