Eaton ED3100L - 100 A, 240 V, 3-Pole Circuit Breaker | AmpState

When you need reliable branch-circuit protection for panelboards and loadcenters, the Eaton ED3100L delivers. This 100 A, 240 V, 3-pole molded case circuit breaker is engineered for steady, repeatable protection in residential, commercial, and light industrial settings. Available from AmpState.

Why the ED3100L stands out

• Compact molded case design optimizes panel space without compromising protection, allowing you to fit more circuits in tight electrical enclosures.
• Thermal-magnetic trip unit provides stable, predictable response to overloads and short circuits, reducing nuisance trips and ensuring reliable performance when it matters most.
• Three-pole configuration delivers synchronized protection across three conductors, ideal for balanced distribution and multi-wire branch circuits in modern panelboards.
• OEM compatibility is designed to pair with matching Eaton loadcenters and panelboards, helping maintain warranty coverage and streamlined field service.
• Versatile applications suited for residential, commercial, and light industrial projects where dependable overcurrent and short-circuit protection is essential.

Real-world use cases

• Protecting main or feeder circuits in new or retrofit panels where space is at a premium and reliable trip performance is non-negotiable.
• Safeguarding critical equipment in small offices, retail spaces, or light manufacturing environments where downtime is costly.
• Providing consistent protection for loads that require a dependable 100 A, 240 V, 3-pole solution in three-phase or multi-wire configurations.

How it protects and why it matters

The ED3100L’s thermal-magnetic trip mechanism combines two protective elements: a thermal element for overload protection and a magnetic element for instantaneous short-circuit response. This means:

• Overloads are detected and cleared with calibrated sensitivity, reducing wear on downstream equipment.
• Short circuits trigger a rapid, decisive trip, helping prevent damage to wiring, devices, and downstream protections.
• Consistent trip performance under varying ambient conditions supports safer, more predictable electrical systems.
