Meet the Eaton JDB3100 — a compact, dependable 3‑pole molded case circuit breaker designed to protect your electrical distribution with precision. Rated at 100 A and up to 600 V, this unit is built for reliable branch circuit overcurrent and short-circuit protection in panelboards and load centers.

  • Thermal-magnetic trip unit: delivers stable, repeatable protection by combining thermal overload sensing with magnetic short‑circuit fast‑tripping for rapid interruption during faults.
  • Space-saving molded case design: a compact form factor that minimizes panel depth and frees up precious bus space in panelboards and load centers.
  • 3‑pole configuration: suitable for 3‑phase circuits, ideal for commercial and light industrial applications, while still adaptable for complex residential setups in multi‑wire systems.
  • 600 V rating: supports higher voltage distributions commonly found in commercial and industrial environments.
  • 100 A continuous rating: robust protection for feeders and large branch circuits without nuisance trips.
  • OEM-compatible: engineered to drop into Eaton‑compatible panelboards and load centers for seamless installation and consistent trip characteristics.

Use cases and scenarios

  • Installing or upgrading service panels in small offices, retail spaces, or light industrial workplaces where space is at a premium.
  • Replacing aging breakers in existing Eaton ecosystems to restore full protective coordination across multi‑panel systems.
  • Feeding high‑demand equipment or large branch circuits that require dependable protection against both overload and short circuits.

Why choose the JDB3100 over generic breakers? Its integrated thermal‑magnetic trip unit ensures predictable operation across varying temperatures and loads, reducing nuisance trips while delivering swift response to faults. The molded‑case construction resists impact and provides durable performance in daily service, while the unit's compatibility with OEM load centers means you won't have to rework panel interiors during replacement.
