Eaton FDPBT3644J – 200A/200A, 600V, 3-Pole Twin Breaker-Style Fusible Switch – 200kAIC

Eaton FDPBT3644J is a rugged, high-capacity twin breaker‑style fusible switch engineered for demanding industrial and commercial electrical distributions. With dual 200A circuits in a single 3‑pole enclosure, this 600V device delivers reliable, space‑saving power control where every amp counts.

Dual‑circuit protection in one compact enclosure

Designed to protect two critical circuits without expanding the footprint, the FDPBT3644J combines two independent 200A poles in a single, rugged unit. Its twin breaker‑style fusible design provides fast, reliable overcurrent and short‑circuit protection while keeping wiring and layout streamlined in panelboards and switchboards.

Why this matters for your system

• High-energy fault clearance: 200kAIC interrupting capacity at 600V ensures robust protection for demanding distribution networks.
• Space‑efficient architecture: Eliminates the need for separate protective devices, freeing valuable space in crowded electrical rooms.
• Durable construction: Built to Eaton’s FDPBT standards, delivering long service life in harsh industrial environments.
• Seamless integration: Specifically designed for use with Eaton FDPBT series panelboards and switchgear, enabling straightforward upgrades or retrofits.

Ideal applications and use cases

The FDPBT3644J is an excellent choice for panelboards, switchboards, and distribution systems that require reliable dual‑circuit protection within a compact enclosure. It’s particularly well-suited for installations where space is at a premium but high current protection is non‑negotiable, such as:

• Large commercial facilities with dense electrical rooms
• Manufacturing floors and processing plants needing dependable dual‑circuit control
• Process control networks that demand fast fault clearance and minimal downtime
• Retrofits or expansions within existing FDPBT series systems
