The two-pole, 300 A LDB2300W uses a fixed thermal and magnetic trip (T186) to deliver reliable overcurrent protection with fast interruption, increasing line reliability and reducing unplanned downtime in critical processes. This translates to measurable business value by protecting motors and feeders from overloads while minimizing nuisance trips in dynamic load scenarios. As part of the Series C, the L-frame complete breaker design enables straightforward panel installation and predictable mounting, supporting consistent field performance across multiple enclosure types. Compatibility with StrandAble terminals and plug-in adapters (as documented in Eaton MCCB literature) simplifies retrofit projects and spare-part planning, lowering total cost of ownership. The unit’s UL 489 certification reinforces compliance during audits and helps streamline procurement and engineering reviews. In industrial automation applications, the Eaton LDB2300W integrates smoothly with MOEM MCCB guides for accurate time-current coordination.

FAQs

LDB2300W is a two-pole, complete MCCB designed as a complete breaker without terminals. To connect conductors, plan for compatible terminal accessories or StrandAble/plug-in adapters as documented in Eaton’s MCCB literature. Confirm enclosure clearance and mounting compatibility with the Series C L-frame to ensure proper fit and wiring clearance in your panel.
At 240 V, the interrupt rating is 65 kAIC; at 480 V, it is 35 kAIC. It is a two-pole device with a 300 A amperage rating and a fixed thermal-magnetic trip (T186), suitable for protecting feeder and motor circuits within the 50/60 Hz electrical environment.
Yes. As a Series C complete MCCB with a robust 300 A rating, fixed trip and UL 489 certification, it provides reliable overload and short-circuit protection for distribution panels and machine-control circuits in industrial automation environments.
The LDB2300W is certified under UL 489, which is the standard safety certification for molded case circuit breakers. This certification supports safe operation, enhances audit readiness, and aligns with common electrical distribution compliance requirements in North America.
