Eaton LDCB3350 Molded Case Circuit Breaker - UL 489

The LDCB3350 is a three-pole, L-frame complete molded case circuit breaker designed to fit compact industrial panels while delivering robust protection for motor control and distribution applications. Feature → Business Impact → Application: The three-pole configuration and L-frame geometry minimize panel footprint while enabling reliable trip coordination across three-phase systems; this reduces wiring complexity and speeds installation in control panels and switchboards. Feature → Business Impact → Application: Fixed thermal and fixed magnetic trip (T186) provide fast, predictable protection against overloads and short circuits, lowering unplanned downtime and extending motor life in manufacturing lines. Feature → Business Impact → Application: High interrupt ratings—100 kAIC at 480 Vac and 200 kAIC at 240 Vac—allow safe operation in high fault-current environments such as distribution centers and machine rooms, reducing risk of cascading failures. Feature → Business Impact → Application: UL 489 certification ensures regulatory compliance and audit readiness, simplifying procurement and integrating with other UL-listed MCCBs in a standardized protection scheme. Feature → Business Impact → Application: Aluminum line and load terminals deliver durable, corrosion-resistant connections with straightforward torque requirements, supporting quick field assembly and reliable long-term performance. Feature → Business Impact → Application: Compatibility with Series C accessories and common MCCB ecosystems enables plug-in adapters and modular upgrades, reducing total cost of ownership and enabling scalable protection architectures. Feature → Business Impact → Application: The warranty and Eaton support ecosystem provide confidence in maintenance planning, minimizing downtime during component replacements and service events.
