Eaton PDC53K1600D5MR Molded Case Breaker - 50kA/415V

Frame 5, three-pole construction, and a 1600 A current rating deliver high-capacity protection for feeder circuits in demanding manufacturing environments. This arrangement reduces nuisance trips by ensuring the protective device coordinates with upstream protection and downstream loads, improving safety during fault events. The unit’s 50 kA breaking capacity at 415 V supports robust short-circuit clearance without sacrificing selectivity in large switchgear. Designed for Eaton's Power Defense family, it fits standard frame 5 assemblies, enabling consistent performance across multiple panels and projects. Modbus RTU communications and built-in relays enable remote signaling, alarm generation, and integration with plant SCADA systems. This visibility supports condition-based maintenance and faster fault diagnosis, reducing mean time to repair. The ARMS LSIG option with PXR20D accelerates safe operation by providing arc protection features that align with modern safety standards. With rear-terminal wiring, field installation is simplified and misconnection risk is reduced during assembly and commissioning. Rear terminals included in the package streamline wiring and shorten installation time, while the compact enclosure helps fit dense control panels. The 629 mm depth, 365 mm height, and 387 mm width give clear space planning guidelines and predictable compatibility with common chassis dimensions. Thermal performance is enhanced by the standard design, enabling stable operation under high-load conditions. This MCCB supports straightforward retrofits for aging installations, reducing downtime during upgrades. Industry reliability and a proven track record reduce lifecycle risk and spare part inventory. By consolidating protection, signaling, and control features in a single device, facilities lower total cost of ownership and simplify maintenance contracts.
