ABB S5N E93565 Molded Case Circuit Breaker With Trip Unit

ABB S5N molded‑case circuit breaker with trip unit, E93565, is a three‑pole MCCB rated at 300 A designed to protect three‑phase electrical circuits in industrial power distribution. This ABB device belongs to the S5N family and includes a trip unit that automatically interrupts current during overload or fault conditions, helping safeguard motors, transformers, and downstream wiring. The unit carries UL file E93565 for circuit breakers and MCPs, indicating alignment with recognized safety standards for protective devices. With a compact form factor typical of ABB MCCBs, the S5N E93565 provides reliable switching and protection in panelboards and switchgear assemblies, enabling safe isolation and coordination with upstream protections. For precise electrical ratings beyond the stated 300 A, available trip options, mounting configurations, terminal types, and interrupting capacity, refer to the official ABB data sheet or catalog entry specific to the E93565‑listed S5N variant.
