Eaton ER12-30N3PB Enclosed Rotary Disconnect - NEMA 12
Part Number: ER12-30N3PB
Quick Summary
The Eaton ER12-30N3PB enclosed rotary disconnect switch safely isolates circuits up to 600 V and 30 A in industrial panels. For maintenance teams, bulky or nonstandard disconnects can slow down line changeovers and increase downtime risk. This unit meets CE marking and NEMA 12 enclosure requirements while delivering a compact, non-fused solution. Its pistol-style handle enables ergonomic operation in control panels, supporting safer, faster re-energization and lockout workflows. Designed for panel builders and machine operators, it integrates with the Eaton Bussmann series hardware for reliable, code-compliant installations. This translates to reduced spare parts, faster commissioning, and improved incident response in critical manufacturing environments. Trust in a datasheet-supported rating of 600 V, 30 A, CE compliance, and NEMA 12 enclosure to meet rigorous industrial standards.
