Eaton Specification Sheet - BG3021B
Amperage range of 1–20 A provides flexible protection for a variety of control circuits, reducing the need for oversizing and inventory. This directly translates to lower material costs and improved protection accuracy, especially in compact panels. The 100 kAIC short-circuit rating strengthens fault tolerance, safeguarding downstream components and reducing repair downtime after faults. A 600 V voltage rating expands suitability across typical industrial controls and automation panels, enabling universal applicability in machine builders and panel shops. Class G construction delivers reliable interruption performance, while box lug connections simplify wiring and ensure durable, vibration-resistant terminations in harsh environments. The BG3021B’s RoHS compliance and UL/CSA certifications relieve compliance risk for global deployments and end-user approvals. Its compatibility with the BG Bussmann series supports easy spares, fast replacements, and streamlined maintenance in serviceable control environments.
