FAQs
ER1-40N3PR is designed for indoor control panels with a compact footprint and a pistol-style operating handle. It supports straightforward wiring connections and can be integrated with standard Bussmann series components. Its non-fused design focuses on isolation, and the unit is suitable for simple panel installations and routine maintenance without requiring complex interlocks.
The ER1-40N3PR is rated for 40 A and 600 V, non-fused. This means it can safely interrupt and isolate medium-voltage control circuits and motor loads within that current and voltage range. It is intended for safe disconnection rather than overload protection, so fuse protection should be provided elsewhere in the circuit where necessary.
Yes. With a 40 A rating and a NEMA 1 enclosure, ER1-40N3PR is well-suited for indoor panel boards, switchgear, and motor control centers in manufacturing environments where compact size and reliable isolation are critical. CE marking supports international procurement, and the pistol handle enables ergonomic operation during frequent cycling.
ER1-40N3PR carries CE marking for European compliance and a NEMA 1 enclosure rating for indoor protection. These specifications align with typical control panel and switchgear standards in many regions, aiding cross-border sourcing and regulatory alignment for electrical protection and isolation equipment.
The non-fused, pistol-handled design reduces replacement part complexity and downstream maintenance costs. Its straightforward installation and reliable isolation performance help minimize downtime in routine maintenance and panel upgrades, delivering measurable ROI through improved safety, shorter outages, and easier operator training.
