FAQs
When mounting the ER4X-40N3PB, ensure a suitable panel cutout for the enclosure and proper clearance for access to the pistol-style handle. Use appropriate wiring terminals rated for 600 V and 40 A, and confirm compatibility with upstream protection devices since this is a non-fused disconnect. Verify CE compliance and NEMA 4X enclosure integrity for environmental exposure. Adequate locking out during maintenance is recommended to maximize safety.
Key specs are a 600 V voltage rating and 40 A current rating, with a non-fused configuration and a NEMA 4X enclosure, plus CE marking. These specs support medium-power isolation with robust environmental protection, enabling rapid, safe shutdowns during service and reducing downtime due to wiring or enclosure failures. Upstream protection must be coordinated to prevent overcurrent conditions.
Industries with rugged environments and frequent maintenance, such as manufacturing conveyors, presses, machine tools, and outdoor/control panel assemblies, benefit from the ER4X-40N3PB. The 600 V/40 A rating, CE compliance, and NEMA 4X enclosure make it suitable for both indoor and wash-down environments where reliable circuit isolation is critical.
The ER4X-40N3PB is CE marked and features a NEMA 4X rated enclosure, indicating compliance with European regulatory expectations and robust environmental protection. The 600 V/40 A ratings define safe operating limits for mid-range industrial circuits. These certifications and ratings support safer operation, regulatory compliance, and predictable performance in diverse facilities.
The non-fused design reduces fuse-related maintenance and inventory costs, while the pistol-style handle supports ergonomic operation during lockout procedures. The rugged enclosure and CE/NEMA 4X protections help minimize environmental-related downtime. Overall, this translates to safer service windows, faster maintenance cycles, and improved lifecycle reliability for panel builds and OEM projects.
