FAQs
Install the ER12-63N6SR as the main or sectional service disconnect within the control panel, ensuring the mounting pattern matches your enclosure and that conductors are properly sized for 63A and 600V. Verify the selector is accessible and the fuse class L protection is coordinated with the downstream protection scheme. Follow CE-compliant wiring practices and secure protective covers after wiring.
Key specs include catalog number ER12-63N6SR, 63A amperage rating, 600 V maximum voltage, NEMA 12 enclosure, fuse class L compatibility, selector feature, and CE marking. The unit is designed for 63A circuit protection with a robust enclosure suited for industrial environments. Verify the UPC 051712414906 for procurement and cross-reference with your BOM.
Yes, the ER12-63N6SR utilizes a NEMA 12 enclosure, which provides protection against dust and light splashes typical in industrial settings. While it offers solid protection for many environments, for washdown or extremely harsh conditions you may need additional enclosure ingress protection. Always align enclosure ratings with the specific facility conditions.
This unit is ideal for industrial control panels, motor control centers, and service disconnects in automated lines, conveyors, and packaging equipment. Its 63A, 600V rating supports medium-load circuits, while the selector and fuse class L compatibility streamline protection coordination. It works well wherever reliable isolation and quick maintenance access are required.
The ER12-63N6SR reduces downtime by enabling safe, rapid maintenance isolation and straightforward fuse coordination with class L protection. Its CE-compliant design and NEMA 12 enclosure help minimize environmental-related faults, lowering maintenance costs and improving overall uptime in automated facilities. This translates to faster service routines and more predictable production availability.
