FAQs
The ER4X-030CC3PR is designed for secure mounting within standard electrical panels or equipment enclosures. Plan for enough clearance to operate the red pistol handle and to perform fuse replacement safely. Consider maintaining recommended DIN rail or chassis mounting clearances plus 2–3 inches of ventilation around the enclosure to avoid overheating and facilitate future maintenance.
This switch is rated for 600 V and 30 A, with a 50/60 Hz frequency rating and a three-pole configuration. These specs support typical motor starter, contactor, and control circuit isolation tasks in industrial panels. The Class CC fuse protection aids in fast, predictable interrupting while maintaining coordination with downstream protection devices.
Yes. The unit carries a NEMA 4X enclosure rating, which provides protection against rain, splashing water, and corrosion in damp or washdown environments. This makes it well-suited for outdoor switchgear, food and beverage processing areas, and other harsh industrial settings where reliable isolation is required.
The product is CE marked and listed to UL/cUL standards, with UL 98 certification noted and cULus listed (pending). These certifications support compliance in many regulatory environments, streamline third‑party audits, and validate safety for control panels, reducing risk during procurement and installation.
The enclosed design minimizes contamination risk, reducing maintenance frequency. Class CC fusing together with a pistol handle enables faster fuse replacement, lowering downtime costs. The durable NEMA 4X enclosure and robust electrical ratings help extend service intervals, delivering lower lifecycle costs and predictable performance in demanding automation environments.
