FAQs
To install the ER3R-030CC2PR, first ensure the panel location supports a NEMA 3R rated enclosure. Confirm compatibility with Bussmann series Class CC fuses and prepare the mounting surface for a two-pole disconnect with a pistol-style red handle. Mount the unit securely, wire per the electrical rating (600 V, 30 A), and verify proper lockout/tagout procedures before commissioning.
The ER3R-030CC2PR is rated for 600 V and 30 A, operates at 50/60 Hz, and is a two-pole device with a Class CC fuse configuration. It corresponds to a NEMA 3R enclosure and uses a pistol-style handle. It is designed to pair with Bussmann series Class CC fuses for safe, coordinated protection in control circuits.
Yes. The unit carries a NEMA 3R rating, which provides weather-resistant protection suitable for outdoor or semi-exposed environments. While it is certified for indoor use as well, its enclosure design is optimized for outdoor service alongside standard control-panel installations in industrial settings.
This model is CE marked and cULus listed, with UL 98 certification noted as pending. These certifications indicate conformity with European and North American safety standards, supporting risk mitigation, regulatory compliance, and supplier qualification in global procurement operations.
The pistol-style red handle provides intuitive, fast operation and enhances operator safety during lockout. Class CC fuse configuration ensures coordinated overcurrent protection with compatible Bussmann fuses, simplifying selection, improving fault isolation, and reducing maintenance time in panel assemblies.
