FAQs
ER4P-30J3PR is designed to accept fuse type J devices within its enclosed rotary disconnect, aligning with Bussmann series protection. The pistol handle enables safe operation, and the unit’s 600 V, 30 A rating supports typical control circuits. For installation, select matching J fuses, wire per code, and apply lockout/tagout procedures to ensure safe service.
ER4P-30J3PR is rated for 600 V and 30 A, with a NEMA 4P enclosure providing environmental protection. It carries CE marking for European safety compliance and is designed for use with fuse type J, ensuring compatible protection in protected enclosures. The unit features a pistol handle for safe operation and a compact footprint suitable for space-constrained panel installations.
Yes. The NEMA 4P enclosure provides protection against dust, water, and corrosion in harsh environments, including outdoor and damp locations. This rating helps ensure reliability in manufacturing floors and exposed installations, reducing the need for extra enclosure housings. For added protection, pair with proper wiring practices and secure sealing where cables enter the enclosure.
Improved safety comes from the built-in pistol handle and fused isolation, enabling predictable, controlled operation during servicing. The enclosure minimizes exposure to arcs and dust, supporting safer lockout procedures and reduced arc-flash risk. Maintenance is simplified by a compact form factor and compatibility with Bussmann series components, which streamlines fuse replacement and spare-part planning.
Investing in ER4P-30J3PR delivers measurable ROI through improved safety, reduced downtime, and simplified compliance. The CE marked, NEMA 4P-rated enclosure lowers the risk of environmental damage, while the fuse type J protection and pistol handle speed service turnovers. Combined with Bussmann series compatibility, procurement and maintenance costs decrease, and the total cost of ownership improves over typical non-enclosed disconnects.
