Safety• J Performance in a small “Touch Safe” Package 30 and 60 Amp Class “J” Fuseholder Innovations in Fuseholder Design • Small Compact Design • Touch Safe, meets IP 20 Standard • Dual Port wire management system (30A) • Integral 35 mm DIN Rail Adapter • Gangable – one piece system • Fuse installed external to circuit Bussmann ® No matter how you look at it, Features & Benefits 1. Compact Design: Saves valuable panel space. 2. Touch Safe Design: Protects employees from direct or indirect contact with live parts (meets IP-20). 3. Dual-Port Wire Management System: Simplifies installation of multiple loads connected to a single branch circuit. (30A only) 4. Integral 35mm DIN Rail Adapter: Provides convenient mounting means, built in. 5. One Part Gangable System: Reduced inventory, there’s no need to stock multiple part numbers. One part number is used to make any combination of multiple pole blocks. Compact Design The Safety • J is designed to have the smallest footprint of any Class “J” block on the market, 10% smaller than our closest competitor. This saves valuable panel space. Shown as actual size Part Numbers JT60030: 600V, 30A Class J fuseholder JTN60030: 600V, 30A Class J fuseholder w/indication JT60060: 600V, 60A Class J fuseholder JTN60060: 600V, 60A Class J fuseholder w/indication Touch Safe Safety • J meets IP-20 - IEC 529 standard for touch safety. This also means compliance with the National Fire Protection Assoc. Standard 70E for employee safety. Dual Port Design (30A) This new wire management feature allows daisy-chaining to reduce components and save mounting time, where multiple circuits are connected to a single branch circuit. Safety • J offers Benefits 6. Removable Fuse Carrier: Added Safety while replacing the fuse. The fuse is replaced while removed from the circuit. 7. Probe Holes in Carrier: Easy access to fuse for testing purposes. 8. Internal DIN Rail Release Latch: Easily removed from rail with screwdriver. 9. Reinforced Fuse Clips– Standard: Repeatable low resistance performance. 10. Built-in Labeling System: Makes circuit marking a snap. Shown as actual size 11. Wire Ready: Saves time as terminals are ready to accept wires. 12. Open Fuse Indication available: Fast response to identifying open fuses.* *Load path and voltage source are required for indication. Contact Applications Engineering if you have questions at (314) 527-1270. Easy Installation Mount the Safety • J directly to the panel or snap it onto a 35mm DIN rail w/no special adapters. This provides maximum flexibility in panel assembly. One Piece Interlocking Need to reduce inventory? The Safety • J allows you to lock multiple blocks together. No need to stock numerous part numbers or additional accessories. Removable Fuse Carrier Remove and install the fuse away from the circuit while maintaining Touch Safe requirements at the base unit. Added protection from accidental contact with live parts. Safety • J provides superior protection Why use Safety • J? NEC 110-9 The National Electrical Code requires that a device, used to open an electrical circuit under a short circuit condition, have an interrupting rating sufficient for the current available at the point of installation. Bussmann’s LPJ Class “J” fuses have an unsurpassed interrupting rating of 300 kA. There is little reason to worry about meeting this safety requirement again. NEC 110-10 The National Electrical Code also requires protection of electrical components from damage caused by excess currents. Bussmann’s Class “J” fuse provides excellent current limitation, reducing fault currents to a fraction of their original value. NFPA - 70E The NFPA 70E “Electrical Safety Requirements for Employee Workspaces” is designed to protect employees. The standard states that when working near an energized electrical system (50V and over), employees must be protected “against contact with any part of the body or indirectly through some other conductive object.” Bussmann’s Safety “J” fuse blocks guard against accidental contact with live parts. Available in indicating and non-indicating versions. Designer’s Technical Corner (For more information, please refer to Bussmann’s Electrical Protection Handbook–Bulletin SPD.96) IEC 947-4-1* IEC 947-4-1 offers two (2) standards for protecting motor starters. Type “1” protection is similar to UL 508, which allows equipment to be destroyed under certain overcurrent parameters. Type “2” provides for a “NO DAMAGE” protection. Properly sized Class “J” fuses offer Type “2” protection when coordinated with contactor. IP20 The IEC Standard 529 establishes a system for classifying the degrees of protection provided by enclosures of electrical equipment. The standard was originally developed to test enclosures for protection of persons against accidental contact with live electrical components and the ingress of solid foreign objects. Other interpretations include the components inside of the enclosure when voltage is present and a maintenance person is working near the equipment.
