Overview

The nVent HBF31284 is a 30A, 1-pole (1P) fuse holder designed for Class J fuse protection in industrial power distribution systems. This fuse holder is part of the nVent HB2 series and is rated for up to 600V AC/DC, making it suitable for high-performance electrical panels, control systems, and machinery. Constructed from durable plastic, the HBF31284 measures 4.65 x 1.42 x 2.76 inches (118.1 x 36.1 x 70.1 mm) and weighs approximately 0.135 kg (0.298 lbs) per unit. It features a compact design optimized for busbar systems and modular installations, with a protection degree of IP20 for basic protection against solid objects. This fuse holder supports Class J fuses up to 30A and is designed for thermal currents (Ith) of 30A at 20°C (68°F). It complies with IEC 60269-2, UL 4248-1, and CSA-C22.2 No. 4248-1 standards, ensuring global compatibility and safety. The rated insulation voltage (Ui) is 690V, and the prospective short-circuit current withstand is 120 kA RMS at 400/500V AC and 100 kA RMS at 690V AC. Connection options include solid and stranded copper cables with cross-sections ranging from 0.75 mm² (18 AWG) to 16 mm² (8 AWG) for solid and 16 mm² (8 AWG) to 25 mm² (6 AWG) for stranded wires, with a tightening torque of 2.5 Nm (22 lb-in). The HBF31284 is ideal for use in power distribution panels, motor control centers, industrial machinery, and renewable energy systems where reliable fuse protection is critical. Its modular design allows for easy integration into existing busbar systems, and the plastic construction ensures resistance to environmental factors while maintaining electrical integrity. The fuse holder can be padlocked open and sealed closed for enhanced operator safety during maintenance, and versions with blown fuse indicator lights are available for immediate fault detection. For engineers and technicians seeking a compact, high-current fuse holder with robust specifications and global compliance, the nVent HBF31284 delivers dependable performance in demanding industrial applications.
