Siemens Centred Tag Fuse For Use With Power Semiconductors, aR Operating Class, HRC Type - SITOR Series - 3NE8021-1 Choose this centred tag fuse from Siemens to protect your industrial devices from the risk of overcurrents. When excess current flows through the unit, an internal metal filament melts and the circuit is broken, preventing damage to downstream equipment. An operating class rating of aR means this is a very fast-acting fuse. It's a practical option for providing effective breaking protection to sensitive equipment such as power semiconductors, UPS systems and motor starters. A varying load factor of 0.95 indicates consistent power usage, so you get reliable results with predictable energy consumption. Features & Benefits • Wide operating temperature range of -20°C to +50°C means it's suitable for use in harsh environments
• Standard fuse size of NH00 ensures wide compatibility
• High rupture capacity fuse, so is maintenance-free and won't deteriorate with age How easy is it to remove this fuse? To ensure your safety, it's important to avoid contact with any live wires. You should always remove an NH fuse such as this one with an appropriate extraction tool, sometimes known as a puller (396-285).
