The Bussmann BP/FRN‑R‑30ID is a dual‑element, time‑delay Class RK5 fuse designed for demanding electrical applications requiring superior overload tolerance and short‑circuit protection. This fuse features easyID™ blown‑fuse indication, making troubleshooting faster and more efficient in motor circuits, panelboards, and industrial equipment.

Key Features

• 30 Amp, 250 Volt dual‑element time‑delay fuse for AC power distribution circuits. 
• Time‑delay action allows temporary inrush currents from motors and inductive loads without nuisance blowing (minimum 10 seconds at 500% current). 
• EasyID™ indication strip visibly darkens when the fuse opens, simplifying circuit maintenance. 
• Current‑limiting Class RK5 design provides enhanced short‑circuit protection. 
• Dual‑element construction separates overload and short‑circuit response for optimal equipment protection. 
• Package includes 2 fuse cartridges.
