Bussmann LPS-R-225 Dual Element Time Delay Fuse

Bussmann Low-Peak LPS-R-225 is a dual-element, time-delay fuse rated at 225 A, built to protect power circuits while tolerating brief inrush currents. As part of the Low-Peak LPS-R family, this fuse uses two elements to deliver current-limiting, time-delay protection with blade-end terminals and non-indicating construction for compact panel layouts. The LPS-R-225 is listed as Class RK1 in Bussmann’s RK-series lineup and is designed for 600 VAC / 300 VDC operation, with an interrupting rating up to 300 kAIC at 600 VAC and 100 kAIC at 300 VDC. This dual-element device is intended for circuits where short surges must be allowed, such as during startup or transient overloads, while its time-delay characteristics help prevent nuisance blows on startup impulses and safeguard conductors and downstream equipment during fault conditions. The current-limiting feature further confines fault energy, reducing the risk of damage to wiring and components in electrical panels and power-distribution networks.
