BUSSMANN LPS-RK-3SP Fuse

The BUSSMANN LPS-RK-3SP is a Low-Peak, Class RK1 fuse in the Bussmann LPS-RK family, designed for time-delay, dual-element protection of general-purpose circuits where inrush is a concern. It is a 3 A fuse rated for up to 600 V AC and 300 V DC, with a short-circuit interrupting rating of 300 kA at 600 VAC and 100 kA at 300 V DC, and it is non-indicating. The dual-element construction provides current limiting and time-delay operation, and the Low-Peak design supports selective coordination with other RK1 fuses to withstand inrush events without unnecessary nuisance trips. This model meets UL 248-12 performance requirements for Class RK1 fuses and is commonly used in protection schemes where RK1 devices are preferred to manage high inrush loads while protecting downstream circuitry.
