FAQs
Install the LPS-RK-2SP with ferrule-end terminals into compatible RK1 fuse holders or panels designed for Bussmann series devices. Ensure correct amperage (2 A) and voltage ratings (600 Vac / 300 Vdc) are used for the circuit. Verify secure connection, align with existing wiring, and replace only with the same LK1-class, time-delay, current-limiting fuse to maintain protection integrity.
The LPS-RK-2SP provides an interrupt rating of 300 kAIC at 600 Vac and 100 kAIC at 300 Vdc, with a voltage rating of 600 Vac / 300 Vdc. It is rated at 2 A, offering reliable short-circuit protection for industrial control circuits while tolerating normal inrush in motor applications.
Yes. The time-delay, dual-element design of the LPS-RK-2SP is well-suited for motor starting protection, allowing inrush currents without tripping while still providing rapid fault interruption during actual faults. Its RK1 class and ferrule-end connections simplify panel integration and replacement in motor control applications.
The LPS-RK-2SP is CE Marked, aligning with European safety and environmental requirements. This certification supports compliance in many industrial environments, while its Class RK1 designation provides recognized fuse protection standards within Bussmann’s RK1 family.
The fuse reduces nuisance trips from inrush, protecting downstream components and extending equipment life, which lowers maintenance costs and unplanned downtime. Its standardized ferrule-end design and robust interruption ratings also shorten maintenance windows and improve overall reliability in multi-site industrial deployments.
