FAQs
The LPS-RK-80SP-TP is designed for large distribution switchboards and motor control centers operating at up to 600 V and 300 Vdc. It supports RK1-class protection with time-delay, current-limiting characteristics and electrically isolated end caps for safe, straightforward installation in standard MCC enclosures and protection panels.
Key ratings include 80 A current rating, 600 V AC and 300 V DC voltage ratings, and interrupt ratings of 100 kAIC for Vdc and 300 kAIC at 600 Vac. The fuse combines time-delay operation with current-limiting protection to balance normal inrush with rapid fault isolation, reducing energy through faults.
Yes, it's intended for large distribution switchboards and MCCs. Install with electrically isolated end caps for safe maintenance, and ensure mounting accommodates its 7.88 in length and 1.11 in cross-section. Tin-plated contacts improve durability, and the RoHS-compliant design supports regulatory alignment in modern panel builds.
The product is RoHS compliant and classified as RK1. While specific CE or SIL certifications are not listed in the provided data, RoHS compliance and the RK1 classification support regulatory readiness and standardized protection in industrial panels.
The tin-plated construction resists corrosion, reducing contact wear over time. Time-delay, current-limiting protection minimizes nuisance trips while preserving drive start-up performance, contributing to higher uptime and lower maintenance costs in MCCs and switchgear-heavy installations.
