60 A protection with fusible with neutral provides fast, predictable fault clearing for motor circuits. The two-pole, three-wire configuration simplifies wiring and safeguards both line and neutral paths. In practice, this translates to reduced arc-flash exposure and cleaner coordination with downstream motor starters in conveyors and pumps. HP rating is listed as 3, 7.5 hp/10, 15 hp/10 hp for 1-phase and 3-phase operation with standard fuse and time-delay at 250 Vdc. This allows engineers to size the switch for mixed loads without over-protection, improving energy efficiency and reducing nuisance trips. Enclosure is a NEMA 1 painted steel housing with a windowed blade, enabling quick visual status checks and dependable indoor protection. The rugged finish withstands daily factory conditions, helping maintenance teams identify switch state during shift changes. UL Listed certification ensures safety compliance and audit readiness, while the enclosure design and Class H fuse provision support fault-clearing reliability. When paired with broader protection schemes, this switch helps reduce downtime and extend motor life. Dimensions and installation convenience: 16.5 in depth, 9.12 in width, 8.31 in height, and approx. 20 lb weight. A compact footprint and familiar form factor ease retrofits into existing HDSS installations or panel upgrades, with straightforward wiring and mounting.
