FAQs
Install the SPD within the designated direct bus mounted panelboard section (PRL1a, 2a, 3a, 3e) using the internal mounting features. Ensure correct phase connection for 240V delta systems, verify MCOV ratings (150 L-N, L-G, N-G; 300 L-L), and connect the Form C relay to your control/alarm system. Properly observe enclosure clearance and ambient temperature limits (-40 to 50 °C) for reliable operation.
The device provides a 100 kA per phase surge current rating with a 200 kAIC interrupt rating, plus 150 L-N, 150 L-G, 150 N-G, and 300 MCOV. It operates on 50/60 Hz and is UL 1449 Listed, ensuring robust protection for sensitive loads in 240V delta configurations.
Yes. The 240V delta configuration with 4W+G foundational rating and the specified L-N/L-G/N-G voltages are designed for challenging delta networks, including high-leg delta applications. The device’s internal mounting and compatibility with Direct bus mounted panelboards simplify integration in such systems.
SPD100240H2A carries UL 1449 Listed certification and is designed to meet or exceed the safety and performance expectations referenced by IBC 2006, CBC 2007, and UBC Zone 4. These certifications support compliance reporting and fit typical industrial safety programs.
The built-in surge counter with rest button enables proactive maintenance scheduling by signaling events and enabling timely inspections. EMI/RFI filtering reduces noise-induced downtime, while the 15-year warranty lowers lifecycle costs and protects capital investments by extending equipment life and minimizing unplanned outages.
