Feature → Business Impact → Application: The SPD100240H2B delivers 100 kA per phase surge current, backed by a 200 kAIC short-circuit rating, which directly reduces the risk of transformer and motor damage during transient events and extends equipment life in critical applications. This translates to lower maintenance costs, fewer unplanned outages, and improved uptime for critical processes in manufacturing, water treatment, and data-center environments. Application-wise, the device targets 240 V delta (4W+G) systems and is designed for use with switchgear that includes a remote display, enabling technicians to monitor protection status from a centralized control room. Compatibility with 50/60 Hz systems ensures broad applicability across global facilities. A 15‑year warranty further mitigates total cost of ownership and supports long-term project ROI. EMI/RFI filtering up to 50 dB from 10 kHz to 100 MHz helps meet regulatory noise limits while preserving system performance. The audible alarm with silence button and built‑in surge counter give operators actionable, real-time protection visibility, reducing nuisance events during commissioning and operation. Internal integrated mounting simplifies installation and reduces enclosure changes, saving time during panel buildouts and retrofits.

FAQs
SPD100240H2B is designed for 240 V delta (4W+G) systems and is specified for use with switchgear that features a remote display. Ensure your panel supports internal integrated mounting and is within 50/60 Hz operation. Check that the unit’s form C relay, audible alarm, and EMI/RFI filtering align with your control room monitoring and noise requirements. The compact footprint (9.5 in x 5.4 in x 3.45 in, ~3.5 lb) helps fit standard enclosures without large installation changes.
Key ratings include 100 kA per phase surge current, 200 kAIC short-circuit rating, nominal discharge current of 20 kA, and operating voltage of 240 V delta (4W+G). It supports 50/60 Hz operation and provides protection for L-N, L-G, N-G paths with an MCOV of 300 V. These specs collectively protect sensitive equipment from transient events and transient-induced outages.
Yes. The SPD100240H2B is rated for 240 V delta (4W+G) systems and accounts for B-phase conditions typical of high-leg delta configurations. This makes it appropriate for areas where the B phase experiences distinctive transients, helping maintain protection across all three phases and ensuring consistent EMI/RFI performance.
The device carries UL 1449 Listed certification, indicating compliance with essential surge protection safety requirements. It also aligns with building-code considerations such as IBC 2006, CBC 2007, and UBC Zone 4, supporting regulatory acceptance for commercial and industrial installations and simplifying code-compliant procurement.
SPD100240H2B includes a 15-year warranty, reducing long-term ownership costs. It features an audible alarm, silence button, and an internal surge counter for ongoing protection visibility. Because it is a passive protective device with integrated mounting, routine maintenance is typically not required beyond periodic visual inspections and confirmation of the remote-display interface during commissioning.
