High surge capability translates to real budget protection. SPD100240S2A provides 100 kA per phase surge protection with a 200 kAIC short-circuit rating for 120/240 V split-phase systems. This means transient events are clamped quickly, reducing insulation stress on motors, drives, and PLCs. The result is lower repair costs and less downtime in manufacturing lines that rely on sensitive electronics. EMI/RFI filtering up to 50 dB from 10 kHz to 100 MHz improves signal integrity for drives, controllers, and HMIs, enhancing equipment uptime and reducing nuisance resets. Audible alarm with a silence button and a surge counter with a rest button enable proactive maintenance and remote signaling via a Form C relay contact, helping facilities integrate protection data with BMS or SCADA systems. Internal mounting and compact dimensions simplify installation in crowded enclosures, while compatibility with Direct bus mounted panelboards PRL1a, PRL2a, PRL3a, and PRL3e reduces wiring and labor costs. Operating across 50/60 Hz and rated for -40 to 50 °C environments, this unit supports diverse industrial applications with robust protection and predictable lifecycle costs.

FAQs
SPD100240S2A is designed for internal mounting with direct bus mounted panelboards, simplifying wiring and speeding up commissioning. Its compact 9.5 in length, 5.4 in width, and 3.5 lb weight help in confined enclosures. Ensure adequate space for service access, verify 120/240 V split-phase supply, and confirm IP20 protection meets your enclosure rating requirements.
The 100 kA per phase rating provides high-energy transient clamping, reducing insulation stress on critical components like motors and drives. Combined with a 200 kAIC short-circuit rating and UL 1449 listed status, this lowers the risk of surge-induced failures and unplanned downtime, improving overall equipment availability and maintenance intervals.
Yes. The unit is rated for -40 to 50 °C and IP20 protection, making it resilient in demanding environments. EMI/RFI filtering up to 50 dB helps maintain control signal integrity for drives and PLCs, while audible and remote signaling features support quick fault diagnosis and action planning during power disturbances.
SPD100240S2A is UL 1449 Listed, indicating compliance with recognized surge protection safety standards. IP20 protection provides enclosure-level ingress protection. While CE certification is not listed in the provided data, the UL listing and IP rating offer essential regulatory alignment for many industrial facilities seeking safe and reliable surge protection.
Key maintenance benefits include an audible alarm with a silence button and a surge counter with a rest button for easy monitoring of surge events. A Form C relay contact enables remote signaling to a plant BMS/SCADA. EMI/RFI filtering improves uptime by reducing noise-induced faults, while the 15-year warranty supports long-term budgeting and lifecycle planning.
