FAQs
SPD100240S1L is designed for 120/240 V single‑phase systems and supports external sidemount installations in indoor electrical distribution panels. It fits within NEMA 1 enclosures, enabling retrofit in existing gear while maintaining a compact footprint.
The 100 kAIC interrupt rating indicates the device can safely interrupt very high surge currents without failure. This translates to stronger transient protection for connected loads, reduced risk of equipment damage, and greater protection margins in environments with frequent or severe electrical disturbances.
No. SPD100240S1L uses a NEMA 1 enclosure designed for indoor installations. For outdoor or harsher environments you would need a variant with appropriate ingress protection or an enclosure rated for the intended conditions, plus appropriate weatherproofing and mounting considerations.
UL 1449 certification confirms compliance with recognized surge protection standards, supporting safety and performance claims. This certification, together with Eaton’s 15‑year warranty, provides confidence in long‑term protection and lower lifecycle risk for mission‑critical systems.
SPD100240S1L offers a maintenance‑light profile with no moving parts, backed by a 15‑year warranty. Plan for periodic inspection during routine panel maintenance, verify mounting integrity, and replace if mounting or enclosure damage is observed to maintain optimal protection levels.
