FAQs
The SPM320240S1S is a two-module SPD designed for 120/240 V split-phase panels and comes in a NEMA 4 enclosure with an internal circuit breaker. For best results, mount in the main distribution or branch panel adjacent to protected loads, ensure proper conductor routing, and connect per Eaton wiring diagrams to minimize impedance and maximize surge resilience.
This unit carries UL 1449 and UL 1283 listings, CSA certification, and RoHS compliance. These approvals confirm endurance against surges, compatibility with industrial electrical standards, and reduced hazardous materials in manufacturing environments. The certifications support procurement mandates and help ensure regulatory compliance across facilities.
The device is rated for 120/240 V, uses two modules, and delivers up to 320 kA per phase surge protection. It features a standard surge counter, and is enclosed in a NEMA 4 housing with an internal circuit breaker for safe operation and easy maintenance in varied environments.
By effectively suppressing transient energy, the SPM320240S1S helps prevent premature equipment failures, reducing downtime and repair costs. The built-in surge counter enables data-driven maintenance planning, while the long warranty provides financial protection and predictable budgeting for asset protection.
Yes. The SPM320240S1S uses a NEMA 4 enclosure, which is designed to withstand wet and dirty environments. For outdoor installations, ensure proper mounting clearance and follow installation guidelines to maintain protection performance and accessibility for servicing the internal circuit breaker.
