Special features
Standard with surge counter
Two-module configuration delivers 400 kA per phase on a 240 Delta (3W+G) system, providing robust defense against high-energy transients. This high surge capability protects motor drives, contactors, relays, and expensive electronics from damaging peaks, reducing downtime and replacement costs. Ideal for control panels, machine centers, and process equipment where reliability is mission-critical. Surage counter standard feature enables operations teams to monitor event activity, plan maintenance, and verify protection effectiveness over time. With clear surge history, you can optimize part replacement intervals and support regulatory reporting without guessing when a module needs service. NEMA 4 enclosure with an internal circuit breaker delivers rugged, weather-resistant protection and simplifies field wiring. The integrated breaker reduces panel space requirements and provides an extra layer of safety during maintenance, making installation in outdoor or dusty environments straightforward for electrical crews. RoHS compliant and certified to UL 1449, UL 1283, CSA C22.2 No. 8-M1986, the unit meets essential safety and environmental standards. This compatibility means fewer compliance hurdles during audits and a smoother path for cross-site deployments in multi-national facilities. Warranty spans 15 years from delivery, with a 20-year term available when registered on Eaton's site, underscoring long-term value. Coupled with a standard surge counter and durable construction, this SPD reduces lifecycle costs and supports a consistent protection policy across facilities. Designed to fit the Eaton SPD MAX family, the SPM400240D3S enables straightforward scoping and retrofit compatibility across sites, enabling faster deployment and consistent protection strategy.

FAQs
Begin by mounting the SPM400240D3S in a suitable enclosure and confirm NEMA 4 rating. Wire L1, L2, L3 and ground per the Eaton installation guide, then install the internal circuit breaker. Ensure the unit is properly labeled, and activate the built‑in surge counter for ongoing monitoring. Verify clearances and torque specifications during final wiring to prevent overheating or arcing.
The SPM400240D3S delivers 400 kA per phase in a 240 Delta (3W+G) configuration, allowing it to clamp high-energy transients and limit voltages seen by protected equipment. This performance reduces equipment stress on drives, relays, and sensors, minimizing the risk of insulation failure and unwanted downtime during grid spikes or switching events.
This SPD is ideal for industrial control panels, motor control centers, process equipment, and HVAC systems in manufacturing, water treatment, and packaging environments. Its rugged NEMA 4 enclosure and high surge capacity support outdoor or dusty plant floors, providing reliable protection across multi-site deployments.
The unit is RoHS compliant and carries certifications including UL 1449 and UL 1283, with CSA C22.2 No. 8-M1986 listed. These standards confirm electrical safety, performance under transient conditions, and environmental compliance suitable for regulated industrial environments.
The SPD carries a 15-year warranty from delivery, extended to 20 years when registered on Eaton’s site. This long warranty, coupled with a built-in surge counter for proactive maintenance, lowers lifecycle costs by reducing unexpected outages, facilitating predictable maintenance planning, and supporting a consistent protection strategy across facilities.
