Eaton SP3-240D Surge Protective Device - 50 kAIC
Part Number: SP3-240D
Quick Summary
The Eaton SP3-240D surge protective device protects three-phase electrical systems from transient surges in industrial automation environments. Downtime caused by lightning and switching transients can derail projects and inflate maintenance costs. While SP3 products align with industry standards such as CE compliance and IP-rated enclosures, verify your regional requirements. The design supports rapid panel installation and predictable protection, delivering increased uptime and reduced lifecycle costs for automation panels. This SP3-240D variant delivers 50 kAIC surge current capability, a compact footprint, and a three-phase delta configuration for panel protection in motor drives, conveyors, and process controls. In practice, that translates to smaller control panels, easier wiring, and a measurable reduction in nuisance trips.

Feature: The SP3-240D provides a 50 kAIC surge current rating, delivering high-energy transient protection. Business Impact: This level of protection reduces insulation stress, lowers the probability of downstream device trips, and minimizes unplanned downtime in critical automation lines. Application: Deploy in three-phase delta systems where motor drives, PLCs, and process controllers demand robust transient protection at the source. Feature: The compact form factor — 2.5 in depth, 4.8 in height, 2.9 in width — combined with a 1.25 lb weight, enables easy panel integration. Business Impact: The smaller footprint saves cabinet space, reduces wiring complexity, and speeds on-site installation without sacrificing protection. Application: Suitable for tight control cabinets and modular industrial panels where space is at a premium and serviceability matters. Feature: Eaton's SP3 series leverages Innovative Technology Protector architecture for fast response and reliable clamping. Business Impact: Enhanced reliability translates to fewer nuisance trips, better data integrity, and longer life for connected equipment in harsh environments. Application: Automation panels, machine controls, and process instrumentation where consistent surge suppression is mission-critical. Feature: Three-phase protection with 240 delta configuration targets three-phase loads and provides balanced shielding across lines. Business Impact: Protects motors, drives, and sensors from transient energy, improving uptime and reducing repair costs. Application: Ideal for motor control centers, packaging lines, conveyors, and other heavy-industrial processes where phase-to-phase surges are a concern. Feature: Easy installation and compatibility with standard Eaton SP3 devices and common enclosure practices. Business Impact: Streamlines panel upgrades and maintenance planning, enabling predictable lead times and consistent performance. Application: Suitable for retrofit and new builds in automation panels, OEM equipment, and facility electrical rooms that require proven three-phase surge protection.

FAQs
Install SP3-240D in a suitable three-phase panel by ensuring it is mounted in a compliant enclosure with proper spacing for heat dissipation. Connect the three line terminals to the L1, L2, and L3 phases and bond the protective leads per the Eaton SP3 installation guide. Verify torque specs and follow local electrical codes for safe operation and optimal protection.
A 50 kAIC surge rating indicates the device can safely absorb and clamp high-energy transient surges up to 50 kiloamps at the point of protection. This reduces the likelihood of downstream equipment insulation damage, minimizes nuisance trips, and preserves uptime for motors, drives, PLCs, and automation panels in demanding industrial environments.
SP3-240D is part of Eaton’s SP3 surge protection family and is designed for three-phase delta configurations. While the provided data confirms its 240 delta configuration, always verify exact voltage ratings and compatibility with your panel’s supply (voltage level, phase arrangement, and enclosure standards) against Eaton’s official specifications before retrofit or new installs.
The provided data lists no specific certifications beyond the implied industry-standard performance. For regulatory assurance, confirm with Eaton documentation whether SP3-240D carries CE marking, IP-rated enclosure, or other regional certifications relevant to your installation. Always verify certifications for your location and project requirements.
SP3-240D enhances equipment protection against transients, reducing unexpected downtime and repair costs in automation lines. Its compact footprint simplifies panel design and installation, enabling faster deployments and consistent protection across multiple machines. Over the lifecycle, this translates to improved uptime, lower maintenance expenses, and stronger return on investment for OEMs and end users.
