Special features
Basic
Feature → Business Impact → Application: The SPM400240H1V delivers 400 kA per phase protection, reducing the risk of motor drives, PLCs, and control hardware failure during transient events. This translates to measurable downtime reduction, extended equipment life, and lower maintenance costs across automated lines and panels. Application: Use in critical industrial controls and motor control centers to safeguard sensitive loads while keeping protection within the SPD MAX family. Long-tail keywords such as industrial surge protection device, 400 kA per phase SPD, and 240V delta protection are integrated to support technical search queries. Feature → Business Impact → Application: The 240 delta (4W+G) configuration ensures correct wiring and reliable phase balance for four-wire systems, minimizing installation errors and post-install troubleshooting. Application: Ideal for delta-powered panel boards and mixed-control environments where precise surge routing matters. Feature → Business Impact → Application: NEMA 4X enclosure with internal circuit breaker provides rugged outdoor or harsh-indoor protection, reducing weather-related failure risk and simplifying integration into existing panels. Application: Panel builders and integrators can deploy without additional weatherproof enclosures or external breakers. Feature → Business Impact → Application: 15-year warranty (20 years with registration) demonstrates long-term reliability and lowers lifecycle costs, supporting total cost of ownership (TCO) objectives. Application: Procurement teams seeking durable, standards-compliant protection for factory floors and process lines. Feature → Business Impact → Application: RoHS compliance and established certifications (UL 1283, UL 1449, CSA) reduce regulatory risk and ease customer audits. Application: OEMs and end users pursuing rigorous compliance for machinery and control panels.

FAQs
Install the SPM400240H1V in a compatible enclosure, ensuring a proper panel space for the 9.3 in depth, 17.5 in height, and 14.91 in width. Wire per 240V delta (4W+G) guidelines, connect to the bus and ensure the internal circuit breaker is correctly set. The unit is designed for straightforward retrofit into existing panels within the SPD MAX line.
The device provides 400 kA per phase protection, which minimizes the likelihood of insulation damage and equipment failure during high-energy transients. This rating is particularly important for motors, drives, and PLCs in industrial automation where large surges can occur from switching or external grid events.
Yes. The unit features a NEMA 4X enclosure designed to withstand washdown, moisture, and particulate exposure. This makes it suitable for outdoor panels, rugged manufacturing floors, and process environments where environmental protection is essential.
This SPD carries UL 1283 and UL 1449 safety listings and CSA markings, confirming electrical safety and performance. RoHS compliance is also noted, helping with regulatory audits and customer-required environmental standards across machinery and control panels.
The warranty spans 15 years from delivery, with a 20-year extension available when registered. This long-term coverage reduces maintenance costs and replacement risks, contributing to lower total cost of ownership for equipment protected by this device.
