FAQs
The SPM400220Y1R is a single-module SPD designed for straightforward integration into standard electrical panels. Its 127/220 V Wye configuration supports common industrial power systems, and it can be mounted within NEMA 4 enclosures. For retrofit projects, confirm busbar spacing and mounting clearances, and verify that the internal circuit breaker can coordinate with your protection scheme to ensure proper isolation during faults.
This device provides 400 kA per phase protection, which absorbs high-energy transients that would otherwise reach sensitive equipment like drives and PLCs. This capability reduces the likelihood of insulation damage, data corruption, and unexpected downtime. In practice, you’ll see improved uptime and longer service life for motor control centers, automation controllers, and other critical loads in demanding manufacturing environments.
Yes. The unit uses a NEMA 4 enclosure designed for harsh industrial environments, including moisture and dust exposure. With an internal circuit breaker, it also provides safe fault isolation. For outdoor installations, ensure proper sealing to panel openings and confirm ingress protection aligns with site conditions while maintaining accessibility for maintenance checks.
The device is UL 1449 and UL 1283 certified, with CSA Electrical Notice NO. 516 Edition 1 and CSA Std. C22.2 No. 8-M1986 listings. These certifications validate electrical safety, performance under surge conditions, and compliance with North American electrical standards—critical for audits, customer requirements, and procurement specifications in regulated industries.
The 15-year warranty (20 years with registration) helps reduce lifecycle costs by transferring much of the ownership risk to the manufacturer. Maintenance requirements are typically minimal beyond periodic visual inspections and confirmation of electrical connections. The device’s protective benefits translate to lower replacement costs for protected loads, fewer unplanned shutdowns, and improved overall equipment reliability in production environments.
