FAQs
The SPM120240D1R is designed for 240 Delta (3W+G) systems and comes in a compact NEMA 4 enclosure with an internal circuit breaker. When installing, verify panel footprint compatibility, ensure adequate clearance for heat dissipation, and connect per the manufacturer wiring diagram. The internal breaker simplifies isolation during maintenance and minimizes downtime during surge events.
UL 1449 certification confirms performance under transient conditions, while UL 1283 addresses electrical safety and insulation requirements. Together with CSA recognition and RoHS compliance, these certifications reduce supplier risk, streamline your QA approvals, and ensure the SPD meets industry safety standards for panel protectors in industrial environments.
Yes. With a 120 kA per phase rating and 240 Delta (3W+G) configuration, the SPD MAX is well-suited to shield drives, PLCs, sensors, and MCCs from surge events common in manufacturing lines. Its NEMA 4 enclosure and internal breaker support reliable performance in challenging environments, helping maintain line uptime and equipment health.
The SPM120240D1R provides long-term protection with a 15-year warranty (20 years when registered). By preventing surge-induced failures, facilities can reduce unplanned downtime, extend equipment life, and lower maintenance costs. The internal breaker also simplifies servicing, minimizing labor and risk during replacement or testing.
Ensure compatibility with your 240 Delta (3W+G) system, confirm enclosure fit for the panel, and verify certification alignment (UL 1449, UL 1283, CSA, RoHS). Check the space for the 50 lb unit, wiring gauge per diagram, and that the internal circuit breaker is suitable for your maintenance protocol. This reduces retrofit risk and improves long-term protection.
