FAQs
SPD100480D1J is designed for motor control centers with 480 V delta service. Ensure mounting within the MCC enclosure, provide proper panel grounding, and confirm integration with Form C signaling and the audible alarm. Confirm compatibility with local codes and the device’s internal mounting requirements to streamline retrofit projects.
Key specs include 100 kA per phase surge current, 200 kAIC short-circuit rating, 640 V-G and 640 V-L-L MCOV, and a 50/60 Hz frequency rating. The device is rated for 480 V delta systems and offers EMI/RFI filtering up to 50 dB, supporting reliable operation in demanding industrial environments.
SPD100480D1J carries UL 1449 and UL Listed certifications. These indicate compliance with established surge protection standards, ensuring safety, reliability, and performance in electrical protection installations within industrial facilities and motor control centers.
By limiting transient events with a high surge current rating, the device reduces motor insulation stress and downtime. The audible alarm, surge counter, and Form C relay enable faster fault detection and proactive maintenance, while a 15-year warranty lowers lifecycle costs for aging MCC infrastructure.
Plan for internal integrated mounting, verify 480 V delta wiring, and confirm MCOV compatibility with 640 L-G / 640 L-L. Ensure proper derating if ambient temperatures approach the -40 to 50 °C range, and integrate with existing MCC alarm and signaling systems to maximize protective coverage.
