FAQs
SPD100480Y1J is designed for integration within motor control centers that operate at 277/480 V (4W+G) and support 50/60 Hz. It features an internal integrated mounting approach, compatible dimensions, and a Form C relay for signaling. Ensure adequate space for heat dissipation, proper enclosure clearance, and wiring to the device’s terminals per the manufacturer’s installation guide to maximize performance and reliability.
The device delivers 100 kA per phase surge capability with a 200 kAIC interrupt rating, complemented by a 20 kA nominal discharge current. These ratings absorb transient energy from utility and switching events, preventing overvoltage from propagating to motors and controls, thereby reducing insulation stress and extending equipment life in MCC environments.
Yes. The unit carries UL 1449 Listed certification, indicating compliance with recognized safety standards for surge protection devices. In addition to protection, the design supports safe operation across the typical industrial temperature range (-40 to 50 °C) and aligns with standard MCC applications, contributing to safer installations and easier regulatory audits.
Absolutely. The SPD includes EMI/RFI filtering that provides up to 50 dB of noise attenuation from 10 kHz to 100 MHz. This filtering helps minimize conducted and radiated interference, improving downstream equipment performance, reducing sensitive equipment errors, and supporting compliance with EMC requirements in modern industrial settings.
The device includes a surge counter with a rest button for fault review, an audible alarm with a silence option, and a Form C relay contact for auxiliary signaling. These features enable proactive maintenance, faster fault diagnosis, and straightforward integration with plant monitoring systems, delivering better asset management and reduced unplanned downtime.
