FAQs
The SPD100480D2A is designed for internal integrated mounting and aligns with Direct bus mounted panel boards PRL1a, 2a, 3a, and 3e. Begin by ensuring voltage rating matches 480V delta, confirm mounting clearance, and connect per the provided wiring diagram. The compact 9.5 x 5.4 x 3.45 inch footprint and 3.5 lb weight simplify retrofits. After installation, verify the EMI/RFI filter engagement and the integrity of the Form C relay contact for signaling.
SPD100480D2A provides 100 kA per phase surge capacity, 20 kA nominal discharge current, and 200 kA short-circuit rating. It operates at 50/60 Hz with 480 V delta ratings and supports -40 to 50 °C ambient conditions. Expect EMI/RFI attenuation up to 50 dB across 10 kHz to 100 MHz, helping protect sensitive controllers and drives.
Yes. With EMI/RFI filtering delivering up to 50 dB attenuation and a robust 100 kA per phase surge rating, the device mitigates noise and transient energy common in motor-heavy facilities. Its integrated alarm and durable enclosure support reliable operation in environments with vibration, dust, and temperature swings within -40 to 50 °C.
