The SPD100480D1A features integrated mounting and compatibility with Direct bus mounted panel boards PRL1a, 2a, 3a, and 3e, enabling quicker installations and a cleaner panel footprint. This directly translates to reduced labor costs and fewer components in the field, which minimizes commissioning time and potential errors during setup. The device delivers robust protection with a 100 kA per phase surge rating and a 200 kAIC short-circuit rating, increasing protection margins for critical loads and downstream equipment in demanding industrial environments. With a nominal discharge current of 20 kA and a 480 V delta rating, it provides dependable performance across standard plant loads and motor-driven applications while maintaining 50/60 Hz compatibility. EMI/RFI filtration up to 50 dB from 10 kHz to 100 MHz reduces electrical noise, improving PLC and drive performance and extending life of sensitive electronics. Audible alarm with a silence button and a Form C relay contact give clear status signaling and remote fault indication for maintenance planning. The surge counter with a rest button supports proactive maintenance by documenting event history, while the 15-year warranty reinforces long-term ROI. This combination of protection, visibility, and ease of installation is particularly beneficial for manufacturers and facilities relying on uninterrupted 3-phase power.
