Information About SPD250480Y3C
The SPD250480Y3C is part of Eaton’s SPD Series surge protection product line engineered to protect critical electrical systems from lightning strikes, switching surges, and transient voltage events. Designed for three-phase 277/480V wye systems, it provides comprehensive protection across multiple modes including line-to-neutral, line-to-ground, neutral-to-ground, and line-to-line. The unit is commonly installed in electrical distribution equipment such as switchboards, panelboards, and busway systems where sensitive equipment requires consistent power quality. With integrated monitoring features and surge counting capability, the device helps maintain system reliability while providing diagnostic information about surge events.
Key Features:
- High Surge Current Capacity: Provides up to 250 kA surge current protection per phase for high-energy transient suppression.
- 277/480V Wye System Compatibility: Designed for three-phase, four-wire systems with ground.
- Multi-Mode Protection: Protects electrical circuits in L-N, L-G, N-G, and L-L protection modes.
- Integrated Surge Counter: Tracks surge events for system monitoring and maintenance planning.
- 200 kA Short Circuit Rating: Ensures safe operation in high fault current environments.
- EMI/RFI Noise Filtering: Reduces electrical noise with up to 50 dB attenuation from 10 kHz to 100 MHz.
- Internal Integrated Mounting: Simplifies installation within switchboards, busways, and panelboards.
- Audible Alarm and Relay Contact: Provides fault indication and remote monitoring capability.
The SPD250480Y3C delivers the reliability and precision required for advanced surge protection in commercial and industrial electrical distribution systems.
