Surge protective devices (SPDs) provide equipment protection from transient overvoltage events lasting microseconds. By limiting the overvoltage to the equipment during these events, costly damage and downtime can be mitigated. The NEMA-style SPDN series for external panel mount is available for 120 V to 480 V nominal voltage sub-distribution board applications.
- More direct modes of protection (L-N, L-G, N-G) in a smaller package
- UL 1283 EMI/RFI filtering – 50 dB from 10 kHz to 100 MHz
- Capability to clamp and withstand high-energy transients
- Stacked Metal Oxide Varistor (MOV) design
- Installs on the load side of the circuit breaker
- Thermally protected MOV
- External LED indicator
- Compact footprint
- Increases protection and design flexibility
- Helps mitigate effects on power supplies by decreasing zero crossings during ringing transients
- Ensures low-residual voltage and high nominal discharge current during high-energy surges to prevent disruption, downtime. and damage to equipment
- Provides more high-transient voltage protection in a compact, multi-layered structure
- Simplifies maintenance−without impacting the other parts of the electrical system−by turning breaker off during upkeep
- Eliminates catastrophic failure
- Quickly identifies service requirements to avoid loss of protection
- Offers easy retrofit in existing applications where space is limited
