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, N-G) in a smaller package
- Capability to clamp and withstand high-energy transients
- Stacked Metal Oxide Varistor (MOV) design
- Installs on the line or load side of the circuit breaker
- Thermally protected MOV
- External LED indicator
- Compact footprint
- Increases protection and design flexibility
- Ensures low-residual voltage during high-energy surges and higher nominal discharge current 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
