Description
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.
Features:
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
Benefits:
Increases protection and design flexibility
Ensures low-residual voltage during high-energy surge events and higher nominal discharge current to prevent disruption, downtime, and degradation or 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
Applications:
Construction
Food and Beverage
HVAC/R
Light Industrial
Oil and Gas
Water/Wastewater
