SPDN-B Series Surge Protective Devices
■Surge protective devices (SPDs) provide equipment protection from transient overvoltage events lasting micro-seconds. 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, L-G, 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, multilayered 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
