Surge Protective Devices

SPDN-D Series

UL Type 1

REACH

Description

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 & Beneﬁts

FEATURES

BENEFITS

More direct modes of protection (L-N, N-G) in a

smaller package

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

Capability to clamp and withstand high-energy

transients

Provides more high-transient voltage protection in a compact, multi-

layered structure

Stacked Metal Oxide Varistor (MOV) design

Simplifies maintenance—without impacting the other parts of the

electrical system—by turning breaker off during upkeep

Installs on the line or load side of the circuit breaker

Thermally protected MOV

External LED indicator

Compact footprint

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
