New SPDN Devices Provide Equipment Protection from Transient Overvoltage Events Lasting Micro-seconds

The SPDN surge protection devices include more direct modes of protection such as line to neutral, line to ground, and neutral to ground depending on product selection. With more direct modes of protection in a compact footprint, the SPDN optimizes space and delivers cost efficiencies enhancing panel design flexibility.

The SPDN series (SPDN-A, SPDN-B, SPDN-C and SPDN-D) product features include:

More direct modes of protection in a smaller package, increasing protection and design flexibility
UL 1283 filtering helps mitigate effects on power supplies by decreasing zero crossings during ringing transients to prevent interference on performance or unsafe conditions (SPDN-A only)
Capability to clamp and withstand high-energy transients ensures low-residual voltage during high-energy events and higher nominal discharge current to prevent disruption, downtime and degradation or damage to equipment
Stacked Metal Oxide Varistor (MOV) design provides more high-transient voltage protection in a compact, multi-layered structure
Installation on the line or load side of the circuit breaker to simplify maintenance by turning breaker off during upkeep (SPDN-A installs on the load side only)
Thermally protected MOV eliminates catastrophic failure
External LED indicator quickly identifies service requirements to avoid loss of protection
Compact footprint offers easy retrofit in existing applications where space is limited

ESR Fuses Offer a Wider Range of Protection for Battery Racks

The Littelfuse Energy Storage Rack (ESR) series of fuses are designed specifically to protect battery racks from a range of fault currents to help prevent equipment damage or expensive system failures. The 1500 V dc high-speed square body fuse is extremely fast-acting to respond quickly to safeguard the battery module. Available in NH 1XL and 3XL sizes and a variety of amperages.

Littelfuse Launches Its Class J Fuse Disconnect Switch to Simplify Operation and Protection

The compact Class J Fuse Disconnect Switch combines a switch and multiple fuses into a single product, offering a simpler way to manually open and close a circuit while safeguarding against overcurrent and short circuits while saving space.

Littelfuse Launches Its Most Compact Arc-Flash Relay for Tight Spaces

The AF0025 Series is a cost-effective arc-flash protection solution for OEM applications. With a depth of only 1.82” (46.23 mm), this compact relay significantly reduces arc-fault damage in AC and DC compartments by detecting the light from an arc-flash and rapidly providing a trip signal.

How to Properly Protect a BESS Power Circuit from Overcurrents

A battery energy storage system requires proper circuit protection. Overcurrents not only frequently damage systems, but are also the culprit of downtime, which is detrimental to a company’s bottom line. Fuses are a great way to protect a system simply and cost-effectively. Learn how to properly protect a BESS power circuit from overcurrents with this application guide.

Voltec LED Prefab Temporary Area Lights

Voltec's new line of Prefab temporary area lights are the most customizable option when it comes to temporary lighting. These lights have a custom wiring terminal block with two 1/2 inch threaded knockouts for any 1/2 fitting allowing the user to wire the light to meet any job requirement.

Free Safety Webinar: Why GFCIs with “Ground Check” are the Future of Electrical Safety

New technology blends a ground-fault circuit interrupter’s (GFCI’s) fast reaction time with proactive ground monitoring technology, which ensures a safe and reliable ground-fault path. This new pre-emptive approach originated from the special-purpose GFCI (SPGFCI) standard, but it is time to apply it to Class-A GFCIs.
