Standard Electric and Littelfuse have the perfect family of Surge Protection Devices (SPD’s) ready to protect your devices. The SPD's come in two series'; the SPDN and Type 2 SPD. While very similar, they have certain applications that with specific benefits to your components.
Littelfuse Type 2 Surge Protection Devices (SPD2s) for branch circuits safeguard components from transient overvoltage or surges by limiting the fault current to a load or the unit being protected. Surges may be caused by an indirect lightning strike but, the majority—sixty to eighty percent*—are caused by equipment being turned on or off within a facility. These surges damage components which cost money to repair or replace as well creating unplanned downtime resulting in unfulfilled orders, missed deadlines, unreliable systems and/or dangerous situations.
The DIN-rail mounted SPDs are available in a wide range of operating voltages and include solar applications. They are Ideal for:
- Power Distribution
- HVAC or Medical Equipment
- Industrial Controls
- Electrical Loads
- Computers and Communications
SPD2 Features:
- Capability to clamp and withstand high-energy transients.
- UL and VDE-IEC compliant in single part number
- Interlocking tab mechanism
- SPD type and voltage-coded plug-in module
- Compact footprint
- Visual life indicator
- Pluggable modules
- Thermal protection
- IP20 protection rating
As you may know, 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. They are ideal for:
- Construction
- Oil and Gas
- Food and Beverage
- Water/Wastewater
- Light Industrial
- HVAC/R
SPDN Features:
- More direct modes of protection in a smaller package
- UL 1283 EMI/RFI filtering – 50 dB from 10 kHz to 100 MHz (SPDN-A only)
- 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 (SPDN-B, C, D) Installs on the load side of the circuit breaker (SPDN-A only)
- Thermally protected MOV
- Externally LED indicator
- Compact footprint
Surges can happen to any machine at any time. Not being prepared can mean major delays and issues in the event of an unexpected surge. Prepare and be ready with Littelfuse Surge Protective Devices.
