SPD100K-277 AC Surge Protector

For more details call:


A frequent cause of electrical/electronic equipment failure is AC power line surges.  This is especially true in the case of sensitive electronic equipment such as LED lighting systems, CATV systems, traffic controllers, data processing equipment, telecommunication systems, etc.  These power line surges can vary from noise-like transients to spectacular lightning induced surges.  Therefore, the effect on costly equipment can vary from a slow degradation of performance to catastrophic failure. 

The SPD100K solid state arrester has been designed to effectively dissipate high energy surges up to 100kA(8x20us). High energy induced surges usually originate on the primary side of the power transformer and are consequently transferred to the secondary. The SPD100K design incorporates UL approved, high energy, thermally fused and protected 50kA large block MOVs. The powerful, parallel-connected SPD100K is available in a variety of electrical configurations. The unit also offers exterior panel LED status indication. The SPD100K comes with a standard 1 year, fully transferable warranty with extended warranty available.
