Littelfuse SB5000 Shock Blocks will Rock your World

ByPeter Mau


Standard Electric and Littelfuse are proud to announce the release of the SB5000 Series, the newest Industrial Shock Blocks (ISB) to date. This series includes multiple options: Class A, C, D, and EGFPD. It offers complete flexibility, due to the ability of it being user programmable, and increases efficiency while offering a massive boost in safety due to reduced false positives and unnecessary trips.

Features & Benefits:

  • UL 943 inverse time trip curve
  • Minimum trip time < 20 msec
  • Flexible configuration
  • Conformal coating
  • Auxiliary contact
  • Automatic self-test
  • Two-stage ground monitor with Zener termination that meets:
    • UL 943C, CSA M421, NEC 590.6(B)

With the UL 943, you can protect people even more while also decreasing the number of trips set off. Additionally, the minimum trip time reduces the danger of ventricular fibrillation for a leakage current of 250 mA and above. But wait! There’s more! These shock blocks have a conformal coating (protecting against corrosion and moisture), an auxiliary contact that can alert your SCADA system, AND has an automatic self-test that tests itself constantly in case there is an internal failure.

Not much left to say for these Shock Blocks, except that they seriously ROCK!
