SRF SERIES combines rugged Triggered Spark Gap technology with effective true L-C filtering and Transient Discriminating (TD) Technology to help create the ultimate in effective and reliable AC surge protection.

SRF reduces let-through voltages and rate-of-voltage rise (dv/dt) and helps provide optimum protection for electronic equipment.

FEATURES

  • High-performance protection incorporating Spark Gap and Transient Discriminating (TD) technologies
  • High surge rating ideal for exposed critical service entrance applications
  • Reduces let-through voltages and rate-of-voltage rise (dv/dt) and helps provide optimum protection for electronic equipment
  • Extreme reliability and simplified design with direct connection from input to output
  • Comprehensive front panel status and internal diagnostic LEDs
