• UL Recognized component, UL File E153537
• DC Breakdown and Impulse Sparkover voltage are specified line to ground. Line to Line values are typically 1.8 to 2 times the stated line to ground values. (1) In ionized mode. (4) Total current rating through center electrode; half value each line to center electrode. (2) IR after life >108 Ω. (5) DC Sparkover may exceed ±25 % after discharge, but will continue to protect without venting. (3) At delivery AQL 0.65 Level II, DIN ISO 2859.
