Most devices will recover within 24 hours time. It should be noted that there is no quality defect nor change in protection levels during the temporary change in DCBD. • Sparkover limits after life ±20 % (-25 %, +30 % for Model 2035-09, 2035-60), IR >108. • At delivery AQL 0.65 Level II, DIN ISO 2859. 1 2 Network applied. Tube may exceed ±20 % but will continue to protect without venting. *RoHS Directive 2002/95/EC Jan 27, 2003 including Annex. Specifications are subject to change without notice.
