The PGDTs\u2019 follow current-limiting capabilities ensure that the SPD can operate in any network without risk of nuisance tripping during SPD operation. Surge performance of PGDT technology allows the SPD to be narrower (1TE per pole instead of 2TE per pole) and lower \u2013 only 70 mm from DIN rail, further reducing space requirements and enabling high-performance SPDs to be installed even in the smallest applications.<\/p>\n<p style=\"text-align: left;\"><strong>Features and Advantages:<\/strong><img loading=\"lazy\" decoding=\"async\"
