The products ensure safe thermal and fault-current disconnection on networks with prospective currents as low as 300A and as high as 100,000A. On networks with high prospective short circuit currents, SPDs with integrated fuses provide enhanced safety and fault-current protection due to the coordinated tripping characteristics of the thermal disconnect and the integrated fuse.<\/p>\n<p><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/T1SF-product-video-OR.mp4\" target=\"_blank\" rel=\"noopener\">ProTec T1SF video introduction<\/a><\/p>\n<p><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2025\/11\/EN_G29-01-629-T1SF_T2F_SPD-with-integrated-fuse_leaflet_RevB.pdf\">Lightning and Overvoltage Protection with Integrated Fuse &#8211; leaflet<\/a><\/p>\n<p>&nbsp;<\/p>\n<table style=\"height: 216px; width: 75.9012%; border-collapse: collapse;\">\n<tbody>\n<tr style=\"height: 24px;\">\n<td style=\"width: 33.802133850630455%; height: 24px;\"><span style=\"color: #808080;\">DATA SHEETS<\/span><\/td>\n<td style=\"width: 38.981862998913385%; height: 24px;\"><span style=\"color: #808080;\">INSTALLATION INSTRUCTIONS<\/span><\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"width: 33.802133850630455%; height: 24px;\"><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/Low-Voltage-2025_ProTec-T1SF-Series.pdf\">ProTec T1SF Series<\/a><\/td>\n<td style=\"width: 38.981862998913385%; height: 24px;\"><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/N_59A-500-300_ProTec-T1SF-Series_RevE.pdf\">ProTec T1SF Series<\/a><\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"width: 33.8021%; height: 24px;\"><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/G29-01-592_ProTec-T1SF-10_RevA.pdf\">ProTec T1SF 1+0<\/a><\/td>\n<td style=\"width: 38.9819%; height: 24px;\"><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/N_59A-596-300-ProTube-Type-T1HS_T1SF_Series_RevB.pdf\">ProTube T1SF Series<\/a><\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"width: 33.8021%; height: 24px;\"><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/G29-01-593_ProTec-T1SF-20_RevA.pdf\">ProTec T1SF 2+0<\/a><\/td>\n<td style=\"width: 38.9819%; height: 24px;\"><\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"width: 33.8021%; height: 24px;\"><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/G29-01-594_ProTec-T1SF-30_RevA.pdf\">ProTec T1SF 3+0<\/a><\/td>\n<td style=\"width: 38.9819%; height: 24px;\"><\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"width: 33.8021%; height: 24px;\"><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/G29-01-595_ProTec-T1SF-40_RevA.pdf\">ProTec T1SF 4+0<\/a><\/td>\n<td style=\"width: 38.9819%; height: 24px;\"><\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"width: 33.8021%; height: 24px;\"><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/G29-01-596_ProTec-T1SF-11_RevA.pdf\">ProTec T1SF 1+1<\/a><\/td>\n<td style=\"width: 38.9819%; height: 24px;\"><\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"width: 33.8021%; height: 24px;\"><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/G29-01-597_ProTec-T1SF-31_RevA.pdf\">ProTec T1SF 3+1<\/a><\/td>\n<td style=\"width: 38.9819%; height: 24px;\"><\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"width: 33.8021%; height: 24px;\"><a href=\"https:\/\/raycap.de\/wp-content\/uploads\/2021\/07\/G29-01-601_ProTube-T1SF-01_RevA.pdf\">ProTube T1SF 0+1<\/a><\/td>\n<td style=\"width: 38.9819%; height: 24px;\"><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>Surge Protection with Integrated Fuse.
