Mounting is clip-on to the contactor itself, fitting sizes S0 through S3, and it can be installed in any position. That means you add transient protection without eating up DIN-rail space or reworking the panel layout — it snaps onto the contactor's own coil terminals. The varistor element absorbs the inductive kick when the contactor coil de-energises, protecting downstream PLC outputs or pilot relays from voltage spikes that would otherwise exceed their rated withstand. ## Temperature envelope and production status That covers most industrial cabinet environments and unheated storage before installation.","metaTitle":"Siemens 3RT5926-1BB00 SIRIUS Varistor Surge Suppressor","metaDescription":"Siemens 3RT5926-1BB00 SIRIUS varistor surge suppressor for contactors sizes S0–S3.
