It suppresses the inductive voltage spike when the contactor coil de-energizes, protecting the DC control circuit from back-EMF damage. This part is a phased-out product. The official SIRIUS successor is the 3RT2936-1ER00-ZX90, which is the preferred replacement type. Snaps directly onto the front of SIRIUS Size S2 and S3 contactors. No additional wiring or DIN-rail space needed — the suppressor shares the contactor's coil terminals. Multi-unit packaging of 5 pieces per order code.","metaTitle":"SIRIUS 3RT1936-1ER00-ZX90 Surge Suppressor, 24 V DC, Size S2","metaDescription":"SIRIUS 3RT1936-1ER00-ZX90 24 V DC diode surge suppressor for Size S2/S3 contactors.
