It mounts directly onto the contactor, no separate bracket or wiring harness needed — clean the coil noise without adding panel clutter. ## Lifecycle reality: phased out, successor ready The 3RT1926-1CE00 is a phased-out product. Siemens lists a direct successor: the 3RT2926-1CE00. If you're maintaining an existing panel with the old part, the new one drops into the same S0 footprint — no need to re-engineer the mounting or wiring. For new builds or BOM updates, the preferred replacement is the 3RT2926-1CE00. For legacy spares, we source the original 3RT1926-1CE00 through independent distribution — quantities are lot-specific and confirmed at RFQ. No pinout or mounting changes between the two; it's a straight swap.","metaTitle":"Siemens 3RT1926-1CE00 SIRIUS Surge Suppressor, 240-400V AC","metaDescription":"Siemens 3RT1926-1CE00 SIRIUS RC-element surge suppressor, 240-400V AC, for Size S0 contactors.
