It mounts into the 3RV19 housing family, covering sizes S00 through S2. This is the part you pull when the panel builder's BOM calls for a visual status lamp on a motor starter or circuit breaker enclosure. The color disc ships with red, green, and clear inserts — you swap the lens to match the circuit state you're indicating. The glow lamp operates on 110-120V AC or DC, so it works across both control supply types without a separate rectifier. Housing sizes S00 through S2 cover the full 3RV19 breaker range, meaning one indicator SKU fits the whole panel family.","metaTitle":"Siemens 3RV1903-5BA00-0FJ0 Indicator Light, 110-120V AC/DC","metaDescription":"Siemens 3RV1903-5BA00-0FJ0 indicator light with glow lamp, 110-120V AC/DC, red/green/clear disc for 3RV19 housing S00-S2.
