The Siemens 3RV1923-1DA00-0FJ0 is an insulating combination housing rated IP55, designed to enclose a motor starter or circuit breaker combination. It includes integrated N and PE terminals and a lockable O-position feature, with a 72mm width and metric cable bushing from Benedikt & Jaeger. This is a current-production accessory — the lifecycle stage is listed as current, meaning it remains in active manufacture and supply.
What the IP55 rating means for deployment
IP55 means the housing is dust-protected and protected against water jets from any direction. For a combination housing on a motor starter or breaker, this suits it for washdown areas, outdoor enclosures, or food-and-bev zones where hose-down cleaning is routine. The N and PE terminals are pre-installed, saving panel-builder wiring time — no separate terminal block needed for the neutral and protective earth connections.
