The Siemens 3RV1913-1DA00-0FJ0 is an insulating combination housing with IP55 degree of protection, built to enclose and terminate a motor starter or breaker assembly in a panel that sees dust and water spray. It carries a neutral (N) and protective earth (PE) terminal, runs 72 mm wide on the DIN rail, and ships with a metric cable bushing from Benedikt & Jaeger — so the gland plate is already matched to the housing, not an afterthought.
The IP55 rating means this housing handles washdown spray and settling dust — fine for a machine-side enclosure or a standalone panel in a damp environment. The N and PE terminals are integrated, so you land the supply neutral and ground directly inside the housing without a separate terminal block. 72 mm on the rail is a standard two-module footprint; the metric cable bushing accepts a metric conduit or gland, so it wires up clean without an adapter plate.
