Engineered to serve as the exact replacement part for original installations, it helps you keep your bill of materials aligned while minimizing downtime during replacements or upgrades.\u003c\/p\u003e \u003cp\u003eThis model features an integrated auxiliary switch with a normally open contact, enabling straightforward status signaling and interlock control without adding extra components to your panel. It’s the kind of detail that makes electrical diagrams simpler and wiring harnesses more compact in tight enclosures.\u003c\/p\u003e \u003cp\u003eWhy this matters in real-world terms: when you swap in the 3RH19111BA10, you’re not just replacing a block—you’re preserving the electrical footprint, mounting pattern, and compatibility with your existing wiring schemes. That means faster repairs, fewer surprises during maintenance, and improved reliability across your automation cabinet. It’s especially valuable for replacement projects, long-term spares planning, and any scenario where BOM integrity is non-negotiable.\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Siemens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 3RH19111BA10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Terminal Block\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuxiliary Switch:\u003c\/strong\u003e Normally Open\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eThis terminal block is ideal for control panels, machine enclosures, and automation cabinets where orderly wire termination and a built-in signaling path are priorities.
