SIEMENS 3SU1000-5BP61-0AA0-Z Y11 Pushbutton / Mushroom Head Emergency Stop Button

‌1. Product Name‌
SIEMENS 3SU1000-5BP61-0AA0-Z Y11 Pushbutton / Mushroom Head Emergency Stop Button

‌2. Product Introduction‌
The SIEMENS 3SU1000-5BP61-0AA0-Z Y11 is an emergency stop (E-stop) pushbutton from the Siemens SIRIUS ACT product line. It is a modular, 22mm round operator with a mushroom head (red) and a black front ring/bezel (Y11), designed for immediate and safe shutdown of machinery and equipment in industrial control panels. It typically operates as a latching stop button with a twist-release or pull-to-release mechanism for reset.

‌3. Product Description‌
The SIEMENS 3SU1000-5BP61-0AA0-Z Y11 is a critical safety component in industrial automation systems. It belongs to the Siemens SIRIUS ACT family of modular actuators and is distinguished by its prominent mushroom head, a globally recognized symbol for emergency stop functions. Its primary role is to provide a highly visible and immediately accessible means for an operator to rapidly halt potentially dangerous machine motion or process. When integrated into a machine's safety circuit and control logic, pressing this button will cause a controlled but definitive shutdown of all hazardous energy sources, including drive systems such as those powered by ‌SIEMENS MOTOR‌. It meets stringent safety standards (like IEC/EN 60947-5-5) for emergency stop devices, featuring a latching mechanism that maintains the stop state until manually reset, preventing an automatic restart. Its rugged construction, high visibility (red mushroom head on a black bezel), and reliable positive-opening contacts make it a vital element for ensuring operator safety and complying with safety regulations in facilities utilizing ‌SIEMENS MOTOR‌ drives and other automated equipment.

‌5. Product Advantages‌
The key advantages of this E-stop pushbutton revolve around safety, reliability, and modularity. Its primary advantage is providing a ‌fail-safe, highly reliable means of emergency shutdown‌, crucial for personnel protection and equipment safety. The ‌prominent mushroom head design‌ ensures easy identification and quick access in critical situations. The ‌latching "stop and lock" mechanism‌ prevents accidental or premature restart, maintaining the safe state. As part of the SIRIUS ACT modular system, it offers ‌excellent design flexibility‌; the operator (5BP61) can be combined with various contact blocks (normally closed, positively driven, etc.) to match specific safety circuit requirements. Its ‌robust construction‌ withstands harsh industrial environments and frequent, high-impact use. The ‌positive-opening contacts‌ (if specified by the attached contact block) provide a high degree of safety integrity by ensuring contacts open reliably even in case of a welded contact. ‌Ease of integration‌ into existing SIRIUS ACT mounting frames and compatibility with the modular system simplify panel design and maintenance. These features collectively enhance machine safety, help meet regulatory compliance, and protect investments in machinery that often include components like ‌SIEMENS MOTOR‌.
