Description

Overview

The Siemens 3SU1150-4BF11-1BA0 is a highly reliable component in the SIRIUS ACT control and signaling device range. This specific unit is a robust, 22 mm round, metal key-operated switch designed for secure and deliberate machine control. It utilizes a RONIS lock system with the common lock number SB30 and is supplied with two keys. Its shiny metal design ensures durability and a professional aesthetic in industrial panels.

Key Features & Benefit

  • Enhanced Security: The specific RONIS SB30 lock ensures only authorized personnel can operate or override machine functions, minimizing risk and ensuring compliance.

  • Industrial Durability: Constructed from metal with a shiny finish, it withstands harsh industrial environments, resisting wear, tear, and corrosion.

  • Simple Installation: The standard 22 mm diameter and included holder make it fully compatible with existing control panels and modular systems.

  • Reliable Connection: Screw terminals provide a robust, vibration-proof electrical connection suitable for long-term industrial use.

  • Modular System: Part of the flexible SIRIUS ACT system, allowing for easy expansion or change of contact blocks if needed (e.g., adding an NC contact).

Function & Application

Ideal for industrial and commercial control panels, machinery, and safety devices where secure key access is required. It provides reliable switching with controlled access to prevent unauthorized operation. Perfect for machine control, factory automation, and secure access systems.
