Siemens 3RM11071AA04 Safety Dol Starter

Product Description

The SIEMENS 3RM11071AA04 is a safety direct-on-line (DOL) motor starter designed for industrial motor control applications. A DOL starter connects a motor directly to the supply voltage at startup, providing full-load torque from the moment of energization. This unit incorporates integrated safety functionality, making it suitable for installations where machine safety requirements and motor protection must be addressed within a single compact device. It is typically installed by licensed electricians or industrial controls technicians working on motor branch circuit assemblies.

The 3RM11071AA04 is intended for use in industrial and commercial motor control applications where direct-on-line starting is appropriate for the connected load. Its integrated safety design supports installations subject to machinery safety standards, reducing the need for separate safety relays in the motor starter circuit. Typical installation scenarios include conveyor drives, pump stations, and fan motor control panels.

Key Features

• Integrated safety functionality eliminates the need for a separate safety relay in many motor control circuits
• Direct-on-line starting delivers full motor torque at energization
• Compact device design simplifies panel layout and reduces wiring complexity
• Suitable for industrial motor branch circuit protection and control

Compatibility

Designed as an OEM-style replacement or new-installation safety DOL starter for compatible industrial motor control panels and machinery safety circuits.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Disconnect and lock out all power sources before servicing or replacing motor control components. Verify that the supply voltage, motor full-load amperage, and safety category requirements of the application are confirmed before energizing the starter.
