Siemens 3ra21151ba151bb4 Dol Starter S00 1.4-2A 24V Dc

Product Description

The SIEMENS 3ra21151ba151bb4 is a direct-on-line (DOL) motor starter in the compact S00 frame size, designed to start and protect small three-phase motors in industrial control applications. It operates on a 24-volt DC control voltage and accommodates a motor overload range of 1.4 to 2 amps, making it suitable for light-duty motor loads. Screw-type terminals provide a secure, field-wired connection. This device is typically installed by licensed electricians and industrial maintenance technicians working on motor control panels and machinery.

The 3ra21151ba151bb4 is intended for industrial motor control applications where a compact, self-contained DOL starting solution is required. Its S00 frame size fits standard DIN rail-mounted control enclosures and motor control centers. The 24-volt DC coil voltage is compatible with common PLC and low-voltage DC control circuits. Typical applications include conveyor drives, pump motors, fan motors, and small process machinery found in light manufacturing and building automation environments.

Key Features

• Direct-on-line starting method for straightforward motor control without soft-start circuitry
• S00 frame size for compact DIN rail installation in space-constrained panels
• 1.4 to 2 amp overload range for matched motor protection
• 24-volt DC control voltage compatible with PLC and low-voltage DC control systems
• Screw-type terminals for reliable, tool-secured field wiring

Compatibility

Designed as a direct-on-line motor starter in the S00 frame size suitable for three-phase motor control applications requiring a 24-volt DC control circuit and screw terminal wiring.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out all power to the control panel before wiring or servicing this starter. Mount on a standard 35 mm DIN rail and verify that motor full-load amperage falls within the 1.4 to 2 amp overload setting range before commissioning. Do not exceed the rated control voltage or motor current range.
