Siemens 3VU1300-1ML00 Overview

Siemens products are manufactured in Germany and are designed for Automotive, aerospace, power generation, and electronics usage. They come with a 2-year warranty from MRO Electric. We also carry Breakers from other manufacturers such as FANUC and Yaskawa.

The Siemens 3VU1300-1ML00 is a versatile motor protection circuit breaker designed to meet a wide range of motor starter applications. With its combination of adjustable bi-metal thermal and fixed magnetic trip devices, it is a reliable solution that can cater to various customer requirements. This product is a testament to Siemens' commitment to providing high-quality automation and motor control solutions.

Key Features

  1. Adjustable Overload Protection: The 3VU Series includes an adjustable bi-metal thermal trip device that allows you to match the rated current of the motor you want to protect. This feature ensures that your motor is safeguarded against overload conditions, enhancing its longevity and efficiency.
  2. Factory-Built Instantaneous Trip: The circuit breaker comes with a factory-built instantaneous (magnetic) trip, which is carefully coordinated to protect both the load and the load conductors at their rated withstand levels without the need for additional adjustments. This ensures that your motor and associated components are safeguarded against short-circuit events.
  3. Phase Loss Protection: The 3VU Series is equipped with an internal differential mechanism that accelerates the trip time in the event of a phase loss. This feature is essential for preventing damage to the motor when a phase is lost in the power supply.
  4. AC and DC Compatibility: While primarily designed for switching AC, the 3VU Series is also suitable for use in DC circuits, providing flexibility in various applications.


  1. Individual Manual Motor Starter: The 3VU circuit breaker can be used to protect and manually control a motor. The selection is based on the Full Load Amps (FLA) of the motor and the type of enclosure required. It's crucial to adhere to the maximum circuit protection device allowed for installation.
  2. Individual Self-Protected Type "E" Combination Motor Starter: In many cases, the 3VU circuit breaker can serve as a part of UL508 Type E Combination Motor Starters. These starters are complete combination solutions and can be applied without the need for additional branch circuit protection. They are suitable for individual or group applications in multiple motor setups.
  3. Multiple Motor Applications: For multiple motor applications, 3VU devices, either with or without 3TF contactors, can be employed using Group Installation as per NEC 430-53. Detailed application information can be found in the Technical Information section.
  4. Self-Protected Combination Motor Controller: In multiple motor applications requiring self-protected UL508 Type E systems, the 3VU1300 MSPs can be used in conjunction with 3TF34 or 3TF44 contactors, with support for multiples up to 56A when paired with a 3VU91 current limiter.

Manufacturer: Siemens Product Type: Automation Starter, Circuit-Breaker, Motor Protector Description: Circuit-Breaker for Motor Protection up to 25A with Auxiliary Contacts (1 NO + 1 NC) with Screw Terminals. A-Release: 6 to 10A, N-Release: 120A.

In summary, the Siemens 3VU1300-1ML00 is a versatile and reliable motor protection circuit breaker designed to meet a wide range of motor starter applications, from manual motor starters to self-protected combination motor controllers. Its adjustable overload protection, phase loss protection, and compatibility with both AC and DC circuits make it a valuable asset in the field of motor control and automation.
