The MOTUS C14 electronic motor starter family sets new standards in the protection of machines and systems: Fuseless short-circuit protection that switches off the machine or system 100 to 1000 times faster in the event of a fault than a conventional fuse-link or a circuit breaker and allows it to be switched back on afterwards.
To allow users to choose the right level of functionality, the MOTUS C14 is available in two versions:
MOTUS C14 Basic is the straightforward entry into C14-Technology – an electronically protected direct and reversing motor starter, purpose-built for quick commissioning, high availability and easy integration.
MOTUS C14 Connect Plus is the motor management system for connected machines and systems, offering extended diagnostics, measurement and connectivity when maximum transparency and system integration are required.
Two variants with the right range of functions:
Choose exactly the solution your application needs
We are expanding the MOTUS C14 family with a new version. The basic version combines the advantages of C14-Technology as a direct and reversing motor starter in an all-in-one solution. It is ideal for applications with clearly defined requirements, where protection and system availability are key but the full functionality of a motor management system is not needed.
At the same time, we have redesigned the MOTUS C14 Connect Plus and can now offer the full functionality of the motor management system even more cost-efficiently.

Ultra-fast short-circuit handling: In the event of a fault, shutdown occurs within 10 microseconds The MOTUS C14 reacts faster than any fuse while maintaining minimal let-through energy.
Thanks to the extremely fast shutdown in the event of a short circuit and the resulting low I²t value, the device is subjected to only minimal stress.
The MOTUS C14 offers users extensive possibilities for utilizing communication and measurement data, ranging from readable service, measurement, and maintenance data to diagnostic data for the motor and busbar, as well as the device’s self-diagnostics and data logging functions.
Simple parameterization and an intuitive, interactive operating concept round off the intelligent functions of the MOTUS C14.
After the fault has been rectified – for example, after eliminating a short circuit – the load can be switched on again. The user acknowledges that the fault has been resolved and can restart the end device directly.
Through the compact construction and innovative Wöhner design, the MOTUS C14, with a width of just 22.5 mm, can reduce installation space by 75% compared to the previous construction of motor starters. An adaptive ventilation concept ensures reliable ventilation in the smallest spaces.
Two variants with the right functionality – so you can choose exactly what your application needs.
The MOTUS C14 electronic motor starter covers various application areas and makes controls convenient and safe. It switches 3-phase motors up to 3 kW or up to three 1-phase motors in the cabinet against the neutral conductor or in the star point. Among its many different applications are use as a direct and soft starter for motors (IE2, IE3 and IE4), reversing and soft starter for motors (IE2, IE3 and IE4) as well as a heating controller for machines.
Users receive all necessary data for monitoring operation and diagnosing faults via the communication interfaces, even in remote operation:

In the event of a fault, icons immediately indicate which error occurred. The arrow buttons can be used to perform parameterization directly on the device (CONNECT PLUS).
The interactive menu navigation of the commissioning wizard simplifies the input of the parameters and immediately detects errors. As a result, an incorrect combination of parameters is reduced to a minimum. Clear signalling on the display as well as colour LEDs at various positions on the device make the MOTUS®C14 easy to understand and operate.
In the basic version, the rated current can be parameterised via the Wöhner ServiceTool. Designed for simplicity and fast deployment, no additional parameters – such as the trip class – need to be configured. Fault conditions are indicated via red LEDs in the main actuator and on the housing. Detailed information can also be accessed via the ServiceTool.
The entry version for applications with clearly defined requirements is available in the 2.6 A current rating. It can be used as a direct and reversing motor starter for IE2, IE3 and IE4 motors.
Commissioning and parameterisation are carried out via the ServiceTool. A clear status LED supports fast identification of operating states and faults.
Diagnostic data can be accessed via the ServiceTool. The basic version relies on a simple signalling concept.
The premium version is available as an intelligent motor management system in the current ratings 2.6 A and 6.6 A. It can be used as a direct, reversing or soft starter for IE2, IE3 and IE4 motors, or for switching resistive loads. In addition to 3-phase operation, up to three 1-phase loads can be operated.
Commissioning and parameterisation can be carried out either directly on the device via the display and arrow buttons, via the ServiceTool or via the communication interface. Through this interface, the device can also be integrated into higher-level control systems in order to analyse and utilise measurement and diagnostic data in a targeted manner.
Both MOTUS C14 versions are available in dedicated versions for the CrossBoard, 30Compact, 60Classic and Panel basic systems.
The simple, tool-free mounting via the CrossLink interface also makes life easy for users. The MOTUS C14 can thereby establish contact on all basic systems. In addition, the product series is equipped with a pluggable load connection and a pluggable connection for classic control or IO-Link wiring.
The MOTUS C14 product series can directly establish contact on the CrossBoard and, with the CrossLink adapter, can also easily be integrated in the 30Compact, 60Classic and Panel systems and – via the EQUES 185Power basic system adapter –i n the 185Power system.
Furthermore, the innovative basic technology of the MOTUS C14 can be freely incorporated in other solutions – for entirely new possibilities, e.g., in machine construction.
A separate service tool for MOTUS C14 simplifies commissioning, parameterization and data logging for users. The software can be downloaded after completing a brief registration.
The ServiceTool offers the following functionalities:
System software:
Use the ServiceTool for the MOTUS C14 as a convenient tool for a number of tasks, such as the management of warning and fault messages (reading out the history for error analysis, faster fault isolation and troubleshooting), manual operation for the manual control of the drive (right – left – off, soft start) and data logging (display of data for preventative maintenance and early fault detection, displays of current process data such as current, voltage and power).
