Motor starters and electronic switching devices

Switch motors safely and reliably with compact stand-alone, modular, and network-capable hybrid motor starters. The devices can be used wherever three-phase asynchronous motors, from 50 W to 3 kW, need to be reversed and protected.

Models with IP54 and IP67 degree of protection for field installation enable decentral, flexible, and modular installation. Transfer your process data easily and network your devices quickly with IO-Link.

The product range of hybrid motor starters consists of direct and reversing starters, which are available with various functions, such as emergency stop and motor protection.

Flexible and energy-efficient control of three-phase asynchronous motors: The CONTACTRON Speed Starter range is a state-of-the-art category of devices that bridges the gap between conventional soft starters and frequency converters. Its goal is to make variable speeds and smooth motor operations as easy and safe to use as possible, without the effort, complexity, or configuration work associated with a converter.

We provide a variety of stand-alone devices up to 7.5 kW. With a pluggable IO-Link module, the speed starter can be integrated into a network environment, configured, controlled, and monitored. This is particularly easy with preprogrammed function blocks.

This compact solution features all the functions necessary for simple operation with various speeds, from normal speed, creeping speed, and soft start all the way to energy efficiency and ramp functions. The Safe Torque Off (STO) function ensures a safe stop.

Electronic load relays and reversing load relays provide fast switching of DC motors. Reversing load relays reverse and brake DC motors up to 24 V/10 A without wear. Benefit from easy wiring with the integrated locking circuit and load wiring.

DC technology is the key to the sustainable power supply of the future. To this end, the innovative CONTACTRON ELR HDC DC circuit breaker in a particularly compact design combines the protection, monitoring, and switching of loads in modern industrial DC networks.
Benefit from wear-free hybrid technology, intuitive parameterization, data logging, network capability, and sustained efficiency increase due to energy recovery when operating your application.
