DC circuit breakers
Motor starters and electronic switching devices
Switching devices are essential for industrial automation. We offer motor starters and electronic switching devices for a wide range of applications: hybrid motor starters for reliable motor switching and reversing. Motor starters for DC motors are used for wear-free switching, reversing, and braking. Speed starters provide intuitive operation, different speeds, soft start, and Safe Torque Off (STO). DC circuit breakers protect, monitor, and switch high DC loads in the DC grid.
Product categories
Speed starters The CONTACTRON Speed Starter is the simplest operating concept on the market in the device class between soft starters and frequency converters.
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.
Motor starters for DC motors Switch your DC motors quickly and reliably
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 circuit breakers Protect, monitor, and switch DC loads entirely without electric arcs
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.
