Motor brake relays

MINISTOP - High-performance and flexible device solutions

The factors of safety and efficiency are an important argument for the motor braking devices of DOLD. The wear- and maintenance-free devices can be easily installed, even in existing systems. The configurable braking current allows an optimal adjustment to machines and systems. Asynchronous motors up to 160 kW are reliably braked with the DOLD braking devices of the MINISTOP series. This allows your machine to be brought to a standstill in only ten seconds in accordance with the EU Machinery Directive and European standards.
