Dold have developed this very robust series of starter brake relay to meet the PUWER 98 requirments for the starting and braking of large woodworking machines.

The unit is designed to completly replace the exisisting machine starter and incorporates the following features. Star start times up to 40seconds, integral DC injection contactor, motor overload protection, fuse protection for the brake and control circuits.Most woodwork machine users and manufacturers are probably aware that the PUWER 98 regulations regarding the use and supply of new and refurbished woodworking machinery, requires that a reliable form of braking must be fitted.
