Description
PRK motor-starters of IEK trade mark are designed for managing and protecting three-phase asynchronous electric motors from overloads, short-circuit and open-phase operating conditions. They combine the functions of a modular circuit breaker serving for motor protection and a manual starter. These starters are used at industrial sites, agriculture and construction. It is possible to apply them for the local management of separate electric motors as well as residential and administrative building automation.
Life time:
10 years
Warranty:
3 years
Advantages
- High accuracy of operation.
- Convenient adjustment.
- Wide range.
Design Features
Power terminals and control circuit terminals have screw of the same size that allows the use of same screwdriver.
All parts of the circuit breaker are protected against direct contact.
Conjoint installation of two DK32 or DK32 and DK32/ AK32 contacts is possible.
Space and time saving during the installation of PRK32 series switch. Convenience and ease of regulation of thermal release actuation setup. With the use of the test button you can check the PRK32 switch without connecting to the electric circuit. Large temperature range allowing the use of switches.
