PSR72-600-70 softstart 37kW przy 400V

The softstarter PSR72-600-70 has a rated maximum operational current of 72 A with an operating voltage span from 208...600 V AC.
The rated control voltage is between 100...240 V AC at 50/60 Hz.
PSR features a two-phase control soft start and stop through a voltage ramp.
It has built-in bypass for easy installation and energy saving.
A RUN and a TOR signal is available from a relay output in NO (normally open state).
The start/stop ramp and time is easy to set by three potentiometers on the front.
PSR is often used in combination with a manual motor starter (MMS) from ABB, so mechanical connection kits are available.
Another popular option is Fieldbus communication, which can be enabled by an external adaptor and a Fieldbus plug.
The PSR range is our most compact softstarters with basic functionality and values.
They are suitable for small three-phase motors with nominal currents from 3...105 A and can manage up to 100 starts per hour.
Common applications are, for example, pumps, fans, compressors, and conveyors.
