ATV21HD22N4 SCHNEIDER

Description

Product name ：ATV21HD22N4  SCHNEIDER Central control module
Product details:

These relays are field convertible from hand reset to automatic reset and
vice-versa. On automatic reset after tripping the relay, contacts will
automatically reclose when the relay has cooled down. This is an advantage
when the relays are inaccessible. However, automatic reset overload relays
should not normally be used with 2-wire control. With this arrangement, the
motor will restart when the overload relay contacts reclose after an overload
relay trip, and unless the cause of the overload has been removed, the
overload relay will trip again. This cycle will repeat and eventually the motor
will burn out due to the accumulated heat from the repeated inrush and
overload current. More important is the possibility of danger to personnel.
The unexpected restarting of a machine may find the operator or
maintenance man in a hazardous situation as he attempts to find out why his
machine has stopped.
