Mechanical Jam
The mechanical jam element senses
increased loading associated with
process or load related faults such as an
overloaded conveyor. A programmable
delay setting can be used to allow the
process to attempt to clear itself before
issuing a trip.
Acceleration Time
The M60 protects the motor from
overheating in cases of abnormal
loading during motor starts. The motor
can be tripped if the motor does not
reach a running condition within the
programmable motor acceleration time.
Stator Differential
The M60 provides stator differential
protection for fast clearing of stator phase
faults. Advanced CT saturation detection
algorithms and dual-slope characteristics
are incorporated for increased security
during heavy faults.
Short Circuit Protection
Short circuit overcurrent protection
protects damage to the motor during a
locked rotor condition. The M60 comes
with up to 8 instantaneous overcurrent
elements that can be configured for
protection, alarming, and control during
locked rotor conditions.
