GE Multilin™ M60 Motor protection system Acceleration Time

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 theprocess 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.
