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.
