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.

Protection and Control

The M60 motor protection system offers

comprehensive protection and control

solutions for medium to large-sized

three-phase motors.  The M60 includes

advanced automation and communication

capabilities, extensive I/O options, and

powerful fault recording features that can

simplify postmortem fault analysis and

help minimize motor downtime. As part

of the Universal Relay (UR) family, the M60

provides superior protection and control

that includes:

Motor Thermal Model

The M60 features an enhanced motor

thermal model consisting of the following

elements:

• Thermal limit curves – NEMA standard,

voltage dependent and customized

• IEC 60255-8 thermal overload curves

• Current unbalance biasing

• Independent running and stopped

exponential cooling curves

• Optional RTD biasing of the thermal

model to adapt to real-time

temperature measurements

• Compensation for hot/cold motor

conditions

The M60 thermal model integrates both

stator and rotor heating and cooling into

a single model.

FlexCurves™

For applications that require greater

flexibility, FlexCurves can be used to define

custom curve shapes. These curves can

be used to protect motors with different

rotor and stator damage curves, allowing

complete protection over the total motor

capacity.

Overtemperature Protection

The M60 supports up to 16 programmable

RTD inputs that allow for the configuration

of the alarm and trip temperature of each

RTD, detecting RTD shorting conditions,

and selecting RTD voting that requires

more than one RTD to detect an over

temperature condition before it will issue a

trip command.
