Page 7: Introduction Overview
Introduction Overview The 339 Motor Protection System is a microprocessor based relay providing suitable protection of medium voltage motors. The small footprint and the withdrawable option make the relay ideal for panel mounting on either new or retrofit installations. The combination of proven hardware, a variety of protection and control features, and communications, makes the relay ideal for total motor protection and control.

= the period in seconds corresponding to the nominal power system frequency. system The 339 thermal protection addresses the two distinct parts of the thermal limit curve: the motor starting limit, and the running limit. The start protection determines Time to Trip during motor starting, and the thermal overload curve determines Time to Trip during motor running.
Page 181: Start Protection
If the motor starting times are well within the safe stall times, it is recommended that the 339 standard overload curve be used. The standard overload curves are a series of 15 curves, each a multiple from 1 to 15 of a common curve shape based on typical motor thermal limit curves.

Normally Open trip relay terminals, referring to Figure 40, below. When control power is lost to the 339, the contactor will trip to ensure maximum protection. If process considerations are more important than protection, program non-failsafe and wire the contactor to the Normally Close trip relay terminals, referring to Figure 39 below.
Page 284 Each auxiliary relay can also be selected as either Non-Failsafe, or Failsafe. If an output is required when the 339 is not operational due to a loss of control power, select Failsafe auxiliary operation, otherwise, choose Non-Failsafe.
