(20) The relay must be adjusted to provide timing in the range of 0.05 seconds to three minutes.
Minimum time between successive operations — 0.2 seconds.
This timing relay can be supplied for either ON Delay or OFF Delay timing, but is not convertible from one to the other.
NOTE: Solenoid plunger may move during shock and cause contacts to operate. An energized timing relay may even recycle.

The N2000 Hand Held Programmer (N2000HHP) is designed to facilitate the setup of any of the various styles of the N2000 Overload Relay. The N2000 Overload Relay family contains many programmable motor protection and control features. The N2000HHP is able to access and modify all of the programmable features of the N2000 Overload Relay. These features may be accessed directly via the function select keys, or indirectly by means of stored setups.
The N2000HHP supports multiple customer definable setups. In addition to the direct programming functions, the N2000HHP also supports diagnostic and monitoring functions such as start/stop and current display. The N2000HHP is designed to provide enough voltage to the N2000 Overload Relay to ...

(118) The 9104 Heater Coils are for use on the following AC Magnetic Starters with the N750 Overload
Relay:
6962 6963
6966 6967
6968 6999
Heater Selection
Select the Heater based on motor
nameplate full load current.
Heater Coils are rated to protect 40°C
motors, and open and dripproof
motors having a service factor of
1.15 where the motor and the
controller are at the same ambient
temperature.
For other conditions:
(a) For 50°C, 55°C, 75°C rise motors and enclosed motors having a service factor of 1.0, select a heater coil two sizes smaller.
(b) Ambient temperature of controller lower than motor by ...
(84) The N750 overload relay with parallel reactor is intended to provide a slower time response to motor inrush currents than the standard N750 overload. This is done to eliminate nuisance overload tripping during long duration motor acceleration currents as required by a particular mechanical system.
The underlying principle states that as a reactor becomes saturated, its inductive impedance becomes very small in comparison to the heater coil impedance and consequently the reactor will handle the largest part of the inrush current, avoiding premature tripping. As the inrush current subsides to normal full load and the
reactor comes out of saturation, the reactor impedance increases to become very large in comparison to the heater coil ...
(3) The Size "0" Reverser Assembly is a special purpose control panel consisting of two N1310 contactors which are electrically and mechanically interlocked. The assembly is completely qualified to MIL-DTL-2212 and is ideally suited for reversing applications which have severe space limitations.
(2) The contact setting on this relay is retained or latched with a two-position toggle mechanism. No permanent latching magnets are used.
The set of contacts marked "A" is designed for control of the coil circuits and is not adaptable for other circuits. The set of contacts marked "B" is available for control of external circuits.
The coils are energized momentarily to position the switch and are de-energized by the opening of the corresponding "A" contacts on the switch.
