Enclosure: Open type for watertight mounting (3ft. head —5 min.)
Each of the single element units consists of either a contact block or an indicating light element, with brackets for behind the panel mounting, plus the gasket and mounting plate for the front of the panel. On the indicating light, a lens is sandwiched between the gasket and the mounting plate. Mounting hardware is supplied for panel thicknesses as shown in sketches.
Indicating light elements are of the double lamp type. AC indicating lights have self-contained 440/1.8-1.8V or 117/ 1.8-1.8V ...
(3) When installed in the flush mounted configuration or in a remote control station enclosure, the transformers meet the shock vibration and temperature requirements of MIL-DTL-2212.
Selector switches for watertight mounting are available in two- or three-position configurations, self-centering or non-self-centering.
Self-centering two-position switches may be spring return from either side to center. Three-position self- centering switches may be spring return from either or both sides to center.
The basic selector switch element has a maximum of 8 stationary contact/terminals, 4 in each of two planes. Movable contacts consist of shaft mounted segments, available in several shapes to provide various circuit combinations for each of the two planes. Segments in the front and rear plane can be electrically connected by use of a jumper through the shaft assembly.
Segments can be assembled ...

All contacts are closed between limits, the switch construction is such that contacts "A" and "D" are normally open before they are mounted in the switch, and contacts "B" and "C" are normally ...
Rating: 110V AC Pilot Duty Three thermistors with the following characteristics are required:
Type: Negative Temperature Coefficient
Max. Resistance: 4000 ohms at 20°C
"Trip" Resistance: 450 ohms at desired "Trip" temperature
The Overtemperature Monitor measures the individual resistance of up to three thermistors which are attached to or imbedded in the motor windings. When one or more of the thermistors reaches its trip temperature (a resistance of 450 ohms), a control circuit relay (not supplied) is de-energized. The contacts of the ...
Ratings: Tachometer input 0 - 40V or 0 - 60V AC. Maximum voltage on terminals 1 through 6,100V DC. Maximum application voltage with control relay, 250V DC nominal (180V-355V submarine).
The Overspeed Trip Device is designed to prevent overspeeding on DC driven M-G sets, centrifugal pumps, etc., by measuring tachometer voltage of the driven machine and stopping the motor at a predetermined voltage. Stopping is accomplished by de-energizing the coil of a DC control relay (not included), which then opens the main motor controller ...
