Bus tang connections are standardized to fit all applications. Four holes plus center slot. Holes are on 1.06” centers. The center slot is .5” x .75”.
| Water Requirements |
Amps RMS is achieved with a cooling flow rate of 1.2 gallons (4.5 liters) per minute at 40ºC water temperature. |
| Water Connection |
¼-18NPT tapped holes. |
| Cooling Block |
Copper-Nickel Plated. |
| Thermostat |
All contactors are supplied with a thermostat sensor, 70ºC open on rise, recloses at 58ºC, and is isolated to base to 2000 Volts. |
| MOV |
For MOV add suffix M to part number. |
| Service Tip |
It is recommended that power not be left on while water flow is off, as this is a cause for hose rupturing due to internal heating and arcing where water resistivity is low. |
