Sure Power 400/230VAC 3 Way x 3 Phase Reverse Polarity Lock Out Module - Checks Polarity of 3 Phase+N 400/230VAC Shore Power Supply (3P3WM)
Specifically designed for use in Marine Survey Vessels
The module will check for correct phase sequence, under and over voltage, phase loss, correct polarity and that the earth is present on a 3 Phase + N 400/230 VAC systems. If the polarity is correct and the earth is present then the module will switch 240volts to energise a contactor allowing power to go to the switchboard giving you sure power
overview
Sure Power 400/230VAC 3 Way-3 Phase Reverse Polarity Lock Out Module (3P3WM)
Checks Polarity of 3 Phase+N 400/230VAC Shore Power Supply
Checks for correct phase sequence, under and over voltage, phase loss, correct polarity and that the earth is present on a 3 Phase + N 400/230 VAC system
The 3 Phase lockout sensing modules are designed to monitor the incoming supply to ensure a safe and compliant connection to the vessel.
The module will check for correct phase sequence, under and over voltage, phase loss, correct polarity and that the earth is present on a 3 Phase + N 400/230 VAC system. If all the sensing requirements are met the module will output a maximum switching current of 3A @ 250V / AC1 for control of the supply connection to the vessel. If these conditions are not met, the module will not allow supply to the vessel.
This sensing module has been designed for areas where the installation of the unit is open to the effects of adverse weather conditions.
National Standard for Commercial Vessels* (NSCV) require:
- a means of checking the phase sequence in relation to the vessel's system
* National Standard for Commercial Vessels Part C - Design and Construction Section 5 - Engineering Subsection 5B - Electrical (Edition 2)
