Description
The model range covers ET3SM-400, -500, -630, -800, -1000, -1250 and -1600, with the number in the designation corresponding to the power in kVA. The enclosure is quickly disassembled to reach the winding taps and adjust the parameters. Cables are brought in through the floor, which orders the installation and additionally protects the entries mechanically. The enclosure is painted with powder paint RAL 7035, or another colour at the customer's wish. Terminals are made as clamps with a cross-section of 10–240 mm² or copper busbars, cooling is natural air AN, and the working position is vertical. Made to EN/IEC 60726 and EN/IEC 61558, and depending on the order to the rules of GL, PRS, RMRS, RINA, LR, BV, DNV, ABS and NATO. The factory has kept a reference list of marine deliveries since 1994. The ambient temperature is 45 °C.
How to choose
The power is chosen from the series 400, 500, 630, 800, 1000, 1250 or 1600 kVA according to the total load of the circuits. Insulation class H (180 °C) or F (155 °C) determines the thermal margin, and it is agreed with the project and the ship's register. For repair crews, safety transformers ET3oM are made, and for thruster devices the starting autotransformers EA3RM-Compact. For land installations with circuit isolation see ET1MED, and for railway cabinets ET3KOL.
