Flygt AST is a 3-phase starter series for manual and automatic operation of one pump with Flygt ENM-10 or NF5 level regulators. The starters are complete with all necessary components and include a main incoming supply switch, motor protection breaker with overload and short-circuit protection for each pump, monitoring relay type microCAS for built-in thermal contacts in pump. All internal control circuits as well as level switches are sourced from a 24V control voltage transformer.
The enclosure is of the factory built, wall mounted type with gasketed hinged doors, which may not be opened without a separate key or tool. The starters are well adapted for outdoor installation with a total degree of protection of IP 55, material 1.5 mm powder-enameled steel plate.
The Flygt AST series has not only been designed for reliable operation and easy installation. The AST are rigid enough to withstand all normal conditions in a temporary application, completely pre-wired and ready for easy start-up. All external connections are made from the bottom side, on suitable sized and clearly marked terminals. The panels are as standard delivered with wall mounting brackets.
The simplicity in the panel design with standardized electromechanical components makes start-up easy – no extra programming or expertise is needed for the start-up. This is also an advantage when most of the spare part components can normally be found on the local market.
