MAX POWER THRUSTER CT550 ELEC 30KW 3PH DUO CLASSIC Ø400

  • Exact product-code verification required
  • Availability and included scope confirmed by quotation
TECHNICAL BOUNDARY

Items that require written confirmation

Conflicts and compatibility limits are retained so reference data is not converted into an unsupported promise.

  • Fixed tunnel installation
  • Electric drive
  • Voltage- and product-code-specific selection
  • The official product table and official data sheet publish different AC voltage upper bounds (420 V versus 440 V); the exact voltage range is intentionally omitted.
  • A published dimension marked D must not be substituted for the nominal 400 mm tunnel diameter.
  • Catalogue reference does not establish ERBA stock, authorized-dealer status, warranty route, regional approval or guaranteed availability.
  • The written quotation confirms the final manufacturer, model, documents, warranty path, delivery and included services.
SELECTION INPUTS

Selection data for CT550 AC

Confirm the vessel, installation geometry, power source, controls, duty and documentation needs before applying any reference value.

Vessel & duty

Define hull, displacement, windage, operating conditions and manoeuvring duty.

  • Vessel type, newbuild / retrofit / replacement and operating area
  • Length overall, beam, draft, displacement and loading condition
  • Hull material, thickness and available structural drawings
  • Windage profile, superstructure and expected manoeuvring conditions

Installation

Confirm tunnel or retractable geometry, immersion, structure, drainage and access.

  • Bow, stern or combined requirement and desired operating duty
  • Existing or proposed tunnel diameter, position, immersion and clearances
  • Available internal space, access, drainage and maintenance route
  • DC voltage and battery capacity or AC supply, phase and frequency

Power & scope

Coordinate electrical or hydraulic supply, controls, documents and delivery boundary.

  • Hydraulic pressure, flow, return, cooling and filtration if available
  • Control stations, joystick, proportional control and remote requirements
  • Flag, class, client documentation and inspection requirements
  • Delivery location, schedule and installation / commissioning boundary
FREQUENTLY ASKED QUESTIONS

CT550 AC Electric Tunnel Thruster Reference questions

These answers preserve the technical-review and written-quotation boundary for every reference route.

No. The detailed catalogue pages use current Max Power models as clear reference examples because ERBA Marine deals with this equipment, but ERBA can also review other supported manufacturers or a project-configured package. The quotation confirms the final make and model.

No. Published values are manufacturer-reference data and depend on the exact variant, voltage or hydraulic supply, installation geometry, immersion and operating conditions. ERBA Marine confirms the quoted configuration only after technical review.

Yes. Send the existing model and nameplate, tunnel or hull-opening dimensions, vessel drawings, power information, controls, photographs and the required new duty.

Continuous or extended duty must not be assumed. Duty limits depend on the exact electric or hydraulic system, cooling, batteries or power pack, controls, installation and current manufacturer instructions.

No. It is a current manufacturer-reference family page. Vessel data, installation geometry, duty, power, controls, documents and availability must be reviewed before the written quotation confirms the final make, model and product code.
