Certifications
How each certification is recorded
- CE marking
- Manufacturer's declaration (no official register exists)
Product availability has not been verified and is subject to change. Certification data is recorded as declared by the certifying applicant, not by OpenAxia.
Replacements
Current models named as replacements by the manufacturer, or with similar published specifications.
Replacement suggestions compare published specifications. They do not guarantee fit or compatibility. Check the motor head, crown and drive adapters, brackets, wiring and remote pairing with the manufacturer or a qualified installer before ordering. Mains-powered motors must be connected by a qualified electrician.
Not enough data to match by specification
A required value (torque, speed, diameter or supply) is missing, so the motor cannot be compared by specification.
- The manufacturer does not publish the diameter for this model.
