T0.4B is a 0.4 kW candidate for speed control of small motors on three-phase 380–480 V. The B braking-unit designation is separate from resistor selection and project-specific cabinet protection.
Technical specifications

Brochure and online entries differ in values/suffix scope. Electrical values are series comparisons; confirm braking/filter hardware on codes without B before ordering.
Application selection
Compare motor nameplate current with the 1.8 A output class.
Does B mean a braking resistor is included?
B identifies the braking unit; external resistance and delivery scope are selected separately.
Installation and commissioning
Qualified personnel must use the exact-model manual for installation and commissioning. Apply lockout before physical inspection, retain project/parameter backups and never bypass protective functions.
Quotation and supply
Send the three-phase motor label for a compact-drive offer.
Price, stock and lead time are not verified and require confirmation in the quotation.
Product comparison
MD200S0.4B-NC-INT – Separate model; not an automatic substitute.
Manufacturer-assigned product/enclosure visual. A separate full-code nameplate is unverified; some models share the image.
