Source-stated values require the stated unit, configuration and loading conditions. No price, stock or approved rating is asserted.
The dedicated source page states spring-adjustable 250–400 N·m torque, 300 mm brake wheel, Ed30/5, 65 kg, S1 plus S3-60% at 1200 cycles/h, standard 380 V 50 Hz three-phase supply and optional 440–460 V 60 Hz. Environment and corrosion options remain source conditions.
View original sourceLettered dimensions are available with explicit mm units on the dedicated product page. The unqualified n=12 is excluded from the dimension table; its meaning and unit are not inferred.
View original sourceThe dedicated page uses E=1.0 mm retreat/clearance and F/G1/G2=255/130/295 mm. The series A-table uses E/F/G1/G2=255/130/295/330 mm under its dimension header. These four symbols have conflicting source scopes. Preserve both sources separately and obtain the matching approved diagram; neither page silently corrects the other.
View original sourceA one-page manufacturer PDF lists YWZ8/YWZ9 lining dimensions and wear limits in mm, including a YWZ9-300 row. This is a lining component reference; it does not confirm the lining material, BOM or fitment of YWZ9-300/E30A. No drawing number or approved revision is established.
View original sourceRequest the numbered drawing/revision, approved interfaces, lining material, wear-compensation and release/monitoring options for the ordered A-version. The source describes a service brake for non-hazardous areas; holding-only or explosion-protected suitability is not established.
