Description
The ebmpapst 624H (WWCD060AJEFS/9292207009) is an ultra-high-speed 24 V DC Axial Fan with dimensions of 60 x 60 x 25 mm, specifically engineered for critical thermal management in Siemens drive systems and compact industrial control units. Driven by an electronically commutated external rotor motor with integrated auto-restart locked-rotor protection and reverse polarity protection, this unit provides a precise Max. Power Consumption of 1.9 W and a Max. Current Draw of 0.08 A at 24 V DC. Operating at an elevated rated speed of 6850 RPM, it delivers optimized airflow to ensure efficient heat extraction in high-density electronic environments. Constructed with a glass-fiber reinforced PBT plastic housing and a 3-blade impeller featuring precision ball bearings, this 66 g unit ensures maximum cooling efficiency and long-term mechanical stability for integrated industrial switchgear systems at the end.
