The Helmke CDDOR400-04 is a 300 kW three-phase squirrel cage motor designed for demanding industrial environments. Operating at a voltage of 6,000 V and a frequency of 50 Hz, this 4-pole motor delivers a rotational speed of 1,500 1/min in continuous duty (S1). It features an IP 55 ingress protection rating, IC 411 cooling, and an Ex d IIC T4 Gb explosion protection rating, making it suitable for hazardous areas. Built in an IM B35 mounting form with a left-hand direction of rotation and finished in RAL 7030, it utilizes rolling bearings (Waelzlager) and achieves an efficiency of 94.10% with a power factor (Cos phi) of 0.86. The unit is engineered for ambient temperatures ranging from -25 to +45 °C and a maximum installation altitude of 1,335 meters. Comprehensive thermal monitoring is provided via six slot resistance thermometers PT 100 for the windings and two resistance thermometers PT 100 for the rolling bearings, alongside a 220-240V anti-condensation heater (min. 200V, max. 264V) and a neutral point terminal box with 3 terminals. Insulation corresponds to thermal class F with utilization to class B. This motor serves as a direct replacement for the Loher type DHSW-400LK-04D.
