Insulation System and Operating Conditions

The document specifies an insulation system designed for operation at 400 Hz and 2400 revolutions per minute (r.p.m.). The ambient temperature for continuous operation is set at 40°C. The insulation classes mentioned include Class H and Class F, with efficiency percentages provided for Class H.

Accessories and Connection Series

Various connection series are available for the equipment, including Series Star, Series Delta, Parallel Delta, and Parallel Star configurations, all operating at 400 Hz. These configurations correspond to different power ratings and performance characteristics.

Performance Specifications

The equipment is rated for three-phase continuous operation with a power factor of 0.8. Efficiency values range from approximately 90.2% to 92.9% depending on the model and configuration. Noise levels at 2400 rpm vary between 74 dB(A) and 88 dB(A). Air volume flow rates are specified between 310 and 430 cubic meters per minute.

Mechanical and Thermal Protection

Mechanical protection ratings include IP21, IP23, IP45, and IP55, indicating varying degrees of ingress protection. Thermal protection is provided by devices such as PTC bimetallic devices and PT100 sensors. Heaters are included as part of the thermal management system.

Physical Dimensions and Weight

The document provides detailed overall dimensions for different forms (B3-B14 and MD35) and types (HCP34S/20 and HCP34L/20). Dimensions are given in millimeters, including length, diameter, flange sizes, and bolt hole counts. Weights are specified in kilograms, with examples such as 58 kg, 75 kg, 95 kg, and 115 kg depending on the model.
