AC METRIC ELECTRIC MOTORS
Specification
Supply
Designed for operation at normal voltages 380-415 and rated 400v + or – 10%.Other voltages available to order.
Up to 3kw can accept 230v 3 phase supply suiting use with a single phase inverters. From 4kw, windings are 400/692v to suit star/delta starting. This gives a softer start with lower currents.
Motors suit 50/60 Hz operation
Efficiency
To the level Eff2 defined by CEMEP and the European Commission.
Ambient Conditions
Ambient temperatures between -15 and + 4C and sites up to 1000m a.s.l. Derating apply outside these limits. Relative humidity 30-95% without condensation heaters. Enclosure class IP55 with class F insulation.
Protection
Rated for continuous duty S1. Motors up to 132 frames have klixon thermal switch. From D160 frame three PTC thermistors are fitted in the winding.
Construction
Designed and constructed meeting the European Directives for Low Voltage, Machinery and EMC. Complies with relevant IEC, BS, VDE and Din standards.
