11 / 20 page 6 • EN60947-5-1 EN standard same as IEC947-5-1 • Utilization categories The following examples express the classification of switches by category of use. • Rated impulse withstand voltage (Uimp) The peak impulse current value which enables the switch to resist without insulation breakdown. • Rated enclosed thermal current (Ithe) The current value that enables cur- rent to flow without exceeding the specified maximum temperature in the recharging contact switch. If the pins are made of brass, the maxi- mum temperature limit is 65°C 149°F. • Conditional short circuit current The current the switch can resist until the short circuit protection device is activated. • Short circuit protection device A device that protects the switch from short circuits through a circuit break (breakers, fuses, etc.) • Switching overvoltage The surge momentarily generated when a circuit is closed. Must be lower than the Uimp value. • Pollution degree Expresses in levels the environment in which the switch is used. The four levels are shown below. Limit switches come under contami- nation level 3. Glossary relating to the EN60947-5-1 • Rated operational voltage (Ue) The maximum rated voltage for switch operation. This must never exceed the maximum ratings insula- tion voltage (Ui). • Rated operational current (Ie) The maximum rated current for switch operation. • Rated insulation voltage (Ui) The maximum rated current value which guards the switch’s insulation functions, forming the parameters for the resistance values and the mount- ing distance. Current type Category Contents AC AC-15 Controls electromagnetic loads in excess of 72VA (Volt Amperes.) DC DC-12 Controls resistance loads and semiconductor loads. Pollution degree Contents 1 No contamination or, even if conta- mination is present, only non-con- ducting contamination is generated. 2 Normally, only non-conducting cont- amination is generated, but there remains the possibility of temporary conducting contamination when the circuit is formed. 3 Conducting contamination is gener- ated, or else dry non-conducting contamination is generated by cir- cuits which can be anticipated. 4 Permanent conducting contamina- tion is generated by dust, rain, snow, and other conductors.
