Temperature The Tmax XT circuit-breakers can be used in environmental conditions where the ambient air temperature varies between -25°C and +70°C, and can be stored at temperatures between -40 °C and +70 °C. Circuit-breakers fitted with thermomagnetic trip units have their thermal element set for a reference tempe- rature. For temperatures other than the reference, a trip threshold variation must be taken into account. Electronic trip units do not undergo any variations in performance as the temperature varies, but, in the case of temperatures exceeding +40°C, the maximum setting for protection L (protection against overloads) must be reduced, as indicated in the derating graph, to take into account the heating phenomena which oc- cur in the copper parts of the circuit-breaker which the phase current passes through. For temperatures above +70°C the circuit-breaker performances are not guaranteed. Environmental conditions The Tmax XT circuit-breakers are designed to operate in environments with a pollution degree of 3 accor- ding to the IEC 60947-2 Standard classification. Altitude Up to an altitude of 2000m/6561 ft, the Tmax XT circuit-breakers do not undergo any alteration in their rated performances. As the altitude increases, the atmospheric properties are altered in terms of composition, dielectric resistance, cooling capacity and pressure. Therefore, some performance aspects of the circuit-bre- aker (e.g. the maximum rated operating voltage and the rated uninterrupted current) undergo derating.

Electromagnetic compatibility Protection is guaranteed in the presence of interference caused by electronic apparatus, atmospheric di- sturbances or electrical discharges by using the electronic trip units and the electronic residual current relea- ses. No interference with other electronic apparatus near the place of installation is generated either. This is in compliance with the IEC 60947-2 Annex B + Annex F Standards, European Directive No. 2014/30/EC re- garding EMC - electromagnetic compatibility and UL489 Standard.

Degrees of protection The IP degree of the circuit-breaker can vary depending on the area considered and on the presence of acces- sories such as a motor or terminal cover. The following table indicates the degrees of protection guaranteed by Tmax XT circuit-breakers according to the prescriptions of the IEC 60529 Standard, in the different configurations. Furthermore, special kits are available to achieve IP54 with the MOE or RHD installed on the XT5, XT6 and XT7.

— Temperature performance

Circuit-breaker with magnetic only or electronic trip units and switch- disconnectors The electronic overcurrent trip units do not undergo any variations in performance as the temperature var- ies. However, even though heating does not affect the trip thresholds of the electronic trip units, in the case of temperatures exceeding +40°C it is advisable to reduce the maximum L (protection against overloads) setting to protect the copper parts of the circuit-breaker against high temperatures. The same considerations can be made for the switch-disconnectors and magnetic only circuit-breakers. The table below shows the maximum value at which, with terminals and lugs, the threshold of I1 of the over- current protection (L) must be set according to the ambient temperature.

Power losses To ensure service continuity of the plants, careful assessment of how to keep temperatures within accept- able levels is necessary to guarantee operation of all devices (e.g. by using forced ventilation in switchboards and installation rooms). The table below shows the dissipated power values per single pole at the rated current In for each fixed cir- cuit-breaker used. The total maximum dissipated power for a circuit-breaker used at 50/60Hz is equal to the power per single pole multiplied by the number of poles.

Power losses give indication of the heat generated under specified conditions. Measurement of power losses is performed on new samples in free air (according to Annex G of IEC 60947-2). The measurement of resistance cannot be directly related to the power loss of the device and it is not the proper parameter to assess poor performance of the poles.

— Characteristic curves Example of curves reading

Example 1 – XT3N 225 Trip curves for distribution (thermal magnetic trip unit)

Example 2 – XT2H 125 Specific let-through energy curves

These curves provide information about the tripping time of the thermal magnetic trip units.The red band indicates the hot trip times, that is with the breaker already loaded with its rated current once the overload has occurred. The blue band gives the cold trip times, that is with no current flowing into the breaker before the fault. The curves are assumed at reference air ambient temperature of 40°C and considering three phase overload with symmetri- cal and equilibrated currents. Let us consider an XT3N TMF In = 225A circuit-breaker. Based on the occurrence of the overload, either with the cir- cuit-breaker at thermal regime, or not, thermal protection tripping varies considerably. For example, for an overload current 3xI1, the trip time is be- tween 152.7s and 40.2s for cold tripping and between 40.2s and 6.9s for hot tripping. For fault current values higher than 225A, the circuit- breaker trips with the instantaneous magnetic protection I3.

This figure figure shows a sample graph of the specific let- through energy of the XT2H 125 circuit-breaker at a voltage of 220/230V. The prospective symmetrical short-circuit current is indicated on the x-axis, whereas the values of the specific let-through energy expressed in A2s are shown on the y-axis. The circuit-breaker lets through a value of I2t equal to 0.42 · 10^6 · A2s relative to a short-circuit current of 14kA.

The effective value of the prospective symmetrical short-cir- cuit current is given on the x-axis of the diagram, whereas the peak value corresponding to the prospective short-circuit cur- rent is indicated on the y-axis. For a value current of 22kA, the XT2L 125 circuit breaker with a thermomagnetic trip unit In = 125A limits the peak prospective short-current current to 18kA at a voltage of 600V.
