unit settings - general comments The unit is the component that monirs the electrical current flowing through the circuit breaker and opens the circuit breaker in the event of a fault. c thermal-magnetic and electronic units detect overloads and shortcircuits; c Compact circuit breakers can also be fitted with a Vigi earth-fault protection module that s the circuit breaker in the event of an insulation fault (risk of electrocution or fire due earth leakage current). All Compact units (NS00 NS0) incorporate the reflex-ping system, an exclusive feature that ensures discrimination, even for very high short-circuit currents. overload protection Tripping time depends on the level of the fault: c the circuit breaker will within hours for a current equal : v 0% of for electronic units, v 0% of for thermal-magnetic units. c the circuit breaker must not for a load under 05% of.

environmental conditions ambient temperature operation Ambient temperature between 5 C and +0 C: The rated characteristics for Compact NS circuit breakers are guaranteed if the temperature of the air immediately surrounding the device is within the above range. Ambient temperature between +0 C and +70 C : Take in account the derating coefficients presented in the technical documents: c for circuit breakers with a thermalmagnetic unit, there is a natural drop in the thermal ping threshold (overload protection), c for circuit breakers with an electronic unit, there is a drop in the maximum setting authorised for overload protection. Ambient temperature above +70 C: Various systems the circuit breaker protect components from the effects of excessive temperature. t follows that continuity of service for the electrical installation is not guaranteed if the circuit breakers operate at temperatures greater than 70 C. Ventilation (natural or forced-air) should be provided for switchboards avoid temperatures greater than 70 C. srage and commissioning n their original packing, Compact NS circuit breakers may be sred at temperatures ranging from -55 C +95 C. Commissioning should be carried out at normal ambient temperatures (see above). However, commissioning may exceptionally be carried out at an ambient temperature ranging from -5 C -5 C. special aospheric conditions Compact NS circuit breakers operate within their rated characteristics in all normal climatic conditions. They have successfully passed (no drop in rated characteristics) the tests defined by the following standards: c EC -- : dry heat at +5 C, c EC -- : dry cold at 55 C, c EC --0 : damp heat (temperature + 55 C, relative humidity 95 %), c EC -- : salt spray. Compact NS circuit breakers are designed operate in industrial aospheres as defined in EC standard 97 (pollution degree i). t is however advised ensure that the circuit breakers are installed in correctly cooled switchboards without excessive dust. vibrations Compact NS circuit breakers are guaranteed against mechanical or electromagnetic vibration levels as specified in the following standards: c EC--, c Veritas NE, c Lloyd's Register of Shipping, c JS 70. Excessive vibration may however provoke untimely ping, loosening of connections or even rupture of parts.
altitude Compact NS circuit breakers are designed operate within their rated characteristics at altitudes up 000 metres. Above 000 m, modifications in the ambient air characteristics (dielectric withstand capacity, cooling capacity) result in the following derating: altitude (m) i 000 000 000 maximum operating voltage(v) 90 00 0 rated thermal current (A) at 0 C n 0,9 x n 0,9 x n electromagnetic disturbances Compact NS circuit breakers equipped with an electronic unit and a Vigi module are protected against: c overvoltages produced by electromagnetic switchgear, c overvoltages produced by aospheric disturbances and conducted by electrical networks (eg. lightning strikes), c devices emitting radio waves (radio transmitters, walkie-talkies, radar, etc.), c electrostatic discharges produced directly by operars. They pass EMC (electromagnetic compatibility) tests in compliance with the following international standards: c EC 55-- class : v 0 kv. / 50 µs overvoltage wave, v.5 kv MHz damped oscillary wave, c EC 000-- class : electrostatic discharges 5 kv, c EC 000-- class : 0 V/m radiated electromagnetec fields, c EC 000-- class : kv fast transient waves, c EC 000--5 class : v kv. / 50 µs voltage waves, v ka / 0 µs current waves, c EN 500- class B: conducted and radiated emissions in switchboards, c EC 97- annex F. The above tests ensure: c absence of nuisance ping, c overload ping times. 5
commissioning and exploitation prior commissioning new circuit breakers or following an extended shutdown A general check requires only a few minutes and eliminates any risks of incorrect operation due error or neglect. All checks must be carried out with the switchboard de-energised. For comparented switchboards, it is sufficient that all accessible sections be de-energised.

() extended shutdown or modifications in the switchboard () modification in the switchboard electrical tests nsulation and dielectric withstand capacity tests are carried out prior delivery of the switchboard. These tests are governed by applicable standards and must always be carried out by an authorised specialist. switchboard inspection Check that the circuit breakers are installed in a clean environment, free of dust and all installation debris (ols, wiring, chips, metal particles, etc.). compliance with diagram Check the conformity of devices with the installation diagram: v ratings and breaking capacities indicated on the rating plates, v unit identification (type, rating), v presence of additional functions (Vigi earth fault protection, mor mechanism, rotary handle, auxiliaries, indication and measurement modules), v protection settings (overload, shortcircuit, earth fault), v outgoing circuit identification on the front of devices, v for Vigicompact earth fault protection circuit breakers, check that the intermediate terminal shield is installed, otherwise the earth fault protection function is inoperative. device mountingstatus of connections and auxiliaries Check device mounting in the switchboard and the tightness of power connection. Check that auxiliaries and accessories are correctly installed: v mor mechanism modules or rotary handles, v accessories (terminal shields, door escutcheons, etc.), v connection of auxiliary circuits. mechanical operation Check the mechanical operation of devices: v contact opening, v contact closing, v ping using the "push ". operation of the electronic units and the Vigi modules Check the electronic units using the mini test kit or calibration test kit (see page ). Check the Vigi modules using the test butn on the front plate. This test guarantees ping in the event of an earth fault.
