The circuit breakers, adopting intelligent controller with precise selective protection and multi-functions, have complete protection functions and are especially suitable for power distribution network which needs to improve power supply reliability and avoid unnecessary power failure. Of which, the PT40-2H/PT40-3H intelligent controller, with communication interface, is convenient to be connected to the field bus and can realize remote functions of "remote measurement", "remote adjustment", "remote control", and "remote communication", so as to meet the requirements of automated control. To configure leakage mutual inductor and the matched intelligent controller can also realize electric leakage protection. The impulse withstand voltage of circuit breakers at an altitude of 2000m can reach 8kV (to correct of the same altitude according to the standard, 12kV at most). The circuit breakers of 1,000A or below (rated operating current) can protect the motor from overload, short circuit , under voltage and ground fault in the network of AC50Hz and 400 V, and can use for infrequent starting of the motor under normal Operating environment Ambient air temperature should be not higher than +40, and the average temperature within 24h should be not higher than +35. The lower limit of ambient air temperature is -5. Note: For using under ambient air temperature of higher than +40 or lower than -5, users should negotiate with the manufacturer.

The new FORMULA family consists of two frames, A1 and A2, which reach up to 100A and 250A respectively. Both frames are available in the fixed version, with front terminals. The protection trip unit has fixed thermal and magnetic threshold values for putting the circuit breaker into service more rapidly. This way selection becomes precise. A reduced number of sales codes simplifies selection and makes ordering easier. Installation is easy and the circuit breaker is ready for use immediately. All the molded case circuit breakers in the FORMULA family are constructed in accordance with the following construction characteristics: â?¢ Double insulation â?¢ Positive operation â?¢ Isolation behavior â?¢ Electromagnetic compatibility â?¢ Topicalization â?¢ Reverse feedable power supply â?¢ Versatility of the installation. It is possible to mount the circuit breaker either in the horizontal, vertical, or lying down position without undergoing any derating of the rated characteristics; â?¢ No nominal performance derating for use up to an altitude of 6562 ft. Above 6562 ft, the properties of the atmosphere (composition of the air, dielectric strength, cooling power and pressure) change, having an impact on the main parameters which define the circuit breaker. The table below gives the changes to the main performance parameters.
Air Circuit Breaker: Air circuit breakers can be used both as circuit-breakers for general protection (of plants, of user complexes, of electric lines) and as protection circuit-breakers of electrical machines (generators, motors, transformers, capacitors). Modularity and compactness of Emax air circuit-breakers considerably simplify the construction of the switchboards. The accessories are always fitted from the front simply and rapidly, without the need for cabling and in complete safety. The simplicity of these operations means that any personalisation required can be carried out directly by the end customer.

It can happen very quickly: Thoughtlessly touching a currentcarrying cable; a faulty connecting cable; or a device fault. Happy are those who have protected their electrical system with the right RCCB. In the event of damage, it is activated within a fraction of a second, breaks the circuit and thus possibly saves lives. In this way, everyday exposure to current gets considerably safer. For new installations and extensive renovations of commercial and private electrical systems, the use of RCCBs is mandatory according to VDE 0100-410 since June 2007 anyway. This also refers to all outdoor electrical systems and electric circuits. Our product range offers you the right RCCB solution for every field of application because - in addition to devices of type A (sensitive to pulsating currents) and type B (sensitive to universal current) for the German market - we can also deliver devices of type AC (sensitive to alternating current - not approved for Germany) for export.
