Usage and its scope of application RDX2-125High breaking circuit breaker is one current-limit type MCB of with over-load and short-circuit double protection. Circuit breaker is suitable for the circuit of AC 50Hz or 60Hz, rated operating voltage up to 230V/400V, rated current up to 125A, as the use of over-load, short-circuit protection of circuit, and it also can be used as infrequently connecting and breaking the electric device and lighting circuit. Circuit breaker confirms to IEC60947-2 and GB14048.2 etc. relevant standards. Normal operating condition and installation condition 3.1 Ambient temperature: -5 C ~ +40 C; Average value in 24h does not exceed +35 C. 3.2 Altitude height of Installation places does not exceed 2000m. 3.3 Condition of atmosphere When it is the highest temperature +40 C, the relative humidity does not exceed 50%, and it allows a certain high relative humidity when it is at relatively low temperature. For example, it reaches 90% when 20 C, and it should take special measurements when there occurring condensation due to the temperature variation. 3.5 Installation condition: Installing at the places that without obvious impact and vibration, as well as the medium without danger (explosion). 3.6 Installation mode: installed by TH35-7.5 installation rail. It usually adopts the vertical installation, and the gradient between the installation side and the vertical side does not exceed ±5°. 3.7 Installation category: II, III grade Product classification 4.1 Number of pole: IP, 2P, 3P, 4P 4.2 Rated current: 63, 80, 100, 125A 4.3 Rated operating voltage: 230V/400V www.peopIeelectric.com [email protected]
