Magnetic and Hydraulic-Magnetic Circuit Breaker 840-G2... Description Single, two and three pole magnetic circuit breakers with trip-free mechanism and push/pull on/off manual actuation. A choice of fast magnetic only or hydraulically delayed switching characteristics (Stype MO or HM CBE to EN 6094) ensures suitability for a wide range of applications. Convenient threadneck panel or plug-in mounting, and with a white push button indicator band showing clearly the tripped/off position. Available with auxiliary contacts ( x N/O, x N/C) for status signalling and fitted with an unprotected shunt tap terminal as standard. Approved to CBE standard EN 6094 (IEC 6094). Typical application Control equipment, communications systems, power semiconductors. 840-G2... pole 2 pole Standard current ratings and typical internal resistance values Current Internal resistance (Ω) per pole rating (A) curve curves curves -F4/F -E/H/R -E2/H2/R2 0.02 8 244 2449 0.0 94 76 6 0.08.8 48 44 0. 2 94 84 0. 9.9 9 8 0.2 2 22.4 0. 2.44 9.9 9.7 0. 0.79.6. 0.7 0.9.. 0.2 0.79 0.77.2 0. 0.8 0.6. 0. 0.7 0.6.7 0.08 0.0 0.29 2 0.09 0.20 0.24 2. 0.044 0.46 0.8 0.028 0. 0.099 4 < 0.02 0.09 0.07 å< 0.02 0.040 0.08 6 < 0.02 0.026 0.026 8 < 0.02 < 0.02 < 0.02 < 0.02 < 0.02 < 0.02 2 < 0.02 < 0.02 < 0.02 < 0.02 < 0.02 < 0.02 6 < 0.02 < 0.02 < 0.02 20 < 0.02 < 0.02 < 0.02 2 < 0.02* < 0.02 < 0.02 0 < 0.02* < 0.02 < 0.02 40 < 0.02 0 < 0.02 * 0 % ON duty / 60 min.
