Magnetic and Hydraulic-Magnetic Circuit Breaker 8340-G2... Description Single and two 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 (S- type MO or HM CBE to EN 60934) 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 (1 x N/O, 1 x N/C) for status signalling. Approved to CBE standard EN 60934 (IEC 60934). Typical application 1 8340-G2... 1-pole 2-pole Control equipment, communications systems, power semiconductors. Standard current ratings and typical internal resistance values Technical data Current rating (A) Internal resistance () per pole For further details please see: 5 Magnetic and Hydraulic-Magnetic Circuit Breaker 8340-G2...
