8340-G Datasheet, PDF (1/6 Pages) ETAL Group – Magnetic and Hydraulic-Magnetic Circuit Breaker

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).
