Description
Miniaturised double pole thermal circuit breaker with push-to-reset tease-
free, trip-free, snap action mechanism (R-type TO CBE to EN 60934).
Threadneck panel mounting. Suitable for line and neutral switching - the
thermal actuator operating on one pole simultaneously opens both poles
under overload conditions. Approved to CBE standard EN 60934 (IEC
60934).
Typical applications
Motors, transformers, solenoids, hand-held machines and appliances.
Especially suited to AC duties where the correct orientation of line/
neutral is not known/cannot be guaranteed.
All dimensions without tolerances are for reference only. In the interest of improved design,
performance and cost effectiveness the right to make changes in these specifications without
notice is reserved.Product markings may not be exactly as the ordering codes. Errors and
omissions excepted.
