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.
The time/current characteristic curve depends on the ambient temperature
prevailing. In order to eliminate nuisance tripping, please multiply the circuit
breaker current ratings by the derating factor shown below. See also
