The Siemens 5SL6340-6RC is a 3-pole miniature circuit breaker from the SENTRON 5SL series, rated at 40 A with a B tripping characteristic and a 7.5 kA breaking capacity. The B characteristic means it trips instantaneously between 3 and 5 times rated current (120–200 A), making it the standard choice for resistive and general-purpose loads in residential and light commercial panels where inrush is low.
