The Siemens 5SV9313-7CN25 is a 2-pole (1P+N) RCD-operated circuit breaker from the SENTRON 5SV9 series, combining overcurrent protection and residual current detection in a single 18 mm wide module. The Type A fault current detection covers pulsating DC and AC residual currents — the standard for most commercial and industrial circuits with electronic loads like VFDs or switching power supplies.
Ratings that matter for fit
The 25 A rating is at 30 °C ambient; at 40 °C it derates to 23.75 A, and at 50 °C to 22.25 A. The 1P+N configuration protects one phase conductor; the neutral is switched but not protected.
Snaps onto standard DIN rail — 18 mm width (1 width unit), 77 mm depth, 90 mm height. Installation depth is 70 mm. Supply can enter from top or bottom; mounting position is any orientation. The IP20 rating applies only when installed in a distribution board with conductors connected.
Overvoltage category III, touch protection included. The product is classified per DIN EN 61346-2 and DIN EN 81346-2 as function F. Energy limiting class 3. The manufacturer provides standard compliance documentation including RoHS and REACH declarations upon request.
