The Siemens 5SV9316-6PK25 is a single-module RCBO (Residual Current Circuit Breaker with Overcurrent Protection) combining a 25 A B-curve MCB and a 30 mA Type A RCD in one 1P+N unit, rated for 240 V AC with a 6 kA breaking capacity. The 30 mA Type A residual element catches sinusoidal AC faults plus pulsating DC faults up to 6 mA smooth DC superimposed, covering most modern electronics and single-phase drives.
Listed as active (current lifecycle stage) per Siemens, with no end-of-life notice or successor announced. RoHS compliant since June 2017;
Occupies a single 18 mm module width on DIN rail, with packaging dimensions of 90 × 18 × 80 mm. The 600 mm pigtail neutral connection simplifies panel wiring for outgoing circuits — no separate neutral bar needed downstream of the device. The B-class return restriction (Product class B) means Siemens expects the unit to be returned through authorized channel partners for warranty or compliance handling, not direct end-user return.
