The Siemens 5SV9316-7PK40 is a 1P+N RCBO (residual current circuit breaker with overcurrent protection) rated at 40 A, 240 V AC, with a 6 kA breaking capacity. It combines Type A residual current protection at 30 mA with a C-curve overcurrent characteristic, making it suitable for final circuits in residential and commercial distribution boards where both earth leakage and overload/short-circuit protection are required in a single module.
Packaged singly, dimensions 90 x 18 x 80 mm — the 18 mm width occupies one standard DIN-rail module position in a distribution board. The 600 mm pigtail simplifies wiring to the neutral busbar in a panel layout. Product class B indicates return restrictions; coordinate with your Siemens channel partner for any warranty or replacement claims.
