The Siemens 5SV5616-0 is a 2-pole residual current operated circuit breaker (RCCB) from the SENTRON family, rated 63 A at 230 V AC with a 300 mA residual trip threshold, Type AC (sinusoidal AC fault currents only). It is an instantaneous-trip device (no intentional short-time delay), so it clears ground faults within one cycle — the right choice for general-purpose socket circuits and lighting where nuisance tripping from transient surges is not a concern. The 6 kA short-circuit current rating (SCCR) per EN 60898 and IEC 61008-1 means the device safely interrupts a fault up to that level without rupturing — adequate for most residential and light commercial distribution boards where the prospective fault current stays under 6 kA.
Rated 63 A at 40 °C ambient, with a permissible I²t of 110 000 A²·s for through-fault energy let-through — useful for coordinating with downstream MCBs and ensuring the RCCB withstands the thermal stress of a bolted fault before the upstream device clears. Operating temperature range is -25 °C to +45 °C; storage range extends from -40 °C to +75 °C, so the device can be warehoused in unconditioned spaces but must be commissioned within the narrower operating band. Overvoltage category III — suitable for fixed-installation distribution boards where transient overvoltages from the utility side are expected.
Silicon-free construction matters for automotive paint-shop or semiconductor-fab installations where silicone outgassing can contaminate surfaces; the 5SV5616-0 carries that designation.
