The Siemens SENTRON 5SV3616-3 is a 2-pole residual current circuit breaker (RCCB) rated 63 A with a 300 mA trip threshold, Type F characteristic for circuits that carry mixed-frequency residuals from VFDs or washing machine drives. It is short-time delayed, so it coordinates with surge arrestors and avoids nuisance tripping on transient ground faults.
What the ratings mean for fit
The 63 A rating holds flat from 40 °C up to 60 °C (–), only derating to 56.96 A at 65 °C and 48.2 A at 70 °C (–). That means in a warm enclosure you still get full rated current through most normal panel ambient conditions. The 300 mA residual trip is not for personnel protection — that is the 30 mA class — but for equipment or fire protection on circuits where some leakage is expected. Type F handles smooth DC and mixed-frequency AC residuals up to 1 kHz, which is the right pick for single-phase VFDs, heat pumps, and EV chargers.
Breaking capacity and selectivity
The 5SV3616-3 carries a 10 kA short-circuit current rating (SCCR) per IEC 61008-1 and a conditional rated short-circuit current of 0.8 kA per EN 60898 and IEC 61008-1. The 10 kA figure is the withstand when backed by an upstream overcurrent device; the 0.8 kA is the standalone breaking capacity under the RCCB standard. The short-time delayed design lets it ride through downstream MCB clearing without dropping the whole submain — useful for selective coordination in a distribution board.
Panel integration and environment
Snap-on DIN rail mount, 2 MW width, 36 mm wide × 90 mm high × 70 mm deep. Installs in any orientation. Supply feed top or bottom. Rated IP20 with conductors connected inside a distribution board — so it is an enclosed-panel part, not for standalone wet-area use. Silicon-free construction is noted for applications that must avoid silicone outgassing, like paint shops or electronics potting lines. Operating ambient -25 °C to 45 °C; storage -40 °C to 75 °C.
Lifecycle and sourcing
Listed as current production. This is not an NRND or obsolete line; the 5SV3616-3 is an active catalog item in the SENTRON RCCB family. Sourced and quoted to order against an RFQ through independent distribution — availability and current pricing confirmed at quote time.
