What it is and what the ratings mean
The Siemens 5SV3652-6 is a 4-pole residual current circuit breaker (RCCB) from the SENTRON family, designed for DIN-rail mounting in distribution boards. It's an instantaneous (non-time-delayed) Type A device, meaning it detects sinusoidal AC residual currents plus pulsating DC residual currents up to 300 mA — the trip threshold. The 25 A rated current holds flat across the full ambient range from -25 °C to 70 °C (, –), so no derating headache in a warm enclosure. The 10 kA short-circuit current rating tells you it can withstand a fault up to that level without rupturing, provided the upstream protective device limits let-through energy to the listed 58 000 A²·s and peak current to 5 200 A. Rated supply voltage is 500 V AC at 50 Hz.
Panel fit and mounting
Occupies 4 modular width units (72 mm) on a 60 mm grid DIN rail. Depth is 70 mm, installation depth the same. Fastens via DIN rail (REG) and can be mounted in any position. Supply can enter from top or bottom. IP20 rating applies once installed in a distribution board with conductors connected. Overvoltage category III.
Lifecycle and sourcing
The 5SV3652-6 carries a current lifecycle status. It is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. Silicon-free construction is noted for applications sensitive to silicone outgassing.
