The Siemens 5SM3648-2 is a SENTRON selective residual current operated circuit breaker (RCCB), 4-pole, type AC, rated at 100 A with a 300 mA tripping fault current for 400 V AC 50 Hz systems. Its selective design (short-time delayed) means it coordinates with downstream RCCBs — during a ground fault, this unit stays in until the downstream device clears, keeping upstream circuits live.
Mount in any position; no derating for orientation.
The 5SM3648-2 is a selective (time-delayed) RCCB, meaning it has a deliberate delay before tripping on a ground fault. This allows a downstream RCCB to clear first, so only the faulted branch drops out — the upstream supply stays live. Standard RCCBs trip immediately.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Maximum ambient operating temperature is 45 °C; storage maximum is 75 °C.
