ABB S801S-C40, S800S series miniature circuit breaker, 1-pole, Trip Curve C, 40 A, 230 VAC, 50 kA interrupting rating, DIN rail mount.
| Parameter | Value |
|---|---|
| Amps | 40 |
| Type | Trip Curve C |
| Poles | 1 |
| Mounting | DIN Rail |
| Volts AC | 230 |
| Breaking capacity | 50 kA |
The interrupting rating of 50 kA at 230 VAC means this breaker can safely clear a fault current up to 50,000 A without welding or rupturing — critical for high-fault-capacity installations where standard 10 kA MCBs would fail.
The single-pole footprint occupies one module width (17.5 mm typical for S800S), leaving adjacent slots for additional poles or other DIN-rail components.
The S801S-C40 is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
The S801S-C40 is rated 40 A continuous current.
The S801S-C40 uses Trip Curve C, which trips magnetically between 5 and 10 times the rated current — suited for general-purpose distribution.
No — the S801S-C40 is a 1-pole breaker, while the S204-C32 is a 4-pole unit. The pole count difference means a direct drop-in is not possible without rewiring the circuit.
