ABB S204-C40 · thermal-magnetic 4P breaker
Exact reference · S204-C40
Protects the selected circuit against overload and short circuit. The current rating and trip curve must suit the load, conductors and installation.
- Protection function
- Thermal-magnetic overload and short-circuit protection
- Poles
- 4
- Neutral protection
- 4 protected poles · neutral at 100%
No integrated residual-current protection. Use separately selected earth-leakage protection where required. Four protected and jointly switched poles for L1, L2, L3 and N. The neutral has full-current protection, not merely a switched 3P+N pole. Protective earth must remain outside the switched path.

01 · Product role
What this product does in the system.
Protects the selected circuit against overload and short circuit. The current rating and trip curve must suit the load, conductors and installation.
Relevant applications
- Selected commercial distribution with L1, L2, L3 and N.
Why ReneWave may shortlist it
- Protects the selected circuit against overload and short circuit. The current rating and trip curve must suit the load, conductors and installation.
System position
Four-pole commercial distribution: L1, L2, L3 and N.
No integrated residual-current protection. Use separately selected earth-leakage protection where required. Four protected and jointly switched poles for L1, L2, L3 and N. The neutral has full-current protection, not merely a switched 3P+N pole. Protective earth must remain outside the switched path.
The closed four-pole device supplies L1, L2, L3 and N to commercial distribution. Protective earth bypasses the device and is never switched. Branch devices are separate, not included.
Read the technical explanation
No integrated residual-current protection. Use separately selected earth-leakage protection where required. Four protected and jointly switched poles for L1, L2, L3 and N. The neutral has full-current protection, not merely a switched 3P+N pole. Protective earth must remain outside the switched path.

03 · Selection points
Four practical selection points.
Match the device to the circuit, expected load and fault conditions. Request a quote for the exact reference you have selected.
- 01
Pole configuration
Four protected and jointly switched poles for L1, L2, L3 and N. The neutral has full-current protection, not merely a switched 3P+N pole. Protective earth must remain outside the switched path.
- 02
Current and trip function
Protects the selected circuit against overload and short circuit. The current rating and trip curve must suit the load, conductors and installation.
- 03
Voltage and fault capacity
Compare the prospective fault current with the capacity at the actual supply voltage and standard. Icn, Icu and Ics are different ratings, not interchangeable labels.
- 04
Mounting and connections
DIN TH35 mounting. Match the conductor type and cross-section to ABB’s terminal limits; use the documented stripping length and tightening torque. Never route protective earth through the breaker.
