Why Choose the ABB S201M-D1NA Miniature Circuit Breaker?
The ABB S201M-D1NA is a compact and reliable miniature circuit breaker with switched neutral from the professional ABB System pro M compact S200M series. Designed to provide dependable overload and short circuit protection, this 1 A D curve MCB is suitable for control, auxiliary and electrical distribution circuits where phase and neutral switching is required.
The S201M-D1NA combines ABB’s current limiting technology with delayed thermal overload protection and electromechanical short circuit protection. This helps reduce fault energy during short circuit events while supporting safe and consistent protection for connected circuits and equipment.
With a 1 A rated current, D tripping characteristic, 1 protected pole plus neutral and a 10 kA breaking capacity, the ABB S201M-D1NA is ideal for circuits with higher inrush characteristics, control transformers, auxiliary supplies, signalling equipment and industrial control panels. Its DIN rail mounting format allows straightforward installation inside distribution boards, switchboards and electrical enclosures.

Reliable Protection with Switched Neutral Isolation
Miniature circuit breakers such as the ABB S201M-D1NA automatically disconnect the circuit during overload or short circuit conditions. The thermal trip element responds to sustained overloads, while the magnetic trip element provides fast disconnection during short circuit faults.
The D curve characteristic is designed for circuits with higher starting or inrush currents, making this MCB suitable for transformers, solenoids, motor control circuits and industrial equipment. The switched neutral configuration provides additional isolation by switching the neutral conductor alongside the protected phase conductor.
Typical Applications
- Industrial control panels.
- Control transformers and auxiliary supplies.
- Signalling and monitoring circuits.
- Electrical distribution boards.
- Switchboards and machine enclosures.
- Commercial and industrial installations requiring switched neutral protection.
