Why Choose the ABB 2CDS381103R0065 Miniature Circuit Breaker?
The ABB 2CDS381103R0065, also known as the ABB S301P-B6NA, is a high-performance 1P+N miniature circuit breaker (MCB) from the ABB System pro M compact S300P series. Developed for industrial and commercial installations, it protects electrical circuits against overloads and short circuits while simultaneously switching the neutral conductor.
The S301P-B6NA combines thermal overload protection with rapid electromagnetic short-circuit tripping in a compact modular housing. An integrated trip indicator, separate contact-position indication, fail-safe terminals and a dual DIN rail release help simplify installation, inspection and maintenance.
With a 6 A rated current, a Type B tripping characteristic and a 25 kA rated short-circuit breaking capacity, the ABB 2CDS381103R0065 is particularly suitable for circuits with low starting currents, including lighting, heating, instrumentation and general control applications.
Key Advantages
- 1P+N circuit protection with simultaneous phase and neutral switching.
- 6 A rated current for low-current electrical circuits.
- Type B tripping characteristic suited to resistive loads and low inrush currents.
- 25 kA breaking capacity for demanding prospective fault levels.
- Clear trip indication supports faster fault identification.
- Compatible with ABB System pro M compact accessories.
Key Features
- ABB System pro M compact S300P series.
- S301P-B6NA miniature circuit breaker.
- 1 protected pole plus switched neutral.
- 6 A nominal current.
- Type B instantaneous tripping curve.
- Delayed thermal release for overload protection.
- Electromagnetic release for short-circuit protection.
- Supply connection possible from the top or bottom.
Responsive Protection for Low-Inrush Electrical Loads
The ABB S301P-B6NA disconnects the protected circuit when excessive current is caused by a sustained overload or short circuit. Switching the neutral conductor at the same time provides improved isolation during maintenance and helps ensure that the connected circuit is fully disconnected.
Its Type B response characteristic is intended for circuits where starting currents are relatively low. This makes the device well suited to resistive equipment, lighting, electric heating, instrumentation and control wiring while maintaining rapid operation during genuine fault conditions.
Typical Applications
- Industrial control and instrumentation circuits.
- Commercial lighting installations.
- Electric heating and resistive loads.
- PLC input and auxiliary circuits.
- Distribution boards and control panels.
- OEM machinery and monitoring equipment.
