Why Choose the ABB SN201M-B6 Miniature Circuit Breaker?
The ABB SN201M-B6 is a compact 1P+NP miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits while providing simultaneous switching of the phase and neutral conductors. It provides practical circuit protection for residential, commercial and industrial distribution applications.
Featuring a Type B tripping characteristic, the SN201M-B6 is suited to circuits with relatively low starting and inrush currents. This makes it suitable for applications such as lighting, resistive loads, control circuits and other general-purpose electrical equipment.
With a rated current of 6 A, a 1P+NP configuration and a 10 kA short-circuit breaking capacity, the SN201M-B6 combines overcurrent protection and neutral switching in a compact DIN-rail device. The protected phase pole incorporates thermal and electromagnetic tripping, while the neutral pole is switched together with the phase.
Key Advantages
- Reliable overload and short-circuit protection.
- 6 A rated current for low-current branch and final circuits.
- 1P+NP configuration combines a protected phase pole with a switched neutral pole.
- Type B tripping characteristic suited to circuits with relatively low inrush currents.
- 10 kA short-circuit breaking capacity.
- Compact DIN-rail mounting for distribution and control panels.
Key Features
- ABB SN201M series.
- 6 A rated current.
- 1P+NP pole configuration.
- Type B tripping characteristic.
- 10 kA breaking capacity.
- Protected phase conductor with switched neutral conductor.
- Thermal tripping mechanism for overload protection.
- Electromagnetic tripping mechanism for rapid short-circuit protection.
Compact Phase and Neutral Circuit Protection
The ABB SN201M-B6 automatically disconnects the protected phase conductor when an overload or short-circuit condition occurs. Thermal operation responds to sustained overloads, while electromagnetic operation provides rapid disconnection during short-circuit faults.
The 1P+NP arrangement combines overcurrent protection of the phase conductor with simultaneous switching of the neutral conductor. Its Type B characteristic makes the SN201M-B6 well suited to lighting, resistive loads, control equipment and other circuits without substantial normal inrush currents.
Typical Applications
- Low-current branch and final circuits.
- Lighting circuits.
- Resistive electrical loads.
- Industrial control and automation circuits.
- Commercial and residential electrical installations.
- DIN-rail distribution and control panels.
