2CSS255101R0065 ABB SN201-B6 Miniature Circuit Breaker 6 A 1P+NP Type B 6 kA

Why Choose the ABB SN201-B6 Miniature Circuit Breaker?

The ABB SN201-B6 is a compact 1P+NP miniature circuit breaker (MCB) designed to provide overload and short-circuit protection in electrical distribution, control and equipment circuits. Part of ABB's modular circuit-protection portfolio, it combines a 6 A rated current with a Type B tripping characteristic for circuits where relatively low temporary inrush currents are expected.

The SN201-B6 uses thermal-magnetic protection to automatically disconnect the protected circuit under sustained overload or short-circuit conditions. Its Type B characteristic provides responsive instantaneous protection, making it suitable for appropriately designed resistive, control and general electrical loads that do not normally produce substantial starting-current peaks.

With its 1P+NP configuration, 6 A rated current and 6 kA breaking capacity, the SN201-B6 provides dependable circuit protection in a compact DIN-rail-mounted format. Its switched neutral pole configuration makes it suitable for appropriately designed single-phase circuits requiring simultaneous switching of phase and neutral.

Key Advantages

• Compact 1P+NP miniature circuit breaker for single-phase circuit protection.
• 6 A rated current for appropriately rated electrical circuits.
• Type B tripping characteristic suited to circuits with relatively low inrush currents.
• Provides overload and short-circuit protection on the protected pole.
• 6 kA breaking capacity for dependable fault interruption.
• Switched neutral pole enables simultaneous phase and neutral disconnection.
• DIN-rail-mounted construction for efficient installation in modular electrical panels.

Key Features

• ABB SN201 series.
• 1P+NP configuration with protected phase and switched neutral pole.
• 6 A rated current.
• Type B tripping characteristic.
• Thermal-magnetic protection against overload and short-circuit conditions.

Reliable Protection for Low-Inrush Circuits

Miniature circuit breakers such as the ABB SN201-B6 protect electrical wiring and connected equipment by interrupting excessive current. The thermal element responds to sustained overload conditions, while the magnetic mechanism provides rapid operation during short-circuit faults.

The Type B characteristic is intended for circuits where substantial temporary starting currents are not normally expected. Combined with its 1P+NP arrangement, the SN201-B6 provides overcurrent protection for the phase conductor while also switching the neutral pole, supporting compact single-phase distribution and equipment-panel designs.

Typical Applications

• Single-phase electrical distribution circuits.
• Industrial control and automation panels.
• Control and auxiliary circuits.
• Resistive and relatively low-inrush electrical loads.
• Circuits requiring phase protection with switched neutral disconnection.
• OEM electrical assemblies and machine building.
