Why Choose the ABB SH201-C20NA Miniature Circuit Breaker?
The ABB SH201-C20NA is a compact and reliable miniature circuit breaker (MCB) designed to provide overload and short-circuit protection in residential and similar low-voltage electrical installations. As part of the ABB Compact Home SH200 series, it combines a 1P+N configuration, C tripping characteristic and 20 A rated current in a convenient DIN rail-mounted format.
This current-limiting circuit breaker uses two complementary tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short-circuit protection. The SH200 series is designed for straightforward integration into modular distribution boards and complies with IEC/EN 60898-1 for residential circuit-protection applications.
With a rated current of 20 A, a Type C tripping characteristic and a rated short-circuit capacity of 6 kA at 230 V AC, the SH201-C20NA is suitable for protecting appropriately rated low-voltage final circuits. Its 1P+N arrangement provides one protected pole together with a concurrently switched neutral in a compact two-module device.
Key Advantages
- Reliable overload and short-circuit protection for low-voltage circuits.
- 20 A rated current for appropriately rated final circuits.
- Type C tripping characteristic suitable for general-purpose loads with moderate inrush currents.
- 6 kA short-circuit breaking capacity at 230 V AC according to IEC/EN 60898-1.
- 1P+N configuration combines phase protection with switched neutral functionality.
- Compact two-module construction for modular distribution boards.
Key Features

Reliable Protection for Low-Voltage Circuits
Miniature circuit breakers such as the ABB SH201-C20NA automatically disconnect a circuit when excessive current is detected. The delayed thermal tripping mechanism responds to sustained overload conditions, while the electromechanical mechanism provides rapid operation when a short circuit occurs.
The Type C characteristic is suited to many general-purpose circuits and loads that can produce moderate starting currents. Combined with the SH200 series' current-limiting design and 1P+N configuration, the SH201-C20NA provides practical and dependable circuit protection for modern modular electrical distribution systems.
Typical Applications
- Residential electrical distribution boards.
- Lighting and appropriately rated final circuits.
- General-purpose building electrical circuits.
- Circuits supplying loads with moderate starting currents.
- Small commercial distribution systems.
- DIN rail-mounted consumer units and distribution enclosures.
