Why Choose the ABB SH201-D20 Miniature Circuit Breaker?
The ABB SH201-D20 is a compact and reliable single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. As part of the ABB System pro M compact SH200 range, it provides dependable circuit protection for residential, commercial and similar electrical installations.
This miniature circuit breaker uses a Type D tripping characteristic, making it particularly suitable for circuits supplying loads with high starting or inrush currents. Its thermal overload and electromagnetic short-circuit protection help safeguard conductors and connected equipment while accommodating normal transient currents associated with suitable inductive and high-inrush loads.
With a rated current of 20 A, a single-pole configuration and a rated short-circuit capacity of 6 kA, the SH201-D20 provides robust protection in a compact format. Its 17.5 mm single-module construction and DIN rail mounting allow straightforward integration into consumer units and modular distribution boards.
Key Advantages
- Reliable overload and short-circuit protection for electrical circuits.
- 20 A rated current for branch and final circuit protection.
- Type D tripping characteristic suitable for loads with high starting or inrush currents.
- 6 kA rated short-circuit capacity.
- Compact single-pole construction occupies one 17.5 mm DIN rail module.
- Suitable for circuits where normal start-up currents require a Type D tripping characteristic.

Reliable Protection for High-Inrush Circuits
Miniature circuit breakers such as the ABB SH201-D20 automatically interrupt a circuit when excessive current occurs because of an overload or short circuit. Thermal protection responds to sustained overload conditions, while electromagnetic operation provides rapid interruption when a sufficiently high short-circuit fault current occurs.
The Type D characteristic is intended for circuits supplying loads that can draw substantial transient current during start-up. Combined with its 20 A rating and 6 kA short-circuit capacity, the SH201-D20 provides a practical protection solution for suitable high-inrush applications while retaining a compact single-module footprint.
Typical Applications
- Residential and commercial electrical distribution.
- Circuits with high starting or inrush currents.
- Suitable transformer supply circuits.
- Discharge-lighting circuits.
- Inductive and high-inrush electrical loads.
- Consumer units and modular distribution boards.
