Why Choose the ABB SH201-D40 Miniature Circuit Breaker?
The ABB SH201-D40 is a compact single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the ABB Compact Home SH200 range, it combines thermal overload protection with electromagnetic short-circuit protection in a space-efficient DIN-rail device.
Featuring a Type D tripping characteristic, the SH201-D40 is intended for appropriately designed circuits where comparatively high starting or inrush currents can occur during normal operation. Type D behaviour makes the breaker suitable for selected inductive and high-inrush loads where the circuit design requires greater tolerance of short-duration starting currents.
With a rated current of 40 A and a rated short-circuit capacity of 6 kA, the SH201-D40 provides dependable overcurrent protection for suitable higher-current final and equipment circuits. Its compact single-module construction helps conserve distribution-board space, while ABB order code 2CDS211001R0401 identifies this specific 40 A Type D model.
Key Advantages
- Reliable overload and short-circuit protection for suitably rated electrical circuits.
- 40 A rated current for appropriately designed higher-current circuits.
- Type D tripping characteristic accommodates comparatively high normal starting and inrush currents.
- Single-pole configuration provides overcurrent protection for one conductor.
- 6 kA rated short-circuit capacity for dependable fault protection.
- Compact single-module design helps conserve DIN-rail space.
Key Features
- ABB Compact Home SH200 series.
- 40 A rated current.
- 1P configuration with one protected pole.
- Type D tripping characteristic.
- Thermal tripping mechanism for overload protection.
- Electromagnetic tripping mechanism for short-circuit protection.
- 6 kA rated short-circuit capacity.
- Current-limiting miniature circuit breaker design.
- DIN-rail mounting for installation in compatible distribution equipment.
Type D Protection for Higher-Inrush Loads
The ABB SH201-D40 uses complementary thermal and electromagnetic tripping mechanisms to protect electrical circuits. Its thermal mechanism responds to sustained overload currents, while the electromagnetic mechanism provides rapid disconnection under short-circuit conditions, helping protect conductors and connected equipment from damaging overcurrents.
Its Type D characteristic is intended for appropriately engineered circuits where connected equipment can produce comparatively high switch-on currents during normal operation. Combined with a 40 A rating and 6 kA short-circuit capacity, the SH201-D40 provides compact protection where both higher load current and tolerance of normal inrush current are required.
Typical Applications
- Residential and building-services electrical installations where Type D protection is specified.
- Circuits supplying equipment with comparatively high normal starting currents.
- Suitable transformer and inductive-load circuits.
- Equipment circuits requiring a 40 A protective device.
- Distribution circuits where Type D tripping characteristics are appropriate.
- Compact distribution boards where DIN-rail space is limited.
- Applications specifically requiring a 40 A Type D miniature circuit breaker.
