ABB DSE201 M 1P+N RCBO 10A 100mA
The DSE201 M C10 AC100 is a 1P+N electronic residual current circuit breaker with overcurrent protection (RCBO) in a compact one-module width, combining overload and short-circuit protection with residual current protection against earth fault currents in a single device. Featuring Type AC sensitivity for sinusoidal alternating earth fault currents and Type C tripping for overload protection, it is designed for single-phase end-user circuits in residential and commercial UAE distribution boards where combined overcurrent and earth leakage protection is required in minimal panel space.
Key Features
- Combined overcurrent and residual current protection in a single 1-module-wide device, saving distribution board space
- 10A Type C overcurrent protection paired with 100mA Type AC residual current sensitivity
- Protection against indirect contacts and additional protection against direct contacts
- Unswitched neutral with flying lead connections for neutral and functional earth, simplifying installation
- Genuine ABB quality

Applications
- Combined overcurrent and earth leakage protection for single-phase end-user circuits
- Residential distribution boards requiring compact, space-saving RCBO protection
- Commercial circuit protection where indirect and direct contact protection is required
- Retrofit upgrade from separate MCB and RCCB to a single combined device in UAE installations
FAQ
-
What is an RCBO, and how is it different from an MCB or RCCB?
An RCBO (Residual Current Breaker with Overcurrent protection) combines an MCB and an RCCB in one device — it protects a single circuit against both overload/short-circuit and earth leakage, instead of needing separate devices.
-
What does the 100mA sensitivity rating mean?
100mA RCBOs are sized for fire and equipment protection rather than personal shock protection, which requires 30mA.
-
Why use an RCBO instead of a shared RCCB for multiple circuits?
An RCBO protects one circuit only, so a leakage fault on that circuit trips just that RCBO rather than a shared RCCB covering several circuits — this avoids losing power to unaffected circuits when a fault occurs on one.
-
Can I install this myself?
No. RCBOs are wired into a live distribution board and must be installed by a licensed electrician in line with UAE wiring regulations.
