ABB DSE201 M 1P+N RCBO 20A 30mA

ABB DSE201 M 1P+N RCBO 20A 30mA

The DSE201 M C20 AC30 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 high-sensitivity residual current protection in a single device. With a 30mA Type AC sensitivity, it provides additional protection against direct contacts as well as protection against indirect contacts, making it well suited to end-user single-phase circuits in UAE residential and commercial distribution boards where personnel safety is a priority.

Key Features

• Combined overcurrent and residual current protection in a single 1-module-wide device, saving distribution board space
• 20A Type C overcurrent protection paired with 30mA Type AC residual current sensitivity for personnel protection
• Additional protection against direct contacts as well as protection against indirect contacts
• Unswitched neutral with flying lead connections for neutral and functional earth, simplifying installation
• Genuine ABB quality

Technical Specifications

Applications

• Personnel protection circuits requiring 30mA sensitivity in residential and commercial installations
• Bathroom, kitchen, and outdoor socket circuit protection in UAE villas and apartments
• Combined overcurrent and earth leakage protection where direct contact safety is required
• Retrofit upgrade from separate MCB and RCCB to a single combined device in distribution boards

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 30mA sensitivity rating mean?
  30mA RCBOs are sized for personnel/shock protection on final circuits.
• 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.
