For all-round protection from electrical faults, clip this RCBO from ABB onto your DIN rail. It combines four modules to protect against short circuits, overload and earth fault currents, as well as direct and indirect contacts. That means you can trust it to keep people safe from shocks and equipment free from electrical damage. A voltage rating of 415V AC and a 3P+N terminal configuration mean it's well-placed to protect 3-phase systems. The type C characteristic ensures it trips when it detects currents between five and 10 times the 16A rated load. The unit works instantly to stop surges in their tracks.

• Wide operating temperature range between -25°C and +55°C, to handle demanding environments
• Accepts busbar and flexible wire connections for versatility
• Modular design makes it a cinch to expand your safety system
• Button on the front for easy function testing

• Public spaces
• Power distribution boards
• Industrial plants

The ABB DS203NC is a 3P+N residual current circuit breaker with overcurrent protection in four modules for the protection against short-circuit currents, overload, earth fault currents, indirect contacts and additional protection against direct contacts. The rated current of this RCBO is the 16 A.

Ambient air temperature for operation is -25 to 55 °
Din rail mounting

Yes. An electrical lifespan of 10,000 cycles and a mechanical lifespan of 20,000 cycles mean this RCBO is a durable choice.
