Key features and benefits:

1. Enhanced residual current protection: The Eaton residual current circuit breaker with a 100 mA residual current rating offers extended protection for installations where even low residual currents can be dangerous. This is particularly important for protecting people and preventing damaging surges in electrical current .
   
2. Pulse current sensitivity: The switch is capable of detecting pulsating fault currents , which typically occur in modern devices such as inverters and solar power systems . This makes the Eaton residual current circuit breaker particularly suitable for applications with digital electronics .
   
3. Selective disconnection: The Type A residual current circuit breaker offers selective disconnection in the event of a fault. This means that it only disconnects the affected circuit, leaving the rest of the electrical installation intact, thus reducing downtime and optimizing operation.
   
4. Surge current resistance: The switch is surge current resistant up to 250 A , which makes it particularly resistant to sudden voltage spikes caused by lightning strikes or other transient disturbances.
   
5. Easy installation: The Eaton residual current circuit breaker (RCCB) can be quickly and easily mounted on a DIN rail . With a width of 4 modules (70 mm), it fits into all standard distribution boxes and control cabinets , simplifying integration and replacement in existing installation systems.
   
6. Robust and versatile connection options: The clamping cross-section of 1.5–35 mm² for solid cables and 2 x 16 mm² for stranded cables ensures high flexibility during installation, so that even larger cable cross-sections can be connected without any problems.
   

Areas of application:

• Residential buildings: The Eaton residual current circuit breaker (RCCB) is ideally suited for protecting homes and apartment buildings . By protecting against residual currents, the breaker offers a high level of safety for residents and the electrical infrastructure.
  
• Commercial and industrial buildings: Especially in offices , workshops and business premises , the residual current circuit breaker (RCCB) ensures a reliable power supply and protects both people and equipment from electrical hazards.
  
• Industry: The Eaton residual current circuit breaker is also suitable for use in industrial environments, as it reliably detects pulsating fault currents and ensures safe disconnection.
