DS201 C10 A100 Residual Current Circuit Breaker with Overcurrent Protection

The ABB 2CSR255180R2104 is a Residual Current Circuit Breaker with Overcurrent Protection (RCBO). It is designed to provide both residual current protection and overcurrent protection in electrical installations. Here’s a basic overview of its features and specifications:

Key Features:

1. Residual Current Protection (RCD):
   The device provides protection against earth fault currents, which can occur when there is leakage to the ground. It detects the imbalance between the live (phase) and neutral conductors, ensuring the safety of the electrical circuit and reducing the risk of electrical shock.
2. Overcurrent Protection:
   It also provides protection against overload and short-circuit currents, ensuring the circuit is not damaged due to excessive current flow.
3. One Device for Multiple Protections:
   The 2CSR255180R2104 combines both residual current protection and overcurrent protection in a single unit, making it ideal for protecting both people and electrical equipment in residential, commercial, and industrial applications.
4. Type A:
   It is typically classified as a Type A device, meaning it is suitable for use with both sinusoidal alternating currents (AC) and pulsating direct currents (DC) caused by modern electronic devices.
5. Current Rating:
   The device has specific current ratings for both residual current and overcurrent protection, typically ranging from 10A to 40A, depending on the model.
6. Safety Features:
   • Fault current protection: Protects users from electric shocks caused by indirect contacts.
   • Overload and short-circuit protection: Ensures that circuits are not damaged by excessive current flow.
   • Manual reset: Allows for resetting after the protection has been triggered.

Applications:

• Residential: Protects homes and apartments against electrical faults and overloads.
• Commercial and Industrial: Provides safety for office buildings, factories, and warehouses where electrical systems are subject to higher loads and more complex fault conditions.

Technical Specifications:

• Poles: 2-pole (1P+N), for single-phase applications.
• Rated Current: Typically between 10A and 40A (depending on the exact model variant).
• Rated Residual Operating Current: Usually 30mA, to ensure the protection of people from electric shocks.
• Tripping Characteristics: It trips instantly in the event of a fault, with no delay for earth leakage protection.

Benefits:

• Compact Design: Saves space in the distribution board, offering reliable protection in a small package.
• Increased Safety: Provides dual protection—against earth faults and overcurrent—ensuring complete electrical safety.
• Compliance with Standards: Meets international standards for electrical safety, offering peace of mind to users and installers alike.

This model is ideal for ensuring the safety of electrical installations by providing comprehensive protection for circuits and individuals against both leakage currents and overload conditions.
