ETAON ERB6-25/1/C/03 Central control module

Product Detailed Description

• Functionality:

• Overcurrent Protection (MCB): Detects and trips on overloads and short-circuits to protect electrical circuits and equipment from damage. The "C" characteristic indicates it's suitable for general applications where inrush currents are moderate (e.g., residential, commercial, and light industrial loads).

• Residual Current Protection (RCD/RCCB): Detects small leakage currents to earth (ground faults) which can cause electric shock. The "0.03 A" (30 mA) fault current rating is a typical sensitivity for direct human protection.

• Combined Device: Offers both forms of protection in a single compact unit, saving space in distribution boards.

• Key Features:

• Single-pole (1P) + Switched Neutral (or 1+N): This specific model is a single-pole device with a switched neutral. This means it provides overcurrent protection on one phase and residual current protection across both phase and neutral, ensuring that the neutral conductor is also disconnected when a fault occurs.

• Compact Design: Often designed with a narrow width (e.g., 1 modular spacing) to maximize space efficiency in consumer units or distribution boards.

• Electronic RCD: Utilizes electronic tripping for residual current detection.

• High Quality Standards: Manufactured by Eaton (formerly Moeller), known for reliable circuit protection products.

• Easy Installation: Designed for standard DIN rail mounting.

• Test Button: Includes a test button for regular functional checks of the RCD part.

Product Advantages

• Enhanced Safety: Provides dual protection against overcurrents and dangerous earth leakage currents, significantly improving safety for individuals and preventing fire hazards.

• Space-Saving: Combines MCB and RCD functions into a single compact unit, reducing the space required in distribution boards.

• Reliability: Eaton's reputation for high-quality circuit protection ensures reliable operation and long service life.

• Ease of Installation: Designed for quick and secure mounting on standard DIN rails.

• Broad Application Range: "C" characteristic is suitable for a wide variety of loads in residential, commercial, and light industrial settings.

• Regulatory Compliance: Meets relevant international safety standards (e.g., EN 61009, IEC 60947-2).

• Clear Indication: Often features a window or indicator for fault conditions (e.g., tripped state).

Precautions

• Correct Selection: Always ensure the RCBO's rated current, trip characteristic, fault current rating, and voltage match the specific circuit and load requirements. Incorrect selection can lead to nuisance tripping or insufficient protection.

• Professional Installation: Installation must be carried out by qualified personnel in accordance with national and local wiring regulations (e.g., IEC 60364).

• Proper Wiring: Ensure all connections are secure and tightened to the specified torque. Use appropriate conductor sizes.

• Earthing/Grounding: Proper earthing of the electrical installation is crucial for the effective operation of the RCD function.

• Regular Testing: The test button on the RCBO should be operated regularly (e.g., monthly) to ensure the residual current protection mechanism is functioning correctly.

• Environmental Conditions: Operate the device within the specified ambient temperature and humidity ranges. Protect it from direct sunlight, excessive dust, and moisture.

• Voltage Type: This specific model is for AC circuits. Do not use it for DC circuits unless specified.

• Surge Protection: While the RCBO offers some surge current capacity, additional surge protective devices (SPDs) may be necessary for comprehensive protection against lightning and other transient overvoltages, especially in sensitive applications.

Product Applications

The Eaton xPole - eRB6/M RCBO, including the ERB6-25/1/C/03, is widely used in various electrical installations where combined overcurrent and earth leakage protection is required. Common applications include:

• Residential Buildings: Protecting individual circuits for sockets, lighting, and appliances.

• Commercial Buildings: Offices, shops, schools, and hospitals to protect final circuits and ensure personnel safety.

• Light Industrial Applications: Workshops, small factories, and machinery requiring integrated protection.

• Special Circuits: Circuits supplying equipment in kitchens, bathrooms, outdoor sockets, and areas with increased risk of electric shock.

• HVAC Systems: Protection for air conditioning units and heating systems.

• Data Processing: Protection for circuits supplying IT equipment (though Type A or F RCDs might be preferred for specific electronic loads).
