Description

The FuseBox Mini RCBO (Residual Current Circuit Breaker with Overload Protection) RTAM Series is a compact, space-saving device for the provision of combined earth leakage and overcurrent protection in electrical installations. Type A RCBOs detect AC and pulsating DC leakage currents and are suitable for new installations with electronics and equipment that may produce DC leakage.  

As it is a B-Curve type, the RTAM series is fit for general residential and commercial use, offering protection to lighting, socket outlets, and other general circuits. Its rated currents in the series are available from 6A to 40A, which makes it highly versatile for different load conditions.

• Current Rating: Higher-rated devices (32A, 40A) suit higher load or dedicated equipment, while lower-rated units (6A–20A) suit lighting and general-purpose outlets.

• Trip Characteristics: All use a B-Curve, making them ideal for general domestic and light commercial installations.

• Earth Fault Sensitivity: All rated at 30mA for personal protection.

• Applications:

  • 6A–16A: Ideal for lighting and smaller radial or dedicated appliance circuits.

  • 20A–40A: Suitable for higher load rings, appliance circuits, or dedicated equipment connections (such as electric vehicle charging or heating).

Key Features

• Type A Protection: Sensitive to AC and pulsating DC residual currents, ideal for EV chargers, solar installations, and equipment with switched-mode electronics.

• B-Curve Tripping Characteristics: Operate within 3–5 times the rated current, making it ideal for resistive or low inrush applications (lighting, general socket circuits).

• Compact Design: Single module design allows for efficient use of consumer unit space.

• High Breaking Capacity: Rated for 6kA, ensuring reliability under fault conditions.

• Integrated Neutral and Earth Fault Protection.

• Lockable Toggle Switch for enhanced safety during maintenance.

• Rated Voltages: 230V AC

• Compliance: EN 61009-1 and IEC 61009-1 standards.
