Key Features:

• 300 mA Sensitivity
  Designed primarily for fire protection by detecting higher levels of earth leakage current that could lead to overheating and electrical fires.

• Class AC Response
  Detects standard sinusoidal AC residual currents – suitable for most general applications that do not involve electronic loads.

• Add-On Design
  Easily mounts onto C120 2P MCBs, converting them into RCBO-like devices for combined overload, short-circuit, and earth leakage protection.

• Enhanced Installation Safety
  Enables detection of leakage currents that may not trip regular circuit breakers, adding a layer of preventive safety.

• Modular and Space-Efficient
  Fits into existing distribution boards without major layout changes.

• Reliable Operation
  Built for consistent performance and long life, even in demanding environments.

Applications:

• Fire Protection Circuits
  Ideal for circuits where fault detection is required to prevent fire risks due to persistent leakage currents.

• Industrial Distribution Panels
  Adds leakage protection to motor circuits, lighting, and power distribution boards.

• Non-Residential Buildings
  Suitable for warehouses, commercial buildings, and workshops.

• Equipment Protection
  Prevents undetected ground faults that could damage sensitive or high-value equipment.

• Retrofit Upgrades
  A convenient solution for upgrading existing installations to meet enhanced safety standards.
