RCCB 40 A

Dimensions:

Looking for comprehensive and reliable protection against electric shock for three-phase systems in your home, office, or workshop? The four-pole (4P) RCCB / RCD Type AC with a high sensitivity of 0.03 A (30 mA), available in 25 A, 40 A, and 63 A models with a short-circuit capacity of 6000 A (6 kA), delivers maximum safety for your entire three-phase electrical installation.

Designed for flawless operation and instant reaction to the slightest earth leakage currents, this residual current circuit breaker safeguards human lives and sensitive three-phase systems from dangerous electrical faults.

Why Choose a 4-Pole 30 mA RCCB (Type AC, 6 kA)?

• Life-Saving 30 mA (0.03 A) Sensitivity: The gold standard for direct personal protection against electric shock. It trips in a fraction of a second upon direct contact with live parts or insulation failure in equipment (e.g., three-phase ovens, heat pumps, electric motors, workshop power tools).
• Complete Three-Phase Coverage (4-Pole Design): Simultaneously monitors all three phases (L1, L2, L3) and the neutral conductor (N), ensuring complete and uniform protection for all three-phase and single-phase loads connected to the system.
• 40 A: The standard choice for residential homes, apartments, and modern commercial spaces with a three-phase connection.
• 6000 A (6 kA) Short-Circuit Capacity: Provides high durability and stability for internal mechanisms during heavy grid short-circuit events, preventing damage to the breaker and connected wiring.
• Type AC: Reliably detects sinusoidal AC residual currents, making it a proven choice for standard three-phase installations and conventional loads.

Key Advantages & Quality Features

• Uncompromised Safety for Life and Property: Instantly interrupts the circuit upon detecting hazardous leakage currents, preventing severe injuries and electric shock hazards.
• Complete Four-Pole Isolation: Simultaneously disconnects all three phases and the neutral conductor upon fault detection, offering full system isolation for maximum maintenance safety.
• Premium Build Quality: Features a high-density, self-extinguishing housing resistant to thermal strain and impacts, ensuring a long operational life under continuous load.
• Integrated TEST Button: Enables quick and easy periodic testing of the internal tripping mechanism without needing specialized tools.
• Simple DIN-Rail Mounting (4 Modules): Standardized footprint designed for quick, secure installation on DIN rails in all standard distribution panels.
• The possibility of connecting to a pin and fork bus
• Window for labeling, inscription
• Color status indicator
