🎨 Design & Style
Type: Modular Residual Current Circuit Breaker (RCCB). Its primary function is to protect the electrical installation from fire risk and indirect contact in the event of a significant leakage current.
Appearance: Standard, four-pole device in a compact insulating housing, designed for installation in electrical distribution boards.
Operation: Features an operating lever and a "Test" button for routine functional checks.
📏 Dimensions & Installation
Width: 4 Modules (4M) — standard width for three-phase devices, optimized for panel installation.
Installation: Designed for quick and secure mounting on a standard DIN rail.
Application: Used as a main breaker or at the inlet of three-phase installations (380V/400V) in industrial, commercial, or large residential buildings where system protection against leakage is required.
⚙ Technical Specifications
Poles: 4P (Four-pole) — for three-phase networks (3 phases + neutral).
Rated Current (In): 63 A.
Sensitivity (IΔn): 300 mA (milliamperes) — suitable for fire protection and indirect contact protection (according to IEC 60364), but not for direct human protection.
Current Type: AC-TYPE — detects sinusoidal alternating residual currents.
Rated Voltage (Ue): 400V AC (three-phase), 50/60 Hz.
Standards: Compliant with European and international standards (e.g., EN/IEC 61008-1).
✅ Advantages
Installation Protection: Effective protection of the entire three-phase installation from damage and overheating that could lead to fire.
Three-Phase Application: Provides simultaneous interruption of all three phases and the neutral conductor.
Reliability: Instantaneous power interruption upon detection of a leakage current.
