Description

A residual current-operated circuit breaker with overcurrent protection (RCBO). Combines functions of overload, short circuit protection, and earth fault detection in one unit. Trips immediately when leakage current exceeds 30mA or if the line draws more than 20 Amps. Ensures safety for electrical systems by disconnecting circuits during faults. ### Electrical Ratings Rated operational voltage: 400V AC, suitable for three-phase neutral configurations. Current rating: 20A with B-type tripping characteristic — sensitive to moderate inrush currents typical of most inductive loads. Earth leakage sensitivity set at a threshold of 30mA supporting Type A operation — detects both AC and pulsating DC components up to specific frequency ranges. ### Physical Properties & Standards Compliance Three-pole plus neutral design accommodating quad-terminal connections. DIN rail-compatible mounting setup - compatible with standard distribution boards. Constructed under IEC standard compliance (IEC/EN 61009), ensuring reliability across varied environments. - For installations requiring precise overload cutoff and earth leakage detection only. - Not rated for systems exceeding 440V usage. - Operating temperature range: -5°C to +40°C. - Suited for residential/commercial use; avoid industrial-grade applications involving high harmonic frequencies or heavy-load motors exceeding spec ratings. - No auxiliary/contact signaling included—must verify direct monitoring status separately via panel systems.
