Product Overview
SGB5L-40 series 1P+N miniature residual current circuit breaker (RCBO) is designed for 50/60Hz single-phase circuits with a rated voltage of 230/240V AC. It integrates residual current leakage protection, overload protection and short-circuit protection in one compact unit, delivering all-round safety for civil and commercial electrical systems.
This RCBO disconnects both the phase line and neutral line simultaneously, and maintains reliable leakage protection even with reverse wiring. Featuring a compact structure and high breaking capacity, it complies with EN61009-1, AS/NZS IEC 61009-1 and GB/T16917.1 standards, and is an ideal safety component for terminal power distribution.
Triple integrated protection: residual current leakage protection, overload protection and short-circuit protection
Flexible configuration: residual operating current optional in 10mA / 30mA / 50mA / 100mA; Type A and Type AC residual current protection available
1P+N structure: cuts off phase and neutral poles at the same time; leakage protection remains fully functional even under reverse wiring
Thermomagnetic tripping mechanism, with B / C instant release curves to match lighting and motor-type loads
High breaking reliability: both ultimate breaking capacity (Icu) and operational breaking capacity (Ics) reach 6kA
Standard 35mm DIN-rail mounting, compact footprint and IP20 protection, compatible with mainstream distribution enclosures
Stable performance in temperatures from -25℃ to +70℃, suitable for various indoor installation scenarios
