ALBO Residual Current Operated Circuit Breaker(RCBO)
Product Details
Product Descriprion
The ALBO RCBOs provide integrated protection against earth leakage, overload, and short circuits in both 1P+N and 3P+N configurations, meeting the requirements of diverse applications from home use to large-scale engineering and wholesale distribution. Compliant with EN IEC 61009-1, they offer a breaking capacity of 6kA and support both B and C tripping characteristics for different inrush conditions. With adjustable sensitivity from 10mA to 300mA and rated currents from 3A to 40A, these devices enable tailored safety solutions for both shock and fire prevention in any installation.
Designed for 35mm DIN rails with a compact two-module width, the RCBOs feature lug or pin terminals and include clear specifications for conductor cross-sections and tightening torque, supporting consistent assembly in mass-produced distribution panels. They trip within 0.04 seconds at 30mA leakage, ensuring rapid response even in high-demand commercial circuits. With an IP20 rating and slim profile, they are ideal for use in residential and commercial distribution boards to protect sockets, lighting, HVAC, and sensitive equipment in both small-scale and large-scale projects.
