Techna’s Rtec489 10kA Residual Current Circuit Breakers with Overcurrent Protection (RCBOs) are UL Listed as Circuit Breakers with Equipment Ground Fault Protection to Standard 489, File E475400. Our Rtec489 are combined Branch Circuit Breakers and Ground Fault Protectors, featuring dual pole switching (live and neutral disconnect) and designed to provide protection against short circuits, overloads, AC ground faults (residual current faults) as well as pulsating DC ground faults.
Our range of Rtec489 10kA Branch Circuit Breakers with Equipment Ground Fault Protection (RCBOs) are available in 2 pole, in current ratings from 5A to 40A, with residual current sensitivity from 10mA to 300mA, in trip curves B, C and D and are suitable for mounting on DIN-Rail.
We offer three different 2 pole versions, the LN (1P+N) is a 120V or 240V single phase system with neutral connection, the LL (2P) is a 120/240V split phase system with no neutral connection and the LLN (2P+N) is a 120/240V split phase system with neutral connection.
