It carries a thermal current rating of 63 A and an operating voltage of 500 V AC, making it suitable for feeding multiple 3RV2 circuit breakers from a single power source. This busbar is specifically intended for use with circuit breakers of the 3RV2 series in frame sizes S00 and S0. It accommodates two switches, providing a clean, pre-assembled power distribution path that eliminates individual wiring between breakers.
The busbar can be installed in any orientation, and the clearance requirements are minimal: 10 mm upward, 0 mm backward, and 0 mm at the sides — meaning it can be placed flush against the backplane and adjacent components. The electrical connection is plug-in type without terminals — the busbar pins insert directly into the circuit breaker's power terminals. This saves panel wiring time and reduces the chance of loose connections at high current.
Electrical ratings and compliance
Rated operational current is 63 A, matching the thermal current (Ith). The 3-pole design covers all three phases in a single assembly. Ambient temperature range during operation is -20 to +60 °C. The product complies with RoHS substance restrictions per the 2009/10/01 date, and the SIRIUS brand carries CE, UL, and CSA certifications typical for this product family.
