It's designed as a selective (time-delayed) device to coordinate with the 5SL series of miniature circuit breakers — meaning it sits upstream and lets downstream short-circuit protection clear first before tripping on a ground fault. That selectivity is key in a distribution board where you don't want the main RCD dumping the whole panel for a fault on one branch. RoHS compliant since 30 June 2025, and REACH Article 33 duty-to-inform data is available on the current candidate list. No export restrictions (AL: N / ECCN: N). The packaging dimensions are 130 x 105 x 81 mm, shipped as a single piece.","metaTitle":"Siemens 5SM2746-8 RC Unit, 4-pole Type A, 63 A, 500 mA, 400","metaDescription":"Siemens 5SM2746-8 RC unit, 4-pole, type A, rated 63 A, 500 mA residual, Un AC 400 V, selective for 5SL.
