It accepts solid conductors up to 2x 10 mm² and stranded up to 2x 16 mm² (or 1x 25 mm²), with a maximum ampacity of 40 A. The insulation voltage is rated 690 V AC at pollution degree 3. Designed for Size S0 circuit breakers, the 3RV1928-1H mounts directly on the breaker's line or load side. Dimensions are 44.8 mm wide, 38.9 mm high, and 73.6 mm deep. Screw-type terminals accept a wide range of conductor sizes: solid 2x (1–10 mm²), stranded 2x (2.5–16 mm²) plus 1x (1.5–25 mm²), and with core-end processing 1x (1–16 mm²) or 2x (1–10 mm²).","metaTitle":"Siemens 3RV1928-1H SIRIUS Terminal Block, Type E, 40A, S0","metaDescription":"Siemens 3RV1928-1H SIRIUS terminal block, Type E per UL 508, 40A, for Size S0 breakers.
