That's a standard feature on SIRIUS 3RV1 breakers, not an add-on accessory. IP20 on the front — finger-safe for the panel face, but not washdown-rated; keep it inside a cabinet. Terminals accept solid and stranded copper: 2x (1 … 2.5 mm²) and 2x (2.5 … 6 mm²) per clamp, with AWG equivalents 2x (14 … 10) for the main contacts. Finely stranded with ferrule is also supported. That covers most motor feeder cables up to 6 mm². Shock-rated at 25g / 11 ms — tough enough for machine-mounted panels on presses or conveyors. Above that, you'd need to account for reduced air density on the arc extinction and thermal dissipation. That's warm but manageable in a ventilated enclosure; factor it into the panel thermal budget if you're packing several in a row.","metaTitle":"Siemens 3RV1021-1JA10-0FJ0-ZX95 SIRIUS Motor Protection CB,","metaDescription":"Siemens SIRIUS 3RV1021-1JA10-0FJ0-ZX95 motor protection circuit breaker, 10 A continuous, Class 10 trip, 100 kA SCCR at 400 V, phase failure detection.

The 3RV1021-1JA10-0FJ0-ZX95 has screw terminals for the main current circuit, so a swap to the 3RV6 variant may require a terminal adapter or re-termination in the panel."},{"question":"What is the depth of 3RV1021-1JA10-0FJ0-ZX95?","answer":"The depth is 96 mm, measured from the DIN rail mounting surface to the front of the device."},{"question":"What wire sizes does the 3RV1021-1JA10-0FJ0-ZX95 accept?","answer":"Solid and stranded conductors: 2x (1 … 2.5 mm²) and 2x (2.5 … 6 mm²) per terminal.
