Product details

Zero clearance required at the sides and rear, so it packs tight on a DIN rail without forced air gaps. Any mounting position allowed, which simplifies layout in crowded enclosures.

Termination and wiring

Solid wire range: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²); stranded: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²). AWG equivalent for main contacts is 2x (14 to 10). The dual-wire capacity per clamp is useful when looping through to a downstream contactor or control relay — no separate terminal block needed for the pass-through.

Frequently asked questions

How do I get current pricing and availability for 3RV1021-1JA15-ZX95?

Submit an RFQ against this order code; the part is sourced through independent distribution and availability with current pricing is confirmed at quote time.

What is 3RV1021-1JA15-ZX95's listed depth?

Depth is 96 mm, width 45 mm, height 97 mm.

What solid wire sizes does 3RV1021-1JA15-ZX95 accept?

Solid wire: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²). Stranded: 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²).

Will 3RV1021-1JA15-ZX95 drop into a panel specified around 3RV2021-1FA15 without rewiring?

Both are SIRIUS motor protection breakers with the same 45 mm width and snap-on DIN rail mounting, but the 3RV2021-1FA15 is a higher-current variant (typically 22 A continuous). The 3RV1021-1JA15-ZX95 is rated 10 A continuous, so it fits the same footprint but only if the motor FLA is within its range. Terminal wire ranges are similar; no rewiring of the DIN rail or enclosure cutout is needed.

What compliance documentation does Siemens provide for 3RV1021-1JA15-ZX95?

The part carries a substance prohibition date of 01.05.2012, indicating RoHS compliance per EU Directive 2011/65/EU. Full documentation (UL, CSA, CE, IEC) is available from Siemens via the product datasheet and certificate portal.
