Product details

Breaking capacity and fault clearing

This breaker carries a 100 kA rated short-circuit breaking capacity across the full voltage range: 240 V, 400 V, 500 V, and 690 V AC (–).

Depth is 96 mm, height 97 mm — check the gland plate clearance if the panel is shallow. No side or backward spacing required, so you can pack modules tight.

The main circuit accepts solid conductors: 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²). Stranded: 2×(1…2.5 mm²) or 2×(2.5…6 mm²). AWG equivalent for the main contacts is 2×(14…10). The auxiliary switch is transverse design and the product extension auxiliary switch is available. Wire the load side to the motor contactor; the breaker's own auxiliary contacts can feed a PLC input for status feedback.

Substance prohibitance date of 01.05.2012 aligns with RoHS compliance — the part is free of restricted substances per EU Directive 2011/65/EU. Shock resistance rated at 25 g for 11 ms. Mounting position is any, giving flexibility in panel layout.

Frequently asked questions

What is the continuous current rating of 3RV1021-0BA15-ZX95?

The continuous rated current is 0.2 A. This is the current the breaker is set to protect at; it will trip on overload above this value per the CLASS 10 curve.

What breaking capacity does 3RV1021-0BA15-ZX95 have at 400 V?

100 kA at 400 V AC. The same 100 kA rating holds at 240 V, 500 V, and 690 V AC.

Will 3RV1021-0BA15-ZX95 drop into a panel specified for 3RV1011-0GA10?

Both are SIRIUS motor protection breakers on the same 45 mm DIN-rail footprint, so mechanical fit is the same. Verify the continuous current setting: 3RV1021-0BA15-ZX95 is 0.2 A; the 3RV1011-0GA10 may have a different range. Wire sizes and terminal types are identical screw-type terminals.

Where can I buy 3RV1021-0BA15-ZX95 and how is it quoted?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time. Submit an RFQ for volume or single-unit needs.
