Product description
The thermal overload release of the Siemens 3RV1021-0HA15 can be adjusted between 0.55 and 0.80 A. This three-pole SIRIUS power circuit breaker provides motor protection and belongs to frame size S0. Its tripping characteristic corresponds to CLASS 10; additionally, a magnetic short-circuit release with a pickup value of 10 A operates. Thus, this exact variant combines overload and short-circuit tripping in one compact switching device. The main circuit operates with AC voltage and is conducted via three poles. The rated operating voltage ranges up to 690 V. The operating frequency of the main circuit is 50 to 60 Hz. The standard switching capacity distinguishes this model from variants with increased switching performance. Main conductors are connected via screw terminals, and operation is performed via a front-mounted rotary switch. The adjustment scale allows assignment of the thermal release to the intended motor current. A lateral auxiliary switch is already mounted. It provides one normally open (NO) contact and one normally closed (NC) contact, supplementing the main circuit with two separate signal outputs. Installation is on a 35-mm DIN rail; for wiring, a Pozidriv screwdriver size 2 is required. The device width is approximately 46 mm. The overall dimensions are approximately 46 × 97 × 99 mm. The net weight is 0.301 kg. Therefore, the technical selection depends not only on the current range but also on frame size, tripping class, short-circuit pickup value, connection type, and auxiliary contact configuration. Within the 3RV1021 series, the suffix 0HA15 specifically identifies the combination of a 0.55-to-0.80-A adjustment range, standard switching capacity, and pre-mounted contact pair 1 NO + 1 NC. Adjacent current ranges have different order numbers.

What motor current range does the Siemens 3RV1021-0HA15 cover?
The thermal overload release can be adjusted from 0.55 to 0.80 A; the tripping characteristic corresponds to CLASS 10.
Which auxiliary contacts are available on this variant?
The lateral auxiliary switch provides one normally open (NO) contact and one normally closed (NC) contact; the short-circuit release is specified at 10 A.
What applies if an item develops a defect within 14 days?
For the condition categories “Used, removed from an installation” and “New, old stock”, the contractual 14-day right of return in the event of a defect applies. The defect must occur within 14 calendar days after delivery and be reported in text form within the same period.
In particular, the REHA tamper-evident seal must remain fully intact and our RMA approval is required before return. In an accepted case, we decide between replacement and refund. Details in Section 11 of the Terms.
Which shipping methods and delivery times are available?
The shipping method, shipping cost and estimated delivery time are confirmed for the specific order. Depending on the item, destination and urgency, we can check parcel, express or freight shipping as well as collection.

No. There is no general B2B right of return, exchange, cancellation or withdrawal. Incorrect or duplicate orders and a lack of suitability or compatibility with the customer’s installation are not covered by the contractual 14-day right of return in the event of a defect. Details in Section 12 of the Terms.
Can I request individual pricing for several items?
You may request an individual quotation for several items or larger quantities. We then check availability and pricing for the specific requirement; there is no entitlement to a quantity discount. Open the quick enquiry.
Do you also purchase industrial spare parts?
Yes. You can offer us automation and drive components for purchase. Please provide complete type numbers, quantities, condition details and photographs where possible.
After review, we will tell you whether a purchase is possible and on which terms. Learn more about selling industrial stock.
