Product details

Breaking capacity and fault clearing

Rated breaking capacity hits 100 kA across the full AC range from 240 V to 690 V.

Any mounting position is allowed, and zero clearance is required at the sides or rear — you can pack these tight in a panel without derating for airflow.

Auxiliary contacts and control signals

The auxiliary switch is a transverse design, rated 1 A at 24 V, 0.5 A at 230 V, and 0.15 A at 60 V. These are the contact ratings for the signal side — feeding a PLC input or a contactor coil. The main circuit terminals accept solid conductors from 0.5 to 2.5 mm² and stranded from 1 to 6 mm², using screw-type terminals on both main and auxiliary circuits.

Sourcing note

This is a current-production Siemens SIRIUS part, sourced through independent distribution channels.

Frequently asked questions

Where can I buy 3RV1021-0DA15 and get current pricing?

The 3RV1021-0DA15 is sourced to order through independent distribution. Submit an RFQ for current pricing and availability confirmation at quote time.

What is the breaking capacity of 3RV1021-0DA15 at 400 V?

The breaking capacity is 100 kA at 400 V AC, and the same 100 kA rating holds across 240 V, 500 V, and 690 V AC.

Does 3RV1021-0DA15 detect phase failure?

Yes, phase failure detection is included. Ground fault detection is not provided.

What wire sizes fit the terminals on 3RV1021-0DA15?

Main circuit screw terminals accept solid conductors 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²), and stranded conductors 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²).
