Product details

Motor protection circuit breaker for the 0.4 A line

Its 0.4 A continuous rated current covers small motor loads — the 0.09 kW rating at 400 V puts it on fractional-horsepower pumps, fans, and conveyor drives. The CLASS 10 trip characteristic matches standard motor start profiles, allowing the breaker to ride through the inrush without nuisance tripping.

Breaking capacity and fault clearance

Short-circuit breaking capacity is a flat 100 kA across the AC voltage range from 240 V to 690 V (–). The 100 kA rating is the same at 400 V and 690 V, so it holds up even on 690 V industrial grids.

Main circuit terminals accept solid conductors from 2x (0.5... 1.5 mm²) to 2x (0.75... 2.5 mm²) and stranded from 2x (1... 2.5 mm²) to 2x (2.5... 6 mm²). Auxiliary and control circuit terminals are also screw-type, so the whole unit is wired with one screwdriver. IP20 front protection is standard for enclosed panels.

Auxiliary switch and control signals

The breaker accepts a transverse auxiliary switch — the product extension is available, meaning you can add a signal contact for remote fault indication or PLC input. The auxiliary contacts are rated 1 A at 24 V, 0.5 A at 230 V, and 0.15 A at 60 V. These ratings are for the control circuit; the main power path handles the motor current.

Frequently asked questions

What is the breaking capacity of 3RV1021-0EA15-ZW98?

The short-circuit breaking capacity is 100 kA at 240 V, 400 V, 500 V, and 690 V AC (–), making it suitable for high-fault-current industrial panels.

Does 3RV1021-0EA15-ZW98 detect phase failure?

Yes, phase failure detection is built in, so the breaker will trip if one phase is lost — protecting the motor from single-phasing.

What wire sizes does the 3RV1021-0EA15-ZW98 accept?

Solid conductors: 2x (0.5... 1.5 mm²) and 2x (0.75... 2.5 mm²). Stranded: 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²). AWG equivalents for main contacts: 2x (14... 10).

Where can I buy 3RV1021-0EA15-ZW98 and get current pricing?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm quote.

What compliance documentation does Siemens provide for 3RV1021-0EA15-ZW98?

The substance prohibition date of 01.05.2012 indicates RoHS compliance. Standard Siemens documentation includes the datasheet, CE declaration, and UL/CSA file information available on request.
