Design Of The Productfor motor protection

Product details

The breaker handles 1.5 kW at 400 V AC (AC-3 duty) and delivers a 100 kA breaking capacity at 400 V AC — enough to clear a hard fault without cascading upstream.

Breaking capacity and fault handling

Breaking capacity is 100 kA at 240 V, 400 V, and 500 V AC, dropping to 6 kA at 690 V AC. No ground fault detection on this variant.

Terminal wiring and aux contacts

Main current circuit terminals are screw-type. Solid conductors: 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). The auxiliary switch is transverse design and rated: 1 A at 24 V, 0.5 A at 230 V, 0.15 A at 60 V. No auxiliary contacts are included as standard — the auxiliary switch is built into the breaker body.

Frequently asked questions

What is the continuous current rating of 3RV1021-1FA15-ZW98?

The continuous current rated value is 5 A.

What is the breaking capacity at 400 V?

100 kA at 400 V AC.
