Product details

Motor protection circuit breaker for the line

The Class 10 trip curve matches standard motor start profiles; it holds through the inrush and still clears a locked-rotor fast enough to keep the winding from cooking.

Rated continuous current is 1.6 A — that's the full-load current it's sized for. The 0.55 kW rating at 400 V tells you the motor it protects. This one doesn't, so it's a good fit for panels with high available fault current.

Depth is 96 mm, so it clears most shallow enclosures. Screw terminals accept 2x (1... 2.5 mm²) solid or stranded, or 2x (2.5... 6 mm²) — that is the range for the main circuit wiring. IP20 on the front; no washdown rating, so keep it inside the panel.

No EOL notice or successor has been issued.

Frequently asked questions

What is the breaking capacity of 3RV1021-1AA10-ZW97?

It is rated 100 kA at 240 V, 400 V, 500 V, and 690 V AC — the same high interrupting rating across the voltage range.

Where can I buy 3RV1021-1AA10-ZW97?

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

What is the trip class of 3RV1021-1AA10-ZW97?

It is Class 10, which means it trips within 10 seconds at a locked-rotor condition — standard for general-purpose motor starting.

Does 3RV1021-1AA10-ZW97 fit on a DIN rail?

Yes, it mounts on a 35 mm DIN rail per EN 50022, with screw and snap-on mounting. The 45 mm width fits standard modular panels.
