Product details

Zero clearance needed at the sides or rear — the 70 mm width and 165 mm height fit tight sub-panels; the 174 mm depth leaves room for gland plates. Screw-type box terminals on the main circuit accept 2x solid (2.5 to 16 mm²) or 2x stranded (10 to 50 mm²) with a single 70 mm² option. AWG 10 to 1/0 on the mains. Wire up without derating for side-by-side packing.

Protection and ratings

Phase-failure detection is built in; ground-fault detection is not. The 690 V rated insulation voltage and 6 kV surge withstand suit it for 480/277 V and 600 V nominal systems.

Frequently asked questions

Where can I buy the 3RV1041-4HA10-ZX95?

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

What is the breaking capacity of this breaker at 400 V?

50 kA at 400 V AC. Also rated 100 kA at 240 V, 12 kA at 500 V, and 6 kA at 690 V.

Does the 3RV1041-4HA10-ZX95 fit on a standard DIN rail?

Yes, it snaps onto 35 mm mounting rail per DIN EN 50022. Requires zero clearance at the sides or rear for mounting.

What wire sizes does the main circuit accept?

Solid: 2x (2.5 to 16 mm²). Stranded: 2x (10 to 50 mm²) or 1x (10 to 70 mm²). AWG equivalents 10 to 1/0.
