Product details

DIN rail fit and wiring

The 45 mm wide body accepts solid or stranded conductors: 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²) per terminal. Depth is 96 mm, height 97 mm — fits standard distribution boards without crowding the gland plate.

Breaking capacity and duty cycle

Rated short-circuit breaking capacity holds at 100 kA across the voltage range: 240 V, 400 V, 500 V, and 690 V AC. That's consistent fault clearance regardless of supply voltage within the rated range. Maximum operating frequency is 15 operations per hour at AC-3 duty — fine for motor starting, not for rapid cycling. Power dissipation is 5.5 W hot, 1.8 W per pole, so derating in a sealed enclosure is worth checking if you're packing multiple units.

Frequently asked questions

Where can I buy 3RV1021-0EA10-ZW96 and get a price?

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 price and lead time.

What's the closest functional second-source to 3RV1021-0EA10-ZW96?

The 3RV1011-0GA10 is a similar SIRIUS motor protection breaker but with different trip characteristics and terminal layout. It will not drop into a panel wired for the 3RV1021 without checking the mounting footprint and conductor sizing — the 3RV1021 uses screw terminals while the 3RV1011 series may differ in terminal type and wire range.

What is the depth of 3RV1021-0EA10-ZW96?

The depth is 96 mm, with a width of 45 mm and height of 97 mm. It mounts on 35 mm DIN rail with zero clearance needed at the sides or rear.
