Design Of The ProductFor motor protection

Product details

The 45 mm width and 75 mm depth leave room for adjacent contactors or overload relays on the same rail — a common layout in motor starter combos.

Trip class and switching duty

Maximum switching rate is 15 operations per hour under AC-3 duty, which covers the typical starting cycle of a motor starter.

Fuse backup coordination

For installations where the prospective fault current exceeds the breaker's rated breaking capacity, the evidence lists required upstream fuse sizes: gL/gG 20 A at 400 V, 16 A at 500 V, and 16 A at 690 V. This lets the panel designer coordinate the breaker with a smaller upstream fuse rather than oversizing the entire branch.

Frequently asked questions

What is the breaking capacity of 3RV1011-0KA15?

The breaking capacity is 100 kA at 400 V, 100 kA at 500 V, and 2 kA at 690 V.

Where can I buy 3RV1011-0KA15?

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

Will 3RV1011-0KA15 drop into a panel specified around 3RV1011-0GA10?

Both mount on 35 mm DIN rail per DIN EN 60715, so the mechanical fit is the same. Verify the thermal setting range and auxiliary contact configuration against your BOM — the 0KA15 carries a Class 10 trip, which may differ from the 0GA10's characteristic.
