Product details

The 97 mm cube footprint and 45 mm width fit standard 45 mm module spacing on 35 mm DIN rail. Screw terminals for the main circuit accept 2x (0.75–2.5 mm²) solid or stranded, or 2x 4 mm² — sized for motor branch circuit conductors. The gL/gG fuse backup values at 400 V (63 A,), 500 V (50 A,), and 690 V (40 A,) define the upstream fuse limits for selective coordination.

Mounting position is any, with clearance requirements: 50 mm upward and downward, 30 mm at the side, zero forward and backward. The M3 main contact screws are standard for panel wiring.

Frequently asked questions

What is the short-circuit breaking capacity of this breaker?

100 kA at both 240 V and 400 V. At 500 V it is rated 42 kA, and at 690 V it is 4 kA.

Does the 3RV2011-1KA10 include phase failure detection?

Yes, phase failure detection is built into this device. Ground fault detection is not included.

What trip class is this circuit breaker?

Class 10, which means it will trip within 10 seconds at 7.2× the thermal current setting — standard for general-purpose motor protection.
