| Design Of The Product | For motor protection |
The 3RV2011-1KA25: Rated at 12.5 A at both 480 V and 600 V, this breaker is sized for a 2 hp motor at 230 V — that's a common frame size for pumps, fans, or small conveyors. CLASS 10 trip curve clears locked-rotor conditions in under 10 seconds.
The spring-loaded terminals accept 2x (0.5 to 2.5 mm²) solid or stranded, so you can land two conductors per side without ferrules. Depth is 97 mm, width 45 mm, height 106 mm.
Yes, the mounting position is any. It fastens via screw or snap-on onto 35 mm DIN rail per DIN EN 60715.
Spring-loaded terminals that accept 2x (0.5 to 2.5 mm²) solid or stranded conductors.
-20 to +60 °C during operation, -50 to +80 °C during storage and transport.
