Product identity and core ratings
The CLASS 10 trip characteristic ensures it clears overcurrents fast enough to protect motor and transformer windings during locked-rotor events.
Dimensions are 45 mm wide, 97 mm deep, and 97 mm high — that 45 mm width is a standard 2.5-module footprint, so it fits a typical panel's gland-plate layout without surprises. Minimum clearance to adjacent components: 50 mm upwards and downwards, 30 mm at the side, 0 mm forwards and backwards.
Protection features and environment
Includes phase failure detection, so it will trip if one phase drops out — useful for transformer primary protection where single-phasing can cause overheating. Ground fault detection is not built in. Rated operating voltage spans 20 to 690 V.
Short-circuit coordination with fuses
Short-circuit ratings depend on upstream fuse type: at 400 V, the breaker is rated for gL/gG 63 A fuses; at 500 V and 690 V, it requires gL/gG 50 A.
