The 72 mm width (4 modular units) and 76 mm depth fit standard 36 mm-wide module spacing — plan for a 4-pole slot in the distribution board. IP20 rating applies with connected conductors; the touch-protection feature means finger-safe terminals when wired.
At DC (per IEC 60947-2) it is rated 15 kA; under UL 1077 / CSA C22.2 No. 235 it is 5 kA. The 70 kA figure means it can be installed at the service entrance or on a high-fault bus without requiring a current-limiting upstream fuse.
Temperature derating is published: at 45 °C the rating holds at 0.5 A; at 50 °C it drops to 0.49 A; at 55 °C to 0.47 A. Ambient humidity limits are specified per the surrounding-temperature influence table. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. These matter for installation on a machine frame or near rotating equipment.
