Transformer-protection circuit breaker, 6.3 A, Class 10
Finger-safe touch protection (IP20 on the front) meets panel safety requirements.
The 6.3 A continuous rating sets the maximum steady load the breaker carries without tripping. Power dissipation is 7.25 W total in hot operating state (2.4 W per pole). That heat must be considered in enclosure sizing, especially when multiple breakers are ganged in a small panel. Maximum operating frequency is 15 cycles per hour in AC-3 duty — not a high-cycling device; it is sized for occasional switching, not repetitive motor starting.
Panel integration
The 45 mm width occupies one standard module slot. Screw terminals accept 2x (1...2.5 mm²) or 2x (2.5...6 mm²) solid or stranded — strip length and ferrule size per the terminal spec. Auxiliary switch option (product extension available) fits the same footprint. Shock rated at 25g for 11 ms; vibration resistance not listed but the DIN-rail clip holds under typical industrial panel conditions. Backwards and side clearances are 0 mm — can be mounted flush against adjacent devices.
