That 10 kA interrupting rating means it can clear a fault current up to 10,000 amps without welding its contacts or rupturing the enclosure — a standard requirement for residential and light-commercial panelboards where the prospective short-circuit current stays under that threshold. Occupies 3 modular width units — 54 mm wide — and requires 70 mm of clear installation depth behind the panel surface. The 76 mm overall depth includes the housing and terminals; plan for front-access wiring clearance. Rated for ambient temperatures from -40 °C to +75 °C, with a 95% humidity limit at +55 °C. Vibration resistance tested to 50 m/s² at 25–150 Hz per IEC 60068-2-6. Sealable — the toggle can be locked or sealed in the OFF position for lockout/tagout compliance.","metaTitle":"Siemens 5SL4302-7CC SENTRON MCB, 3P C 2A 10kA 400V","metaDescription":"Siemens 5SL4302-7CC SENTRON miniature circuit breaker, 3-pole, C-curve, 2 A, 10 kA at 400 V AC.

The difference is the current rating and curve; 5SL4363-7 is a 63 A C-curve, while this is 2 A C-curve. If the panel busbar and wiring are sized for 63 A, dropping in a 2 A breaker is electrically safe but will trip on the existing load.
