Rated 415 V AC, 50/60 Hz, it fits into standard DIN-rail distribution boards as a 4-module-width unit (72 mm wide). Rated breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 — the higher IEC figure applies when the breaker is used in industrial panels where prospective fault current can exceed 10 kA. The 15 kA rating at 415 V AC gives selectivity headroom downstream of a larger upstream device; you can coordinate this 2 A Z-curve with a 63 A or 100 A upstream MCB without losing discrimination. Snap-on DIN-rail mount, 72 mm wide (4 MW), 76 mm deep, 90 mm tall, with 70 mm installation depth behind the panel surface. Mounting position is any — vertical, horizontal, or flat — so it fits tight enclosures without derating. IP20 with connected conductors; sealable cover option is available for tamper-proofing in public-access distribution boards. ## Environmental and compliance range Vibration rated at 50 m/s² from 25 to 150 Hz per IEC 60068-2-6, suitable for machine-mounted panels on conveyors or compressors.","metaTitle":"Siemens Betagard 5SL4402-0RC MCB, 2A 4P Z-Curve, 10kA","metaDescription":"Siemens Betagard 5SL4402-0RC miniature circuit breaker, 2A 4-pole Z characteristic, 10 kA per EN 60898 / 15 kA per IEC 60947-2.

The Z curve trips faster on low-level faults, making the 5SL4402-0RC the correct choice for semiconductor protection; the 5SL4363-7 is a general-purpose C-curve device for standard circuits.
