The 5SL4363-7: Siemens SENTRON MCB, 3-pole, 63A, C-curve, 400V AC, 10 kA breaking capacity.
Width 54 mm (3 modular units), depth 76 mm, height 90 mm, installation depth 70 mm. Any mounting position, sealable, IP20.
Rated 400 V AC, 440 V max multi-phase, 50/60 Hz. Tripping characteristic C. Breaking capacity 10 kA. Power loss 5 W per pole.
Yes. Width is 54 mm (3 modular units), depth 76 mm, installation depth 70 mm. The any-position mounting and 70 mm installation depth are compatible with common 18-module enclosures that accept 3-pole MCBs of standard profile.
Yes. The product is explicitly halogen-free and silicon-free. Those are listed as construction materials attributes, compliant with RoHS directives. For OSHA exposure limits, the silicone-free aspect reduces contamination risk in controlled environments.
IP20 with conductors connected means the breaker is touch-safe (finger protection) but not dust-tight or moisture-resistant. The sealable design helps if the enclosure has gasketed doors, but for resale in humid or dusty conditions, the overall enclosure IP rating must be higher. This MCB alone is not rated for ingress of dust or water.
Yes. Overvoltage category III is typical for fixed installations downstream of the main distribution board — it handles impulse voltages up to 4 kV at 400 V. Pollution degree 2 assumes non-conductive pollution with temporary condensation. Together they cover the transient environment of most industrial control cabinets.
