Mount in any position. Temperature derating is published: 63 A at 30 °C, 59.85 A at 40 °C, 56.7 A at 50 °C, 54.18 A at 60 °C. If your panel ambient runs 50 °C, you're looking at 56.7 A continuous — plan your load accordingly. Three poles = 16.5 W total heat to shed inside the enclosure.
Halogen-free and silicon-free construction. Sealable — useful if your site requires lockout-tagout on the breaker handle.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time — send the order code and quantity.
Depth is 76 mm, width 18 mm (one modular unit), height 90 mm. Installation depth is 70 mm.
Both are 3-pole C-curve MCBs in the same Betagard family with identical 18 mm per-pole width and DIN-rail clip. The 5SL4363-7 is a 63 A variant — same footprint, same mounting, same terminal layout. Panel wiring transfers directly.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
