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.
