What this MCB brings to your panel
The 5SY4204-8: For DC circuits, it's rated 15 kA at 60 V (up to 72 V maximum). That makes it suitable for control circuits or battery-backed loads where a standard AC-only breaker would struggle. The body is 36 mm wide (2 modular units), 76 mm deep, and 90 mm tall — a standard footprint that drops into any SENTRON distribution board or industrial enclosure with quick assembly system mounting.
Sealable cover is an option if you need to lock out setting changes after commissioning. No neutral switching, so it's a straight two-pole line breaker. Vibration-resistant per IEC 60068-2-6: ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, so it holds steady in machinery panels and conveyor control boxes.
