The 5SJ4303-7HG41: Rated from -40 °C to 75 °C with IP20 protection (IP40 around the handle) and vibration resistance up to 50 m/s², this MCB will survive the route — hot pump houses, cold storage, or a conveyor line with constant rattling. It's also halogen- and silicon-free, so it won't outgas in clean-ish industrial zones. At 54 mm wide (3 modular units), it fits a standard slot.
