Duty ratings and real-world current
The 3AXD50000049066: Normal-use output current is 650 A (355 kW), heavy-duty is 477 A (250 kW), and light-overload is 634 A (355 kW). The UL listing shows 650 A normal, 477 A heavy-duty (400 Hp), and 623 A light-overload (500 Hp). These are the numbers that govern cable sizing and thermal management in the panel.
Mounts as a module — IP00 open type, so it needs a clean, dry cabinet. Ambient temperature max 40 °C, altitude 1000 m without derating. Standby loss is 423 W; sound level 72 dB(A). Operating humidity up to 95% RH. The R10 frame is a substantial piece of iron — plan the gland plate and busbar clearance accordingly.
I/O and auxiliary details
Onboard I/O: 2 analog inputs, 2 analog outputs, 6 digital inputs, 3 digital outputs. No industrial Ethernet interface (0 hardware interfaces). The control unit includes a CR2032 lithium coin cell (220 mAh, 3 V) for backup.
