The 45 A rated current (Ithmax 1) is the thermal continuous rating at 40 °C ambient, thermal class B per IEC 60085 — meaning the winding insulation is rated for 130 °C hot-spot, which governs the derating curve if your cabinet ambient runs higher. The 63 A peak current handles inrush and transient overloads typical of converter charging circuits. Total coil power loss is 55 W (plus 14.5 W iron-core loss), so the choke dissipates roughly 70 W at full load — factor that into your panel thermal budget. The 0.45 mH inductance with 4 % voltage drop is sized for a specific converter DC-link ripple and fault-current limiting; substituting a choke with different %Z changes the commutation behaviour and may require re-coordination of the upstream fuse or breaker. No official successor order code has been assigned, so this remains the direct drop-in for any BOM line specifying the 4EP3800-3DS00.","metaTitle":"Siemens 4EP3800-3DS00 Commutating Choke, 45A 400V 50Hz","metaDescription":"Siemens 4EP3800-3DS00 commutating choke for converter, 3-phase, 45A rated, 400V AC, 50Hz, 0.45mH, IP00, screw terminals.
