The Siemens SENTRON 3VA2163-5HL36-0JH0 is a 3-pole molded case circuit breaker rated for 63 A continuous current at 40 °C, with no derating needed all the way up to 70 °C — every temperature point in the evidence shows 63 A solid. That means it holds its full rating in a hot panel, which matters when you're packing breakers tight on a DIN rail or inside a sealed enclosure. Interrupting capacity hits 187 kA at 240 V, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V.
Built for line protection with shunt trip and auxiliary switching
This MCCB is designed as line protection — it protects the feeder, not a specific load. That's enough aux contacts to signal a PLC that the breaker has tripped, or to interlock with another device. The 86 mm depth, 105 mm width, and 181 mm height fit a standard MCCB footprint — it'll drop into a SENTRON panel or any distribution board with the right busbar spacing.
