MCCB for line protection — 63 A, 187 kA interrupting capacity
The Siemens SENTRON 3VA1163-5ED32-0BH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 63 A at 40 °C through 50 °C, derating to 58 A at 70 °C. Its interrupting capacity hits 187 kA at 240 V AC and 121 kA at 415 V AC — numbers that put it in the high-fault-current class for industrial distribution panels where upstream transformer capacity is substantial. Rated insulation voltage is 800 V, and the unit includes an undervoltage release (UVR) as standard — a common requirement for safety disconnects on conveyor or pump circuits where loss of control power must trip the breaker. The auxiliary switch configuration carries 2 auxiliary switches plus 1 trip alarm switch (HQ type), giving the PLC or SCADA a clean status signal without external relays.
