160 A, 187 kA interrupting — the numbers that matter for your panel
The Siemens 3VA1116-5ED32-0AB0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current at 40 °C, across a 3-pole configuration. Its interrupting capacity hits 187 kA at 240 V and 121 kA at 415 V — figures that govern whether this breaker clears a fault without upstream damage in high-available-fault-current panels. No undervoltage release, no phase-failure detection, no communication function — this is a straight line-protection breaker, not a multifunction device.
The 160 A rating holds flat from 40 °C to 50 °C, then derates to 153.6 A at 55 °C and 144 A at 70 °C. If your panel ambient runs hot, that 144 A at 70 °C is the real limit — not the nameplate 160 A. The 187 kA at 240 V is the peak short-circuit current this breaker can safely interrupt; at 690 V it drops to 17 kA, so verify the available fault current at your service voltage.
Panel fit and auxiliary contacts
The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm tall. No voltage trigger or undervoltage release is fitted; if you need undervoltage protection, this variant won't do it without an add-on accessory.
