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. The TM210 thermal-magnetic release handles overload and short-circuit protection in one package, with a fixed time delay tr of 1 second at the rated current. No undervoltage release, no phase-failure detection, no communication function — this is a straight line-protection breaker, not a multifunction device.
What the ratings mean for fit
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. The 800 V rated insulation voltage (Ui) sets the maximum system voltage the breaker can live with, not what it switches — it's a coordination number for the designer.
Panel fit and auxiliary contacts
The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm tall. It ships with 2 auxiliary switches (HP type) for status feedback to a PLC or indicator light — wired separately, not integrated into the trip unit. The front face carries IP40 protection, so it's fine for a dry indoor panel but not for washdown areas. No voltage trigger or undervoltage release is fitted; if you need undervoltage protection, this variant won't do it without an add-on accessory.
