The 3VA1163-5EE32-0JH0: The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That 187 kA figure at 240 V means this breaker can safely clear a fault on a high-capacity transformer secondary without upstream fuses needing to coordinate — it's sized for high-fault panels, not just branch protection. The overcurrent release is a TM220 thermal-magnetic type — fixed thermal and magnetic settings, no electronic adjustment. For a panel builder, that means no programming step during commissioning; the trip curve is determined by the breaker hardware. A shunt trip (STL) release is built in, and the auxiliary contact block carries 2 auxiliary switches plus 1 trip alarm switch (HQ configuration).
Sizing and derating for panel fit
Footprint is 76.2 mm wide × 130 mm high × 70 mm deep. The width is a standard 3-pole MCCB pitch — fits a 76.2 mm (3-inch) DIN-rail or panel-mount cutout without adapters. Depth of 70 mm clears most 200 mm deep enclosures with room for wiring gutters. Current derating is specified per ambient: holds 63 A up to 50 °C, then drops to 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. If the panel ambient hits 55 °C, the breaker still carries 60 A — no need to oversize for a warm enclosure. IP40 on the front face means it's protected against tools and wires >1 mm, but the enclosure itself must keep out moisture. Rated insulation voltage Ui is 800 V, so the breaker is rated for 690 V systems (line-to-line) with margin. The 690 V interrupting rating of 17 kA is the limiting case for high-voltage industrial networks.
Lifecycle and sourcing reality
The auxiliary trip release order code is 3VA9688-0BL32 (the shunt trip module). If the panel already has that module, verify compatibility — the breaker ships without the shunt trip pre-installed; it's a separate line item.
