What this 63 A MCCB delivers in a panel
It sits in a 76.2 mm wide, 130 mm tall, 70 mm deep footprint — a standard three-module width on DIN rail, so it occupies the same slot as most 63 A frame MCCBs. The interrupting capacity is what sets this part apart: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. The 63 A rating holds flat from 40 °C through 50 °C, then derates to 60.48 A at 55 °C and 56.7 A at 70 °C; if your panel ambient pushes past 50 °C, size the load at the derated value, not the nameplate.
What the auxiliary switch complement means for integration
The breaker ships with 2 auxiliary switches configured as HQ (high-quantity) contacts — these are built-in, not field-added. The TM240 release is fixed thermal and magnetic — no adjustable trip curve, no electronic trip unit. That makes it a straightforward fit for standard motor branch circuits or feeder protection where you don't need coordination tweaking.
