What this MCCB brings to a panel
Rated 32 A continuous at 40 °C, it holds that rating all the way up to 50 °C before it starts to taper (31 A at 55 °C, 30 A at 70 °C), so in a warm enclosure you lose very little headroom.
Interrupting ratings across voltages
This MCCB's interrupting capacity is voltage-sensitive, as you'd expect. At 415 V it's rated 75.6 kA, at 440 V it drops to 52.5 kA, and at 500 V and 690 V it holds at 11.9 kA. If your distribution runs at 400 V class (common for industrial panels outside North America), that 75.6 kA at 415 V gives you a comfortable margin over most 400 V fault currents.
Dimensions are 130 mm tall, 76.2 mm wide, 70 mm deep — a standard SENTRON 3VA frame size for a 32 A 3-pole. It snaps onto DIN rail (the 3VA series uses the same mounting footprint as earlier 3VL breakers in many cases), so swapping into an existing panel that was laid out for a 3VA or 3VL of similar rating should work without drilling new holes. The undervoltage release is factory-integrated, not a field-addon kit, so you don't lose the side space for auxiliary contacts — worth noting if the panel is tight.
What the TM240 overcurrent release means
The overcurrent release is a TM240 — thermal-magnetic, fixed thermal rating at 32 A (the TM240 designation means the thermal element is set for a 32 A frame), with a magnetic trip that's adjustable. Thermal-magnetic means it handles overloads (slow, heat-based) and short circuits (fast, magnetic) in one package. No electronic trip unit here, so no adjustable long-time or short-time pickup curves — it's simpler and more rugged, which suits line protection where you want a fixed thermal characteristic and a magnetic trip that clears faults fast.
