What the 25 A TM-D and 70 kA breaking capacity mean for your panel
It carries a 25 A thermal-magnetic TM-D trip unit that provides L (overload) and I (short-circuit) protection per IEC 60947-2. The key specification for fit is the breaking capacity: 70 kA Icu at 380/415 V AC, 50/60 Hz.
Breaking capacity across common voltages
This 4P breaker delivers 100 kA Icu at 240 V AC, 70 kA at 415 V, 65 kA at 440 V, 50 kA at 500 V, 35 kA at 525 V, and 10 kA at 690 V AC. For UL 60947-4-1 applications it's rated 85 kA at 240 V AC, 65 kA at 480 V, and 10 kA at 600 V. The H breaking capacity code means it's sized for high-fault panels, not the economy F or J tiers.
Mounting and enclosure integration
The 4P breaker occupies 140 mm width on a 35 mm connection pitch, with a depth of 86 mm and height of 161 mm. IP40 enclosure protection and IK07 impact resistance suit it for standard panel environments, not washdown zones.
