The 3-pole design with toggle control and front-front connections suits panel layouts where top and bottom cable access is needed.
The F breaking capacity code delivers 85 kA Icu at 220/240 V AC and 36 kA at 380/415 V AC, dropping to 22 kA at 525 V and 8 kA at 660/690 V. At 415 V, the 36 kA rating gives solid fault-clearing headroom for most industrial distribution boards; the 200 A TM-D trip provides L (thermal overload) and I (magnetic short-circuit) protection in one unit, with no earth-leakage module onboard.
The 105 mm width, 161 mm height, and 86 mm depth fit standard panel cutouts for the NSX250 frame.
Electrical durability and thermal budget
Rated for 20,000 mechanical cycles and 10,000 electrical cycles at 440 V In. Power dissipation is 15.4 W per pole, totaling about 46 W for the 3-pole unit at rated load — factor this into enclosure ventilation.
