It carries a 20 A continuous rating across ambient temperatures from 40 °C to 55 °C, derating to 19 A at 60 °C and 65 °C, and 19 A at 70 °C — so the full 20 A holds through typical panel ambient conditions, with a small derate only above 55 °C.
Rated breaking capacity reaches 121 kA at 240 V AC, dropping to 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. At 415 V the 75.6 kA still covers most industrial panelboards.

The 4-pole configuration suits three-phase plus neutral or three-phase with switched neutral applications. Maximum power loss is 12 W, a figure to consider for thermal dissipation in a sealed enclosure.
Dimensions are 70 mm depth, 101.6 mm width, 130 mm height. Front protection is IP40.
