Product details

Breaking capacity is 10 kA per EN 60898, with a secondary 5 kA rating per UL 1077 and CSA C22.2 No. 235 for North American acceptance.

Thermal derating and ambient limits

The 0.5 A rating holds at 35 °C ambient. At 40 °C it derates to 0.46 A, at 45 °C to 0.44 A, at 50 °C to 0.41 A, and at 55 °C to 0.39 A. The maximum ambient for operation is 75 °C, with a minimum of -40 °C. Humidity limits are 95% RH up to 55 °C, tapering to 35% RH at 75 °C.

Dimensions: 36 mm wide (2 MW), 90 mm high, 76 mm deep, with an installation depth of 70 mm behind the panel face. Mounting position is any orientation. The quick assembly system snaps onto standard DIN rail. Both top and bottom terminals are combined (line and load can land on either side). Touch protection is built in. The breaker is sealable, halogen-free, and silicon-free — relevant for clean-room or food-bev panel specs where outgassing matters. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz.
