Rated for 440 V AC maximum operating voltage, this 1-pole unit occupies a single 18 mm modular width on the DIN rail, with a depth of 76 mm and height of 90 mm. The quick assembly system and any mounting position simplify panel integration.
The 2 A rating holds at 35 °C; at 40 °C it derates to 1.85 A, at 45 °C to 1.78 A, at 50 °C to 1.69 A, and at 55 °C to 1.61 A. If the panel runs hot, the actual continuous current the MCB can carry without nuisance tripping is lower than the nameplate — size the upstream load accordingly. Operating temperature range spans -40 °C to 75 °C, with humidity constraints: max 95% up to 55 °C, max 55% up to 70 °C, and max 35% up to 75 °C.
For a BOM line that requires this exact order code, the 2 A C-curve rating, 1-pole form factor, and 50 kA SCCR at 440 V AC confirm fit for the specified duty.
The MCB is designed for mechanical engineering and industry per its suitability designation. It is halogen-free and silicon-free, sealable, and carries an IP20 protection class with connected conductors. The combined terminal design (top and bottom) accepts standard wiring. The product designation follows EN 61346-2 and IEC 81346-2 function code F (protective device).
