The 4-module-width (70 mm depth) footprint snaps onto standard DIN rail.
The 1 A rating with C-curve characteristic (magnetic trip at 5–10× In) means this breaker protects circuits with moderate inrush — think control transformers, small contactor coils, or instrumentation supplies — where a B-curve would nuisance-trip on startup but a D-curve would delay too long for conductor protection. Four poles let this single device switch all three phases plus neutral in a 400/230 V three-phase system, or serve as a four-wire DC isolator up to 60 V DC. The terminal range accepts solid or stranded conductors from 0.75 mm² up to 25 mm², covering everything from 1.5 mm² control wiring to 6 mm² feeder tails without adapters.
Deployment context
Ambient temperature range of -20 to +45 °C covers most indoor electrical rooms and climate-controlled enclosures; derate above 45 °C per the thermal curve in the datasheet.
