Product details

Rated 32 A at 30 °C ambient, the unit derates to 30.4 A at 40 °C, 28.8 A at 50 °C, and 24.64 A at 70 °C.

Snaps onto DIN rail (35 mm) — 2 module-widths wide at 36 mm, 77 mm deep, 90 mm tall. Mounting position is unrestricted. Halogen-free and silicon-free construction, important for clean-room or high-reliability environments where outgassing must be minimized.

Surge voltage resistance rated at 4 000 V, insulation voltage 264 V — the device withstands the impulse voltages typical of a 230/240 V TN system. Energy limitation class 3 — limits the let-through energy during a short-circuit, reducing stress on downstream wiring and connected equipment. Test voltage minimum 195 V — the integral test button for the residual-current function operates reliably down to that voltage, so periodic testing is valid even on a lightly loaded circuit.
