Rated operational current is 25 A in AC-7A category (resistive loads like heating) and 8.5 A in AC-7B (lightly inductive loads such as small motors). The coil pulls 230 V AC at 50 Hz, with inrush of 15 VA and hold-in consumption of 3.8 VA — a steady 3 W at 250 V AC once sealed. Switching frequency is rated at 100 operations per day, which suits periodic on/off control rather than high-cycle PWM.
The 18 mm width matches a standard modular device footprint, so it slots into a row of MCBs or RCBOs without wasting panel space. Terminals are tunnel type: power circuit accepts up to 6 mm² rigid or 2 x 2.5 mm² flexible; control circuit accepts 2 x 2.5 mm² flexible or 2 x 1.5 mm² rigid. Strip length is 10 mm; tighten to 0.8 N·m. IP20 on the body (finger-safe) and IP40 in a modular enclosure — fine for dry indoor panels. Pollution degree 2 (non-conductive dust only).
