The Schneider Electric A9C15507 is an Acti9 TL impulse relay — a 2-pole, 16 A rated device controlled by a 230 V AC 50 Hz impulse signal, designed for remote and manual switching of lighting or resistive loads in commercial and industrial final distribution boards. Compliance with IEC 60669-2-2 and IEC 60669-1 confirms it meets the international standard for electronic switches in household and similar fixed electrical installations, making it a defensible choice for tender specifications that require third-party certification.
The 16 A rated current (In) and 250 V AC operational voltage (Ue) define the maximum continuous load this relay can switch — sized for lighting circuits up to 4 kW on a 230 V line, or resistive heating loads within that envelope. Electrical durability is rated at 200,000 cycles under AC-22 duty (mixed resistive and inductive loads), which is the relevant endurance figure for lighting contactor applications — not the mechanical life, but the cycles it can deliver while switching rated current. The impulse control signal requires a 3 mA illuminated push-button or equivalent pulse source; the relay latches mechanically on each pulse, so the control wire need only carry a brief 50 ms pulse, not a continuous hold signal. Pollution degree 3 rating means the relay is designed for environments with conductive or dry non-conductive pollution — typical of control panels in industrial halls where some dust and humidity are present, but not direct washdown.
For audit purposes, the manufacturer provides compliance documentation covering the IEC standards cited on the nameplate; the NF quality label further confirms conformity to French national standards, which may be required for public-sector tenders in that jurisdiction.
Terminals are tunnel type: power circuit accepts 1 to 4 mm² rigid or flexible (single cable) or 2 × 1 to 2.5 mm² (two cables); control circuit accepts 0.5 to 1.5 mm². Strip length is 9 mm, tightening torque 1 N·m — standard for a 16 A class relay. Dimensions are 18 mm wide × 84 mm high × 60 mm deep, so it occupies one DIN-rail module and leaves clearance for wiring ducts or adjacent devices in a standard 60 mm deep enclosure. Operating temperature range is -20 to 50 °C, storage -40 to 80 °C, with 95% relative humidity at 55 °C — adequate for unconditioned electrical rooms but not for outdoor installation without a weatherproof enclosure.
