Clip-on mounting on DIN rail. The bottom screw-clamp terminals accept 0.75-2.5 mm² rigid or flexible wire, with a strip length of 6 mm and tightening torque of 0.6 N·m. The 1 NC signal contact provides a remote indication that the release has operated — wire it into the PLC or alarm circuit.
Designed to EN/IEC 60947-2, the standard for circuit-breaker accessories. Operating temperature range -5 to 55 °C, storage -40 to 70 °C.
The control circuit accepts 110-400 V AC 50 Hz or 110 V DC. The threshold tripping voltage is 0.7 to 1.1 times the nominal control voltage.
The A9A19805 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The part is designed to EN/IEC 60947-2 and carries pollution degree 2 and overvoltage category III ratings. For RoHS, REACH, and UL documentation, request the manufacturer's declaration of compliance with your RFQ.
