This essential safety accessory enables seamless integration with emergency stop buttons, safety relays, PLC control systems, and automated interlock loops. Designed for convenient side mounting directly onto the starter body, it features robust screw terminals for secure control wiring and reliable contact. With a rated insulation voltage ($U_i$) of $690 text{ V}$ and a wide operating temperature range from $-25^circtext{C}$ to $+60^circtext{C}$, the AA1-24 ensures dependable performance under demanding industrial plant environments.
