S2-A2 110-415V

The ABB S2-A2 110-415V is a universal, high-quality, general-purpose electromagnetic relay from ABB's extensive range of industrial control components. It is an 8-pin (octal base), plug-in relay featuring a DPDT (Double Pole Double Throw) contact configuration. The "110-415V" suffix explicitly denotes its coil voltage range, indicating it is designed to operate reliably across a wide spectrum of AC voltages, from 110V to 415V, at 50/60 Hz.
