Supplied by Ahmedabad Electric Corporation, the ABB UA1-415 is a side-mounting undervoltage release unit engineered for fail-safe protection and emergency tripping of ABB Manual Motor Starters (including MS116, MS132, and MS165 series). Designed to operate on high-voltage control circuits at $415text{ V}$ at $50text{ Hz}$ and $480text{ V}$ at $60text{ Hz}$, the UA1-415 automatically disconnects the connected manual motor starter whenever the control supply voltage drops below safe operating limits. This essential safety protection prevents hazardous, accidental motor auto-restarting when main power is restored after a voltage failure or power outage. Featuring a quick-fitting side-mounting design directly onto the manual motor starter frame, the UA1-415 includes durable screw terminals for secure electrical connections. Constructed with a rated insulation voltage ($U_i$) of $690text{ V}$ and an operating temperature range from $-25^circtext{C}$ to $+60^circtext{C}$, this component delivers reliable undervoltage trip performance across demanding industrial control panel environments.
