mill-type dc relays and overloads | control relays and

Mill-type DC relays are constructed for steel panel mounting with front connections. Each unit circuit block has a two-pole double break design with captive mounting screws and are interchangeable between relays. DC overload relays are designed for use on DC power circuits to monitor DC motor loading. Inverse time limit trip relays are normally set to trip between 125% and 175% of full load motor …

mill-type limit switches | eaton - power management solutions

Mill-type limit switches. Control limit track type switches operate at 600 V maximum, ac or dc. Types of operators for these switches are roller lever (460 FPM), standard fork lever (700 FPM), heavy-duty fork lever (340 FPM) and counter, and counter weight with reset for over-hoist applications. Standard spring return switches operate in one direction only (contacts change state when lever is moved in one …
