Crane motor protection

April 2015 Operator Interfaces, Switches & Relays

Hard-working crane motors are designed for specific duty cycles, generally of short duration and in harsh environments. NewElec’s 330M crane motor protection relay is uniquely designed for each motor, providing overload, phase loss and phase unbalance protection. A motor thermal indicator meter can be fitted inside the crane operator’s cabin as a working aid to ensure that the crane is never operated beyond its loading limits.

The protection relay is selected to suit the CDF of the protected motor and provides accurate overload and unbalance protection on full RMS loading.

Latched trip LEDs indicate overload and unbalance detection and trip, with a separate trip and thermal lock-out period in process indication. Available for chassis or flush door mount, the relay has a test facility and may be fitted with a manual or automatic reset facility. A thermal trip state indicator is also available as an extra option.
