Press Release Summary:
Series WMS thermal-magnetic devices are UL1077 recognized for applications where branch circuit protection is not required or is already provided. DIN-rail mounted units come in 1- and 3-pole configurations. B-curve models trip at 3-5 times rated current for low-inrush type loads, while D-curve models trip at 10-20 times rated current for high-inrush inductive loads. Shunt trips are available for remotely tripping protector with external voltage.

AutomationDirect® Adds Supplementary Protectors to Product Line
Cumming, GA --- February 15, 2004 --- AutomationDirect® is now offering Cutler-Hammer supplementary circuit protectors by Eaton Electrical, a world leader in circuit protection. The WMS Series protectors are UL1077 recognized for applications where branch circuit protection is not required or is already provided. These thermal magnetic devices protect against short circuit and overload conditions.
The WMS Series protectors are DIN-rail mounted and come in one- and three-pole configurations. They are available in two trip curves. The B-curve trips at three to five times the rated current and is typically used for PLCs, industrial computers, and low inrush type loads. The D-curve trips at 10 to 20 times the rated cunent for higher inrush inductive loads like transformers and motors. Shunt trips are available for remotely tripping the protector with an external voltage from a control system or alarm device.
A padlocking feature is also available for preventing unauthorized operation. Maintenance personnel can
safely work on protected equipment without electrical safety concerns. The WMS Series protectors are priced at $7 for a single-pole device, regardless of current rating or trip curve. The triple-pole devices are priced at $20.
