Motor protection relay

SEL-749 protects against nuisance trips while enabling maximum motor horsepower. Relay protects motors from locked rotor, running overload, and negative sequence current imbalance by accurately tracking the heating effects of load and current while the motor is accelerating and running. Relay protects against high fault-current conditions when CT is saturated.

Split CT

Split core transducers allow easy assembly and greater retrofit applications because they can be installed without causing equipment downtime. The latch, which splits the core, opens to allow installation, and secures conductors when closed can accommodate conductors up to 1.21 inches in diameter. CT models include true RMS, loop powered, self powered, average RMS, and dc current, and are available with 0—5 V dc or 4—20 mA dc output options.

Switch disconnects

SD1 series nonfused disconnects allow breaking and disconnecting on equipment loads of up to 600 V ac at a nominal current range from 16—40 A. SD2 series allows breaking and disconnecting from 63—125 A for the same voltage range. Both series are DIN rail or panel mountable and feature high breaking capacity double-break contacts, high electrical and mechanical endurance, and are resistant to damp heat.

E-Stop push-button

PITestop emergency stop push-button is designed with a safety contact block that prevents contact elements on the device without detection. Black ring at the actuator base makes it easy to detect when the e-stop has been operated — even from a distance. The mushroom-type push-buttons are designed to IP65 and are turn-to-release devices — either clockwise or counter-clockwise. A key-release version is also available.
