Monitoring relay from 90-690V AC - Effective power relay AC90...690V DC0V 3UG4641-2CS20

Monitoring relay from 90-690V AC - Effective power relay AC90...690V DC0V 3UG4641-2CS20 – Siemens – 4011209665163: Monitoring relay from 90-690V AC 3UG4641-2CS20 Design of the electrical connection spring-loaded connection, rated control supply voltage Us at AC 50 Hz 90 ... 690V, rated control supply voltage Us at AC 60 Hz 90 ... 690V, rated control supply voltage Us at DC 0V, type of voltage for actuation AC, With removable terminals, rated voltage 90 ... 690V, measuring current 0.2 ... 10A, rated operating frequency 50 ... 60Hz, number of phases 1, adjustable response value for cos-phi 0.1 ... 0.99, min. adjustable response delay time 0s, max. permissible response delay time 99s, min. adjustable off-delay time 0.1s, max. permissible off-delay time 20s, number of contacts as NC contact 0, number of contacts as NO contact 0, number of contacts as changeover contact 2, width 22.5mm, Height 103mm, depth 91mm, digital monitoring relay cos-phi and current monitoring from 90-690 V AC overshoot and undershoot self-supplied AC 50 to 60Hz interference peak delay 0.1 to 20 s hyste rese at (I) 0.1 to 2 A 2 changeover contacts with or without fault memory Spring-loaded technology Digitally adjustable cos phi monitoring relay SIRIUS 3UG4 for monitoring the power factor and active current for exceeding, e.g. B. with dirty filter systems, or falls below, z. B. in the event of a V-belt tear or pump idling. Worldwide use thanks to wide range and international certificates. The relay also monitors smaller single-phase motors with no-load current below 0.5 A. Implicit monitoring for wire breakage and phase failure is possible. The measuring principle cos phi or active current can be selected. Less space required in the control cabinet thanks to a narrow overall width. Reliable diagnosis by displaying the actual value and status messages. All versions with removable connection terminals. In addition to screw connection technology, the devices are also available with spring-loaded connections for a quick, maintenance-free and vibration-proof connection. They are optionally available with IO-Link. The comprehensive range of accessories, such as device identification labels, push-in lugs and cover caps, is the same for all relays. SIRIUS relays - a program for all cases.
