Current monitoring relay 8...80A 3RR2143-3AA30

Current monitoring relay 8...80A 3RR2143-3AA30 – Siemens – 4011209937802: Current monitoring relay 24-240V 3RR2143-3AA30 Design of the electrical connection Screw connection, With removable terminals, Rated control supply voltage Us at AC 50 Hz 24 ... 24V, Rated control supply voltage Us at AC 60 Hz 24 ... 24V, Rated control supply voltage Us at DC 24 ... 24V , type of voltage for actuation AC/DC, current measuring range 8 ... 80A, min. adjustable response delay time 0s, max. permissible response delay time 60s, min. adjustable off-delay time 0s, max. permissible off-delay time 30s, width 55mm, height 99mm, depth 112mm, monitoring relay, Can be mounted on 3RT2 contactor, size S2 Basic, analog adjustable Apparent current monitoring 8...80 A, 50...60 Hz, 2-phase Supply 24 V AC/DC 1 changeover contact Monitoring for current overshoot and undershoot, phase failure, wire break with or without error memory Start-up delay 0-60 s Interference peak suppression 0-30 s Switching hysteresis 6% Spring-loaded technology SIRIUS 3RR2 monitoring relay for plugging into the contactor e SIRIUS 3RT2 or for individual installation for multi-phase current monitoring of the entire system or the driven process. Reliable monitoring for cable breaks, phase failure, phase sequence, residual current, motor blocking and much more. creates increased system availability. Actual value displays, status messages and clear error messages enable fast and reliable diagnosis. The control connection via IO-Link is also possible. You also save on costs as only one device is required to monitor a motor along the entire torque curve and separate current transformers are also not required. Due to the direct attachment to the 3RT2 contactors, there is no additional wiring effort in the main circuit. You can also benefit from the wide-voltage power supply units for worldwide use. Analog adjustable, 2-phase versions and digitally adjustable, 3-phase versions (with and without IO-Link) are available, each in three sizes with different current measuring ranges, with two different supply voltages and two connection types. Suitable supports are available for the individual installation of the 3RR2 monitoring relays. SIRIUS relays - a program for all cases.
