Current monitoring relay screw connection 3RR2443-1AA40

Current monitoring relay screw connection 3RR2443-1AA40 – Siemens – 4011209936263: Current monitoring relay screw connection 3RR2443-1AA40 Design of the electrical connection screw connection, with removable terminals, 3-phase undercurrent possible, 3-phase overcurrent possible, rated control supply voltage Us at DC 24 ... 24V, type of voltage for actuation DC, current measuring range 8 ... 80A , Min. adjustable response delay time 0s, max. permissible response delay time 999.9s, min. adjustable off-delay time 0s, max. permissible off-delay time 999.9s, width 55mm, height 99mm, depth 112mm, current monitoring relay for IO-Link, attachable to contactor, 3RT2, Size S2 Apparent/active current monitoring 8-80 A, 20-400 Hz, 3-phase Supply voltage DC 24 V 1 changeover contact Monitoring for current overshoot and undershoot Current asymmetry Phase failure, wire break Phase sequence, fault current Blocking current, switching cycle and operating hours counter Warning and alarm thresholds AUTO or HANDRESET start-up delay 0-9999.9 s switch-off delay 0-9999.9 s switch-on delay. 0-300 min Screw connection technology SIRIUS 3RR2 monitoring relay for plugging into SIRIUS 3RT2 contactors 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.
