1SVR550870R9400 ABB Control Industrial Automation Components

ABB 1SVR550870R9400 is a control relay designed for phase failure, under-/over-voltage, and neutral monitoring for both single-phase and 3-phase systems with fixed thresholds. It features 1 Normally Open (NO) auxiliary contact and offers protection functions at a rated insulation voltage (Ui) of 400 V. The housing is rated IP50, and the terminals are rated IP20, ensuring a degree of protection against dust and touch. It supports a control voltage for DIN rail mounting and accommodates various wire types and sizes for connection, including flexible wire with ferrule, flexible wire, and rigid wire ranging from 0.75-1.5mm2 to 18-16AWG. The relay operates at a frequency of 50/60 Hz, with a supply voltage indicating durability for 100,000 operations. It has a rated voltage (AC) for phase-to-phase connections at 265 V and is designed for a control circuit rated current of 4 A at 230Vac for AC-12 and 3 A at 230Vac for AC-15, with a DC-12 and DC-13 rating of 4 A and 2 A at 24Vdc, respectively. The operating temperature ranges from -20°C to +60°C, and it features a yellow LED indicator for relay energization status. The trip unit type is a screw-clamp for secure connections, and it is designed to handle short circuit current breaking capacity (Icn) efficiently. The measurement function covers operating voltages from 320-460Vac (L-L) and 185-265Vac (L-N), ensuring comprehensive monitoring and control capabilities.
