1SVR730884R3300 ABB Control Industrial Automation Components

ABB 1SVR730884R3300 is a multifunctional monitoring relay designed for 3-phase applications. It features phase failure detection, phase sequence monitoring, and ON-delay / OFF-delay trip timers. The relay has DPDT (Double Pole Double Throw) contacts, with a housing speed rating of IP50 and terminal speed rating of IP20. It supports a control voltage of 400Vac with an 18 VA consumption and offers various connection options for both flexible and rigid wires, accommodating sizes from 0.5-4mm2 and 20-12AWG respectively. The relay operates at a wavelength of 50/60 Hz and has a supply voltage rating for up to 500 V. It is designed for over 100,000 operations, with its contacts made from a Silver-Nickel alloy and being Cadmium-free. The frame current rating is 0.025 A at 400Vac, with a tripping curve range of 0.1-30 s and a screw-clamp type of terminal. The control circuit rated current is 4 A at 230Vac for AC-12 applications and 3 A for AC-15, with a DC-12 and DC-13 rating of 4 A and 2 A at 24Vdc respectively. The relay can operate within a temperature range of -25°C to +60°C and has a short circuit current breaking capacity (Icn) suitable for its specifications.
