ABB 1SVR740794R3300 Automation & Control Systems - UL/CSA
Part Number: 1SVR740794R3300
Quick Summary
1SVR740794R3300 is a three-phase monitoring relay for protection and supervision in electrical distribution and automation systems. Many engineers contend with undetected phase faults and misadjusted thresholds, so this device provides adjustable threshold values, a selectable phase sequence monitor, and an ON/OFF tripping delay to fit specific protection schemes. It carries CE, UL/CSA, and UKCA declarations for global compliance, with CAN/CSA certification and IEC/EN 61000 series compatibility for robust industrial performance. Its Easy Connect technology with push-in terminals simplifies installation, while screw-terminal compatibility and a compact 22.5 mm width help save DIN rail space. In practice, it reduces misoperations, improves safety margins, and supports scalable protection schemes in panel builds.

Measuring range and protection thresholds drive reliability. The device monitors (L-L) 300-500 V AC with adjustable over- and undervoltage thresholds, plus phase failure detection and phase sequence monitoring. The business impact is precise fault detection and reduced nuisance trips in motors and drives, enabling safer, more reliable panel operation in packaging lines, metalworking, or process plants. Output and switching deliver 2 c/o SPDT contacts rated up to 4 A at 230 V, providing clean control signals for interlocking, alarms, and protective interlocks in starter circuits and logic networks. Installation and mounting maximize efficiency with a 22.5 mm width on DIN rails TH35-15 or TH35-7.5 and Easy Connect push-in terminals, reducing wiring time and miswiring risk. Durability and safety are addressed by IP50 housing, 600 V insulation, 4 kV impulse withstand, and a wide operating range of -25 to +60 °C, enabling reliable operation in harsh industrial environments. Compliance and lifecycle considerations are supported by RoHS/REACH, CE/UL/CSA approvals, and DNV GL/UL 508 references, ensuring future-proof panel integration and reduced total cost of ownership. Industry context notes that these relays are well-suited for motor protection, redundant signaling, and complex sequencing in automation and process control applications, delivering predictable protection curves and scalable monitoring architecture.

FAQs
The 1SVR740794R3300 fits standard DIN rails TH35-15 and TH35-7.5 and uses screwless push-in terminals for easy, secure wiring. This design reduces field wiring time and minimizes terminal loosening, making it ideal for compact panel layouts and high-vibration environments common in automation facilities.
It delivers phase failure detection, phase sequence monitoring, and over- and undervoltage monitoring in the range of 300–500 VAC, with adjustable thresholds and an ON/OFF tripping delay (0, 0.1–30 s). These features support reliable protection of motors, transformers, and drives against improper phase conditions.
The device is specified for AC control and measurement circuits (L-L 300–500 VAC). While the relay outputs are SPDT contacts suitable for AC control applications, DC control signals should be evaluated against the specific system requirements and the device’s DC ratings listed in the datasheet.
Key certifications include CE, UL/CSA, CAN/CSA, and UKCA with compliance to IEC/EN 61000-6-2 and 61000-6-3. Additional references include UL 508, EN 63000, and RoHS/REACH declarations, along with SCIP registration, supporting global deployment in safety-critical industrial environments.
Easy Connect combines push-in terminals with maintenance-free operation, reducing wiring errors and time on site. A sealable cover option protects configurations from tampering, and the compact form factor plus DIN rail compatibility simplify retrofits and upgrades in existing automation panels.
