The ABB 1SVR730824R9300 is a reliable CM-PFS.S three-phase monitoring relay designed to protect industrial equipment by continuously monitoring three-phase electrical networks for phase failure and incorrect phase sequence. This compact monitoring relay provides dependable protection for motors, machines and automation systems where uninterrupted three-phase power quality is essential.
Part of the ABB CM three-phase monitoring relay family, the 1SVR730824R9300 detects phase loss and phase sequence faults using a robust monitoring circuit. When an electrical fault is detected, the output relays de-energise, providing a reliable signal for shutdown circuits, alarms and industrial control systems.
The ABB 1SVR730824R9300 operates with a three-phase 200–500 V AC measuring supply and includes two changeover (2 C/O) relay outputs rated at 250 V / 4 A. Its compact DIN rail mounting design makes it suitable for electrical panels, machine control cabinets and industrial automation installations.
Three-phase monitoring relays such as the ABB 1SVR730824R9300 help prevent damage caused by phase loss, phase reversal and incorrect power conditions. By detecting electrical faults before they affect equipment operation, these relays improve system safety and reduce unexpected downtime.
The CM-PFS.S relay is designed for industrial automation environments where dependable monitoring, fast fault detection and simple installation are required. Its compact DIN rail format allows easy integration into control panels and switchboards.
