Description
About the RM35TM50MW
About the RM35TM50MW
The Schneider Electric RM35TM50MW is a Harmony Series SSD1 3-phase control relay rated at 5A with a wide supply voltage range of 24–240V AC/DC, designed for reliable phase monitoring and protection in industrial automation and control panel applications. This versatile relay detects phase loss, phase imbalance, and incorrect phase sequence, safeguarding three-phase equipment from potentially damaging electrical faults. Compact and DIN-rail mountable, the RM35TM50MW is a trusted choice for engineers specifying motor and load protection solutions across diverse industrial environments.
Applications & Use Cases
- Motor Protection: Monitors three-phase supplies to detect phase loss, imbalance, or incorrect phase sequence before motors are energised, preventing winding damage and costly downtime.
- Control Panel Integration: Compact DIN-rail form factor makes the RM35TM50MW straightforward to integrate into standard industrial control panels and switchboards.
- Industrial Automation: Suitable for production lines, HVAC systems, pumping stations, and conveyor drives where reliable three-phase supply integrity is critical.
- Wide Voltage Compatibility: The 24–240V AC/DC rated voltage range allows a single relay type to cover a broad range of global supply standards, simplifying spares inventory.
