ABB Monitoring Relay, NO/NC Contacts, 300V AC Operational Voltage - CM-MSS Series - 1SVR730712R1400 CM-MSS.31S
Use this thermistor monitoring relay from ABB to prevent your motor from overheating. It performs short-circuit detection, dynamic interrupted wire detection and non-volatile fault storage functions to ensure your motor operates efficiently. Its 3 LEDs display the unit's status, so you can use them to monitor the device and evaluate load control. This relay functions in a temperature range of -25°C and +60°C, meaning it's suitable for use in demanding conditions. It's designed with a safety barrier between its supply, measuring and output circuits for effective fault isolation and detection.
Features & Benefits
• Impulse withstand voltage of 4kV to protect its components against power surges • Compatible with DIN rail mounting, so installation is quick and doesn't call for specialist tools • 300V AC operational voltage, so it's ideal for use in medium-duty to heavy-duty applications
Applications
• Marine sector • Manufacturing industry • Building sites
What level of mechanical shock can this relay handle?
