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.

• 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

• Marine sector
• Manufacturing industry
• Building sites

The thermistor motor protection relay can withstand 10g of mechanical shock for 11ms, making it suitable for use in vibrating systems.
