ABB Monitoring Relay, Thermistor Motor Protection Type, DIN Rail Mounting - CM-MSS Series - 1SVR730712R1300 CM-MSS.51S
Protect your equipment when the heat is on with this monitoring relay from ABB. Its inbuilt PTC sensor detects dangerous rises in temperature and sends a signal to de-energise the circuit, preventing your motor from overheating. The product also features short-circuit and dynamic interrupted wire detection to provide well-rounded protection against hazards. As the terminals have an IP20 rating, they're touch-proof and protected from objects larger than 12mm for safe handling. Simply clip the relay onto a DIN rail to install it in a snap without the need for any tools.
