ABB 1SVR450331R0000 CM-LWN Motor Load Monitor Relay

Description

• The ABB 1SVR450331R0000 belongs to the CM motor load monitors range and is a versatile relay designed to monitor and protect single- or three-phase asynchronous motors (squirrel cage). This relay operates with a rated control supply voltage of 220-240 V AC, making it compatible with a wide range of electrical systems.

• At its core, the CM-LWN relay operates based on the closed-circuit principle, ensuring precise and reliable motor load monitoring. It employs a measuring principle that evaluates the phase shift between the voltage and current in one phase of the motor. This measurement is vital for assessing the motor's performance and ensuring it operates within safe parameters.

• The measuring circuit of the CM-LWN relay is engineered to handle voltages ranging from 110 to 500 V AC and currents in the range of 0.5 to 5 A AC. This wide measurement range makes it suitable for various motor applications, allowing for flexibility in motor monitoring.
