Thermal-magnetic motor circuit breaker GV2ME08

Model: 003.002.057
Thermal-magnetic motor circuit breaker GV2ME08
Manufacturer: Schneider Electric
Barcode: 3389110343090
GV2ME are three-pole thermal-magnetic circuit breakers specifically designed for the control and protection of motors, conforming to standards IEC 60947-2 and IEC 60947-4-1.
GV2ME circuit breakers are designed for connection by screw clamp terminals. They can be supplied with spring terminal connections which ensure secure, permanent and durable clamping that is resistant to harsh environments, vibration and impact and are even more effective when conductors without cable ends are used. Each connection can take two independent conductors.
Pushbutton control. Energisation is controlled manually by operating the start button "I". De-energisation is controlled manually by operating the stop button "O", or automatically by the thermal-magnetic protection elements or by a voltage trip attachment.
