45 Presentation protection components Thermal-magnetic motor circuit-breakers GV, GV and GV7 O GV ME I 4 O GV ME I 4 GV ME, GV P, GV ME and GV7 R motor circuit-breakers are -pole thermalmagnetic circuit-breakers specifically designed for the control and protection of motors, conforming to standards IEC and IEC Connection These circuit-breakers are designed for connection by screw clamp terminals. Circuit-breaker GV ME can be supplied with spring terminal connections. These ensure secure, permanent and durable clamping that is resistant to harsh environments, vibration and impact and is even more effective when conductors without cable ends are used. Each connection can take two independent conductors. GV P 4 GV7 R O Operation Control is manual and local when the motor circuit-breaker is used on its own. Control is automatic and remote when it is associated with a contactor. GV ME and GV ME 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. GV P Control by rotary knob GV ME with screw clamp connections GV P GV ME with spring terminal connections GV ME GV7 R Control by rocker lever. Energisation is controlled manually by moving the knob or rocker lever to position I. De-energisation is controlled manually by moving the knob or rocker lever to position O. De-energisation due to a fault automatically places the knob or rocker lever in the Trip position. Re-energisation is possible only after having returned the knob or rocker switch to position O. Protection of motors and personnel Motor protection is provided by the thermal-magnetic protection elements incorporated in the motor circuit-breaker. The magnetic elements (short-circuit protection) have a non-adjustable tripping threshold, which is equal to about times the maximum setting current of the thermal trips. The thermal elements (overload protection) include automatic compensation for ambient temperature variations. The rated operational current of the motor is displayed by means of a graduated knob 4. Personnel protection is also provided. All live parts are protected against direct finger contact. The addition of an undervoltage trip allows the circuit-breaker to be de-energised in the event of an undervoltage condition. The user is therefore protected against sudden starting of the machine when normal voltage is restored, since the Start button I has to be pressed to restart the motor. With the addition of a shunt trip, de-energisation of the unit can be remotely controlled. The operators on both open-mounted and enclosed motor circuit-breakers can be locked in the Stop position O by up to padlocks. Because they are suitable for isolation, these circuit-breakers, in the open position, provide an adequate isolation distance and indicate the actual position of the moving contacts by the position of the operators. GV7 R Special features These motor circuit-breakers are easily installed in any configuration thanks to their universal fixing arrangement: screw fixing or clip-on mounting on symmetrical, asymmetrical or combination rails.

Description Type Degree of protection Reference Weight kg Direct rotary handle Black handle, black legend plate IP 40 GV7 AP Red handle, yellow legend plate IP 40 GV7 AP Adapter plate () Four mounting direct rotary handle on enclosure door IP 4 GV7 AP05 0. Extended rotary handle Allows a circuit-breaker installed in the back of an enclosure to be operated from the front of the enclosure. It comprises: b a unit which replaces the circuit-breaker front cover; secured by screws, b an assembly (handle and front plate) to be fitted on the enclosure door, b an extension shaft which must be adjusted (distance between the mounting surface and the door: 85 mm minimum, 600 mm maximum). It includes a device for locking the circuit-breaker in the "O" (Off) position by means of up to padlocks with a shank diameter of 5 to 8 mm (padlocks not supplied). This prevents the enclosure door from being opened.

77 Presentation, selection Protection components Thermal-magnetic circuit-breakers GB for the protection of industrial equipment control circuits Presentation GB thermal-magnetic circuit-breakers protect and isolate the control circuits of industrial equipment with contactor coils, transformers. They protect and isolate single-phase auxiliary circuits such as solenoid valves, electro-brakes, battery chargers, supplied from the control circuit voltage. GB CB, GB CD, GB DB ratings are available, from 0.5 to 0 A, in single-pole (GB CB), single-pole + neutral (GB CD) and -pole (GB DB) versions. They have a magnetic tripping threshold set at between and 6 In to withstand the current peaks generated by many industrial components. GB CS ratings are available, 0.5 and A, in single-pole version. The magnetic tripping threshold is set between 5 and 7 In. Functions, installation Clip-on fixing onto all types of 5 mm 5 rails, on 4 rails and on Telequick mounting plates. Upstream and downstream marking by means of AB clip-in markers. Clear indication of I and O positions on the operator. Tamper-proof device which requires no special maintenance (fixed magnetic and thermal tripping thresholds). Selection for the protection of circuits supplied by transformers Single-phase transformers. Magnetising peak: 0 In. Operation of magnetic trips: In.
