Couldn't load pickup availability
The Schneider Electric GV3P73 is a TeSys GV3 thermal-magnetic motor circuit breaker with a setting range of 62–73 A. It protects three-phase motors against overload, short circuit and phase failure, and can also be used to start and stop the motor manually – replacing a breaker plus overload relay in one compact unit.
Key features
- Adjustable thermal setting 62–73 A to match the motor nameplate current
- Phase-failure sensitivity for three-phase motors
- Clear ON/OFF/TRIP indication and lockable handle for safe maintenance
- Direct mounting with TeSys contactors to build compact starters
- Accepts auxiliary contacts, fault signalling contacts and undervoltage releases
- DIN-rail or panel mounting

Selection guide
Select the range so that the motor full-load current (from the nameplate) falls inside the setting range, then set the dial exactly to the nameplate current. For example, a 7.5 kW 400 V motor draws about 15 A, so a 13–18 A range is appropriate.
Frequently asked questions
What motor size suits the GV3P73?
With a 62–73 A setting range it suits three-phase motors whose full-load current lies within that range – roughly up to 37 kW at 400 V.
Do I need an overload relay with this breaker?
No for thermal-magnetic GV2ME/GV2P/GV3P/GZ1E types, which include overload protection. Yes for magnetic-only GV2L types, which must be combined with a thermal overload relay.
