Product FAQs
7 answersWhat is the difference between the GV2P08 and the GV2ME08?
Both are 2.5 to 4A thermal-magnetic motor protection circuit breakers in the TeSys GV2 series. The GV2P08 features a rotary handle operator and offers higher short-circuit breaking capacity, while the GV2ME08 uses pushbutton controls.
What is the fixed magnetic tripping current for the GV2P08?
The magnetic trip threshold for this breaker is factory set at 51A. The thermal overload protection remains adjustable between 2.5A and 4A to match your motor full-load amp rating.
Which auxiliary contact blocks are compatible with the GV2P08?
This motor circuit breaker accepts standard TeSys GV2 auxiliary contacts, including the front-mounted GVAE11 and the side-mounted GVAN11 blocks, for signaling and control integration.
Can I mount the GV2P08 directly to a contactor?
Yes, you can pair this breaker with a Schneider Electric TeSys Deca contactor, such as the LC1D series, using a GV2AF combination block to create a complete, compact motor starter assembly.
What size motor is the 2.5 to 4A GV2P08 typically used to protect?
When applied at 400V or 415V AC, this breaker is commonly used to protect 3-phase motors rated around 1.1 kW to 1.5 kW. Always verify your specific motor nameplate full-load amperage falls within the 2.5 to 4A adjustment range.
Can the GV2P08 be used as a UL 508 Type E self-protected combination motor starter?
Yes, the GV2P series carries a UL 508 Type E rating when installed with the required GV2GH7 line-side insulating barrier.
Does the GV2P08 provide visible trip indication and isolation?
Yes, the rotary handle on the GV2P08 provides clear mechanical trip indication by moving to a distinct tripped position when a fault occurs. The handle is also lockable to ensure safe isolation for lockout procedures during maintenance.
