Product FAQs
8 answersWhich auxiliary contact blocks are compatible with the GV3P25?
This breaker accepts TeSys GV accessories, including the GVAE11 for front-mounted auxiliary contacts or the GVAN11 for side-mounted signaling.
What are the compatible contactors for building a motor starter with this breaker?
The GV3P25 pairs directly with TeSys Deca contactors, specifically the LC1D25 and LC1D32 models, to build a complete Type 1 or Type 2 motor starter assembly.
What is the magnetic trip current setting?
The fixed instantaneous magnetic trip is factory set at 350 Amps, which is 14 times the maximum rated thermal current, ensuring rapid short-circuit clearance.
What is the maximum 3-phase horsepower rating for this breaker at 480V?
The GV3P25 supports up to 15 HP at 480VAC and up to 20 HP at 600VAC for 3-phase motor applications.
Can this 3-pole breaker be used for single-phase motors?
Yes, it can protect single-phase motors when wired correctly and is rated for up to 1.5 HP at 115VAC and 3 HP at 230VAC.
How do the terminals secure the wiring on this device?
It utilizes EverLink BTR screw clamp terminals, which provide constant tightening pressure to prevent wires from loosening due to thermal cycling or vibration.
How is the breaker secured inside an electrical enclosure?
The compact 55mm wide GV3 frame snaps directly onto a standard 35mm DIN rail for quick panel mounting.
How does the rotary operator indicate a fault?
When a fault occurs, the rotary knob automatically moves to a distinct Trip position. The knob can also be padlocked in the Off position for secure lockout/tagout (LOTO) procedures during maintenance.
