Product FAQs
6 answersHow do the EverLink BTR screw terminals on the GV3P32 improve installation reliability?
The EverLink terminal technology features a creep-compensating spring system that maintains constant tightening pressure on bare conductors. This prevents connection loosening over time due to thermal cycling or copper compression, eliminating the need for periodic retightening in high-vibration motor control panels.
What is the maximum 3-phase motor horsepower rating for this circuit breaker at 480V?
The GV3P32 manual motor starter supports up to 20 HP for 3-phase motor applications at 480 VAC. The thermal trip dial is adjustable between 23 and 32 amps to precisely match the full-load amp (FLA) rating of the connected motor.
What is the fixed magnetic tripping current for the GV3P32?
The instantaneous magnetic trip threshold is factory-set at 448 amps. This provides immediate short-circuit protection at exactly 14 times the maximum 32A continuous current rating.
Which auxiliary contacts and trip units are compatible with the GV3P32?
This motor protection circuit breaker accepts TeSys GV3 accessories, including GVAE, GVAN, and GVAD auxiliary contact blocks for status signaling. It also supports GVAU undervoltage trip units and GVAS shunt trips for remote control and safety interlocking.
Which contactors pair directly with the GV3P32 for a complete motor starter assembly?
The GV3P32 integrates seamlessly with Schneider Electric TeSys Deca contactors, specifically the LC1D40A through LC1D73A sizes. They can be joined to build compact Type 1 or Type 2 coordinated motor starters.
Can the rotary handle on the GV3P32 be padlocked for lockout/tagout (LOTO) procedures?
Yes, the front rotary knob can be padlocked in the OFF position. This ensures reliable physical isolation of the downstream motor circuit during maintenance, supporting facility safety and standard LOTO compliance.
