The GV4PE80B6 is a 3-pole motor circuit breaker from the TeSys Deca range, rated 80 A line current and built for continuous motor protection duty per IEC 60947-4-1. That 80 A rating sets the thermal overload threshold — the breaker holds continuously at 80 A and trips on sustained overcurrent above that level, protecting the motor winding without nuisance tripping on normal starting inrush. The electronic thermal-magnetic trip unit combines two protection modes: an electronic thermal element that tracks motor heating with an adjustable time curve, and a fixed magnetic trip set at 1360 A for short-circuit protection. Phase failure sensitivity per IEC 60947-4-1 means the breaker detects a lost phase and trips before single-phasing damages the motor — no separate phase-loss relay needed. Under UL 60947, the SCCR is 35 kA at 240 V and 18 kA at 480Y/277 V. These numbers govern your coordination study — the breaker must clear a fault within its rated interrupting capacity without upstream devices having to open.
Isolation and lockout — rated for safe de-energization
The GV4PE80B6 is certified suitable for isolation per IEC 60947-1. That means when the toggle is in the OFF position, the contacts provide a visible air gap that meets the isolation standard — you can positively disconnect the motor for maintenance and lock the toggle. No exceptions: if it's not locked, it's not safe. The toggle control type supports padlock hasp attachment for LOTO compliance.
Certifications and compliance — UL, CSA, IEC on the nameplate
That covers North American and European installations from a single part number — no dual-stock needed for a machine shipping to both markets. The fire resistance rating is 960 °C per IEC 60695-2-11, so it passes the glow-wire test for unattended equipment.
