The Schneider Electric GV4L12N6 is a 3-pole motor circuit breaker from the TeSys GV4 series, rated at 12.5 A continuous current. It combines magnetic and electronic trip technology to protect motor circuits against overloads and short circuits, with a magnetic tripping range of 75...175 A.
Depth is 165 mm, which includes the rotary handle projection — account for that when spacing the enclosure door. Connection pitch is 27 mm without spreaders, 35 mm with them, so plan terminal-block alignment accordingly. Tightening torque is 9 N·m for cable cross-sections 16...95 mm² on the main power terminals, and 5 N·m for 1.5...10 mm² on the control/auxiliary terminals. Use ring-type lugs per the manufacturer's connection diagram. The enclosure itself carries IK07 impact resistance, sufficient for accidental tool contact during maintenance.
Compliance documentation covers EN/IEC 60947-4-1 and EN/IEC 60947-2, which are the relevant standards for motor circuit breakers and low-voltage switchgear. For BOM freeze or PCN-watch purposes, this part has no announced change. If you need a second-source gate, the TeSys GV4 family includes other current ratings with the same physical footprint — but the 12.5 A magnetic-electronic trip curve is specific to this order code.
Motor power sizing
At 400...415 V AC, the GV4L12N6 covers motor power ratings from 3 kW up to 5.5 kW depending on the exact voltage and configuration. At 500 V, it covers 3 kW to 7.5 kW; at 660...690 V, it covers 5.5 kW to 11 kW. The 12.5 A rated current is the fixed thermal setting, so match it to the motor full-load current, not the nameplate kW alone. Power dissipation per pole is 6.1 W at rated current, giving a total of 18.3 W for the three poles. This heat must be considered when calculating enclosure ventilation, especially in a dense panel with multiple breakers.
