Product Description

The Schneider Electric GV2ME21 is the world’s most popular motor circuit breaker for 11–15 kW motors at 400 V — the absolute standard for high-power compact starters. Part of the legendary TeSys GV2 series, it provides Class 10 thermal-magnetic protection, high short-circuit performance, phase-loss sensitivity and manual isolation in a single ultra-compact 45 mm unit. Pushbutton operation and instant DIN-rail mounting make it the perfect all-in-one solution for pumps, fans, compressors, large conveyors, HVAC systems and heavy industrial motors.

Standard Features

  • Perfect for 11–15 kW motors: 17–23 A range covers the most common 400 V motors in this power class worldwide.

  • 50 kA breaking capacity: Excellent short-circuit performance — safe in nearly all industrial networks.

  • Pushbutton manual control: Direct ON/OFF + clear trip indication — no separate contactor required for basic DOL.

  • Phase failure protection: Built-in differential thermal trip automatically protects against single-phasing.

  • Full add-on compatibility: Accepts all GV2/GV3 auxiliary contacts, under-voltage/shunt trips, rotary handles.

  • Global certifications: UL 60947-4-1 Type E, CSA, CE, CCC, Marine — accepted everywhere.
