Product Description

The Schneider Electric GV2ME32 is the highest-rated model in the world-famous TeSys GV2 motor circuit breaker family and the definitive compact starter for 15–18.5 kW motors at 400 V. It delivers Class 10 thermal-magnetic protection, high short-circuit performance, phase-loss sensitivity and manual isolation in the same ultra-compact 45 mm width as the rest of the range. Pushbutton operation and instant DIN-rail mounting make it the perfect all-in-one solution for large pumps, compressors, fans, heavy conveyors, HVAC systems and industrial machinery.

Standard Features

  • Perfect for 15–18.5 kW motors: 24–32 A range covers the most common upper-end motors in the GV2 frame.

  • 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 needed 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.

The Schneider Electric GV3P73 is a 3‑pole motor circuit breaker from the TeSys GV3 series, designed for thermal‑magnetic protection of motors in industrial and commercial applications. Rated at 73A with an adjustable thermal protection range of 62…73A and magnetic tripping at 1120A (15×In), it delivers comprehensive overload and short‑circuit protection for motors up to 37kW at 400/415V[reference:0][reference:1]. The rotary knob provides intuitive start‑stop control with 20,000 electrical cycles endurance[reference:2]. Featuring EverLink BTR screw terminals for reliable, long‑lasting power connections, the GV3P72 is compact (55mm wide)[reference:3], supports DIN rail or panel mounting[reference:4], and is certified to IEC, UL, CSA, CCC, EAC, Marine, and ATEX standards[reference:5]. As part of the TeSys Deca family, it offers a complete motor protection solution — overload, short‑circuit, and disconnection — in a single device[reference:6].

  • Thermal‑Magnetic Protection: Adjustable thermal overload protection (62…73A) combined with magnetic short‑circuit protection at 1120A (15×In) ensures complete motor protection in a single device[reference:7][reference:8].

  • High Breaking Capacity: Delivers 50kA Icu at 400/415V AC and up to 65kA at 230/240V AC, providing robust fault current interruption for demanding industrial applications[reference:9][reference:10].

  • EverLink BTR Connection Technology: Patented EverLink screw terminals provide constant tightening pressure for reliable, long‑lasting power connections with reduced maintenance[reference:11].

  • Intuitive Rotary Knob Control: Manual start‑stop operation with a rotary knob, padlockable for safety, and guaranteed for 20,000 electrical cycles (AC‑3 @ 415V)[reference:12][reference:13].

  • Complete Motor Starter Solution: When combined with a TeSys contactor, provides a complete Type 1 or Type 2 motor starter, simplifying panel design and reducing component count[reference:14].

  • Compact & Versatile Mounting: Space‑saving 55mm width with DIN rail (35mm) or panel mounting options for flexible installation in control cabinets[reference:15][reference:16].

  • Global Approvals & Sustainability: Multi‑standards certified (IEC, UL, CSA, CCC, EAC, Marine, ATEX)[reference:17] and Green Premium compliant with a total lifecycle carbon footprint of 30 kg CO₂ eq.[reference:18][reference:19]
