37 kW / 50 hp VFD for asynchronous motors
The ATV212HD37N4LCD is a 37 kW (50 hp) Altivar 212 AC drive designed for asynchronous motors, with a line current of 54.4 A at 480 V and 68.9 A at 380 V. It delivers 52 kVA apparent power at 380 V and covers a speed range of 1 to 10, with an adjustable PI regulator loop for process control.
Panel fit and mounting constraints
The drive measures 550 mm high, 240 mm wide, and 244 mm deep — the 240 mm width is the critical dimension for DIN-rail or backplate spacing in a standard 600 mm enclosure. Mount vertically within ±10° of upright, with 100 mm clearance above and below for the 334 m³/h forced-air flow through the heatsink. Operating altitude is 1000 m without derating; above that, derate 1 % per 100 m up to 3000 m, with a 2000 m limit on corner-grounded distribution networks.
Protection and compliance package
The drive includes integrated Class C2 EMC filter and meets IEC 61800-3 environments 1 and 2 categories C1 through C3, plus EN 55011 Class A Group 1 and UL Type 1. Protection covers overheating, short-circuit between motor phases, earth faults, DC bus overvoltage, input phase loss, motor thermal protection, and PTC probe input. Pollution degree 3 per IEC 61800-5-1, shock resistance 15 gn for 11 ms, and humidity range 5 to 95 % without condensation.
Sourcing and lifecycle status
No official successor or pin-compatible alternative is recorded; confirm fit by matching the 37 kW / 50 hp rating, 480 V input, and the 550 x 240 x 244 mm footprint.
