EATON PKZM0-20-SPI32 Motor-Protective Circuit-Breaker, 20 A, 9 kW, 3-Pole 199201

The EATON PKZM0-20-SPI32 stands out with its fixed short-circuit release at 14 times the rated current, providing dependable protection for motors up to 9 kW at 400 V. This 3-pole motor-protective circuit-breaker combines thermal and magnetic tripping in a compact DIN-rail mountable unit.

Highlights

• Rated operational current: 20 A, adjustable from 16 A to 20 A
• High breaking capacity: 50 kA at 400 V AC
• Wide voltage range: up to 690 V AC
• Thermal-magnetic release for overload and short-circuit protection
• Screw terminals for secure main circuit connections

In daily use

Set the overload release to match your motor's full-load current, and the breaker will protect against both gradual overheating and sudden short circuits. The fixed magnetic trip ensures fast response to high fault currents, reducing downtime and equipment damage.
