Eaton Cutler-Hammer PKZM0-20 Motor Protector
The Eaton Cutler-Hammer PKZM0-20 is a manual motor protector designed for precise motor starter control and short-circuit protection in demanding industrial environments. This Class 10 trip device features a calibrated bimetallic thermal-trip element and a fixed high-current magnetic-trip element, making it an essential component for branch circuit protection. Engineered for three-phase motor protection, the PKZM0-20 handles 20 Amps and is built to the IEC/EN 60947-4-1 standard, ensuring reliable performance in motor control centers and isolated machinery. Contractors rely on this unit for its space-saving 45mm frame and its ability to function as a rotary manual motor controller with a clear trip indication. By integrating overload protection and a disconnect function in a single housing, this 20A motor protector streamlines DIN-rail installations while reducing wiring complexity in HVACR control panels.
- Phase Loss Sensitivity: Advanced thermal-magnetic sensing detects unbalanced loads to prevent motor winding damage.
- High Interrupting Capacity: Provides robust current limiting performance to safeguard downstream components during fault conditions.
- Accessory Compatibility: Modular design allows for the seamless integration of auxiliary contacts and shunt trips for remote monitoring.
- Compact Form Factor: Standard 45mm width optimizes panel space, allowing for more dense configurations in complex electrical enclosures.
Commonly Asked Questions
What is the maximum horsepower rating for this unit at 480V?
The PKZM0-20 typically supports up to 10 HP at 460/480VAC for three-phase applications, though always verify specific motor nameplate data for full-load amperage compliance.
Can the PKZM0-20 be used as an At-Motor disconnect?
Yes, it is UL 508 listed for use as a manual motor controller and is suitable for motor disconnect applications when paired with specific accessories to meet local codes.
Does this unit require a separate upstream fuse?
The PKZM0-20 is designed to provide short-circuit protection, but depending on the specific application and SCCR requirements, an upstream fuse or circuit breaker may be required per NEC guidelines.
