Overview
The Cutler Hammer ECN05A1AAA is a NEMA Size 00 enclosed non-combination motor starter designed for reliable full-voltage non-reversing (FVNR) motor control. This NEMA Size 00 enclosed non-reversing starter features a 120V coil in a NEMA 1 enclosure, making it suitable for small motor applications requiring industrial-grade protection. Part of the Freedom Series, the ECN05A1AAA provides compact, drop-in motor control for maintenance and retrofit applications.
Key Features
- Non-combination starter design with 3-pole configuration and 5A current rating
- NEMA Size 00 compact enclosed construction with NEMA 1 enclosure rating
- Compact enclosed starter ideal for small motor control (1-Phase or 3-Phase) with industrial-grade protection
- 120V AC control coil for universal facility voltage compatibility
- Full voltage non-reversing operation—no soft start or ramp functionality
- Overload relay built-in for motor protection
Technical Specifications
Operates at 110/120 V, 50/60 Hz for single-phase applications in NEMA 00 Size 1 enclosure with dimensions 11.5 in L x 7.25 in W x 7.4 in H. The unit features a melting-alloy overload relay for standard motor protection and is rated for small-horsepower motors typical of Size 00 applications.
Typical Applications
- Small machine tool motor control
- HVAC fan and blower starters
- Pump and compressor motor control
- General-purpose industrial machinery with fractional to 1.5 HP motors
- Maintenance and field replacements where compact form factor is required
Compatibility & Replacements
Compatible With
- Single-phase 120V AC supply systems
- Three-phase motors (120V control supply independent of motor voltage)
- Standard industrial 50/60 Hz power distribution
- Facilities with NEMA 1 (general-purpose) enclosure requirements
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The ECN05A1AAA is designed as a direct replacement for other NEMA Size 00 FVNR starters in the same class; however, confirm motor voltage, coil voltage, and auxiliary wiring before substitution.
Works With
- Standard motor control circuits without programmable logic
- Manual push-button start/stop stations
- 24V or 120V auxiliary control devices (selector switches, indicator lamps)
- Conventional three-wire motor control wiring
