Overview
The Dayton 6ECC1 is an IEC-style thermal overload relay designed for three-phase motor protection. With a current range of 4.0–6.0A and Class 10 trip rating, this relay detects motor overload conditions and signals the contactor to break power before damage occurs. It features adjustable current settings, making it suitable for drop-in replacement in existing automation systems.
Key Features
- Bimetallic sensing element — Contains bimetallic strips that bend when current exceeds threshold, breaking the circuit
- Dual reset modes — Manual and automatic reset buttons for flexible operation
- Temperature compensation — Built-in temperature compensation for consistent protection across ambient conditions
- IEC-compatible design — Works with Dayton IEC contactors rated 9 to 18 Amps
- Safety features — Includes tripped indicator, test button, stop button, and finger-safe terminals
- Certifications — UL and CSA listed
