Overview
The Allen-Bradley W26 is a Type W thermal overload heater element engineered for use with Allen-Bradley overload relays and motor starters. These heater elements are eutectic alloy type overload relays for Bulletin 500 line starters with Class 20 protection. The W26 provides consistent and reliable thermal protection across a range of full-load amperage ratings, making it a standard choice for industrial equipment manufacturers and maintenance professionals.
Key Features
- Eutectic Alloy Construction: Type W heater elements for the 500 Line provide Class 20 operation recommended for general applications
- Compatible Series: Designed specifically for Bulletin 500 starter line thermal overload relays
- Proven Reliability: Standard Allen-Bradley overload protection element used across motor control equipment
- Multiple Current Ratings: Available for different motor sizes and full-load amperage requirements
Technical Specifications
The W26 heater element is rated for maximum continuous current operation. The element provides 0.90 AMP rating for Size 00-0 and 0.88 AMP rating for Size 1 configurations. The W26 is rated for 0.8 maximum amps and is suitable for use with thermal overload relays, magnetic motor starters and motor controls. The eutectic alloy design ensures fast and accurate trip characteristics at Class 20 thermal protection levels.
