Reverse Phase Relay
The Model 253 Reverse Phase Relay provides essential protection for industrial systems. Engineered for reliability, it senses phase reversal with a rapid 0.05-second response time, ensuring prompt system safeguarding. Its wide operating range of 190-480 VAC accommodates diverse electrical environments, operating effectively from -20° to +131° F. With a robust design, including an ABS plastic case and 2500V transient protection, this relay offers consistent performance. The automatic reset function minimizes downtime, while UL Recognized and CSA Certified approvals confirm its adherence to industry standards. Output contacts are SPDT 10A at 240VAC resistive, with an electrical relay life of 100,000 operations at rated load. A 5-year warranty underscores its durability and long-term operational value. This component is a practical solution for critical phase monitoring applications requiring precise and dependable operation.
