Current Sensitive Relay

Current Sensitive Relay

The Model 2734 Current Sensitive Relay offers precise current monitoring essential for industrial control systems. Its configurable operating voltage, supporting both 24VAC and 120VAC, provides installation flexibility across various power infrastructures. Users can adjust the over-current range from 0.5 to 20 amps by varying current transformer passes, accommodating diverse load requirements with accuracy. The device features a user-selectable reset function, allowing for either automatic or manual operation, which enhances system control and fault recovery procedures. With a robust 10A at 240VAC resistive contact rating and a trip delay adjustable from 0.2 to 2.5 seconds, the 2734 ensures reliable circuit protection and operational stability. Its durable ABS plastic enclosure contributes to its longevity in demanding operational environments, maintaining performance across an operating temperature range of +32° to +140° F. This relay is engineered for consistent, dependable service.
