Description

The Thermistor Motor Protection Relay is designed to monitor PTC temperature sensors using one sensor circuit. It features dynamic interrupted wire detection and non-volatile fault storage. The relay operates based on the closed-circuit principle and has three LEDs for visual indication. With a rated control supply voltage of 24 to 240 VAC/DC, this relay is versatile in its power requirements. It also includes 1 normally open (NO) and 1 normally closed (NC) output contact, both rated at 250 V/4 A. The relay continuously monitors for interrupted wires and will automatically reset once the failure has been resolved. For easy installation, the relay is equipped with double-chamber cage connection terminals.
