CE, cULus Listed

This Allen Bradley temperature monitoring relay from Rockwell Automation is an electrically controlled switch that turns the power on or off in a circuit. Its two contacts operate simultaneously to prevent overtemperature, opening or closing when the temperature is within or beyond the preset threshold. The first contact supplies power to a circuit or device, while the second activates an alarm to alert you if the temperature exceeds the desired limit.

• Compact dimensions of 98.8 (L) x 22.5 (W) x 89mm (H) for use in tight spaces
• Broad operating temperature range of -25°C to +60°C for use in a variety of hot and cold environments
• Wide supply voltage range of 24 to 240V AC/DC makes it suitable for most power applications
• Trimmer potentiometers provide a simple way to set overtemperature thresholds

• CE (Conformité Européenne)
• UL (Underwriters' Laboratories)

Monitoring relays are a type of relay that trip a circuit breaker when a fault is detected. They measure a given parameter, such as voltage or temperature, and will trip when the parameters get too high or low. A normal relay doesn't offer this protective monitoring function.
