CE, cULus Listed

Detect overheating in your industrial control systems with this temperature relay from Rockwell Automation’s Allen Bradley range. An internal alarm and LED (light-emitting diode) indicators warn you if your system becomes too hot, alerting you to open and short circuits. The unit's DPST (double pole, single throw) contact configuration lets you switch live and neutral circuit connectors off and on simultaneously. This gives you full control over the relay system for safety and ease of operation.

• 24 to 240V AC/DC supply voltage range for high-energy industrial systems
• Wide operating temperature range of -25°C to +60°C for use in harsh environments
• Fitted with LED (light-emitting diode) bulbs that are energy-efficient and long-lasting
• Compact 22.5mm DIN rail mount housing for simple installation in small spaces

• BS EN (British Standards European Norm Electrostatic Control Standards)
• ANSI/ESD (American National Standards Institute/Electrostatic Discharge Standards)
• UL (Underwriters' Laboratories)
• CE (Conformitè Europëenne)

You can use this relay in motor-control circuits, including transformers, bearings and compressor systems, to monitor potentially dangerous temperature changes.
