Allen-Bradley 817-E1 is a Bulletin 817 thermistor protection relay designed for monitoring motor winding temperature via PTC thermistor sensors. This DIN rail-mount relay features a DPST (Double-Pole Single-Throw) contact configuration for reliable circuit control. It provides essential overload protection for motors and other equipment by detecting overtemperature conditions and interrupting the control circuit to prevent damage.

Detect overheating in your industrial control systems with this temperature relay from Rockwell Automations 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
