ABB Thermal Overload Relay, 690V AC Voltage Rating, 2W Maximum Power Loss Per Pole - TF42 Series - TF42-4.2
Shield your sensitive control components from power faults with this thermal overload relay from ABB. The device trips when its circuit's current rises too high, which stops damaging faults from getting to downstream equipment. As its full-load current ranges between 3.1 and 4.2A, the unit adjusts to the power supply, making it a versatile option. Installation is simple as it mounts directly to a contactor without extra wiring. Thanks to the relay's trip-free mechanism, it breaks its circuit even if its actuator sticks to prevent disruption caused by tampering.
Features & Benefits
• Automatic and manual reset functions to suit your application's needs
• Two auxiliary contacts for automatic control-device signalling
• Front-mounted screw dial for easy adjustment of the current setting
• Low maximum power loss of just 2W to cut down on energy use
• Built-in stop function to quickly shut equipment down for hassle-free inspection
