Transparent overload relay with screw terminals, 5.5-8A, 1NO/1NC contacts

Schneider Electric

Schneider Electric LR2K0314 Overload Relay 5.5-8A 1NO/1NC

SKU CH-QC0E-Z3KXB

Thermal overload relay protects motors at 5.5–8 A with 1NO/1NC contacts, auto-manual reset and screw-clamp terminals

  • TypeIndustrial Electrical Controls & Automation
  • ColorTransparent
  • Protects motors from overload with 5.5-8 A adjustable range
  • Trip Class 10A ensures fast response to overcurrent events
  • Auto and manual reset options simplify recovery after a trip
  • Direct contactor mounting and screw clamp terminals speed installation
  • 690 V AC / 250 V DC signalling ratings suit industrial control circuits

Application Fit

The Schneider Electric LR2K0314 is a thermal overload relay designed for three-phase motor protection in industrial control panels. It suits electricians and maintenance engineers who need adjustable overload settings between 5.5 A and 8 A with a Trip Class 10A response. Buyers requiring protection outside this current range or a different trip class cannot use this unit.

Contact Configuration

The integrated auxiliary block provides one normally open and one normally closed contact for signalling or interlocking circuits. These contacts are rated for 690 V AC and 250 V DC, allowing direct connection to PLC inputs, indicator lights or contactor coils without additional relays. The screw-clamp terminals accept solid or stranded conductors for secure wiring.

Mounting & Compatibility

Direct mounting onto TeSys Deca and TeSys K contactors reduces panel space and eliminates separate DIN-rail hardware. The transparent housing lets technicians verify contact status visually during commissioning or fault finding. Auto and manual reset modes are selectable on the front, so the relay can match the recovery procedure required by each machine.

Questions about this item

How often will the thermal overload element need replacement under normal operation?

The thermal overload element is built for continuous duty and does not have a scheduled replacement interval; it trips at the set current and can be reset manually or automatically.

What stops the relay from running continuously at the 8 A maximum setting?

The Trip Class 10A characteristic limits sustained operation; if current stays at 8 A the relay will trip within the class-defined time to protect the motor.

How much heat does the relay produce when mounted directly on a contactor all day?

Heat output is determined by the 5.5 A to 8 A setting range and the screw-clamp terminals; the unit is designed for direct contactor mounting without additional cooling.
