Overload Relays

TA Series Image
  • Bimetallic Amb. Compensated
  • Convertible Manual/Auto Reset
  • Setting Ranges Up To 310 Amps
  • Tripping Class 10A
  • UL; CSA Approvals
TA Series thermal overload relays are used in conjunction with ABB A Line contactors for the protection of motors having a nominal voltage of up to 600 VAC max per UL/CSA (690VAC and 800VDC per IEC). These relays are built to be self-protecting in the event of an overload until the short circuit protection device is activated.
  • Trip Indication
  • Optional Remote Trip/Reset
  • Single Phase and Unbalance Protection
  • Variety of Accessories Available
RW Series Image
  • Bimetallic Amb. Compensated
  • Convertible Manual/Auto Reset
  • Setting Ranges Up To 840 Amps
  • Tripping Class 10A
  • UL, IEC, CE Approvals
RW series thermal overload relays can be directly mounted under WEG contactors, assuring electrical and mechanical operation as an open across the line starter. The RW series is a perfect compliment to the CWC and CWM contactors. All sizes provide complete motor protection offering ambient temperature compensation, phase loss sensitivity protection, and current unbalance sensitivity.
  • Variety of Accessories Available
XT Series Image
  • 12~600 VAC/VDC Coils
  • Up to 640 HP @ 230V
  • Up to 1200 HP @ 460V
  • UL; CSA Approved
  • Up to 2000 Amps
The compact, space saving, and easy to install XT line of contactors is the efficient and effective solution for customer applications from 7A to 2000A. Non-reversing contactors are most commonly used to switch motor loads in applications where running over current protection is either not required or is provided separately.
  • 3 or 4 Poles
  • IP20 Finger and Back-of-Hand Proof
  • Large Ambient Temperature Range
  • Plug-In Accessories for Reduced Installation Time
  • Panel or DIN Rail Mounting up to 65A
TF42 Series Image
  • Continuous Temperature Compensation
  • 50/60 Rated D.C. Frequency
  • 690V Rated Insulation
  • Class J Fuse Type
  • Trip Class 10
  • 3 Poles
T16 Series Image
  • Overload protection- trip class 10.
  • Phase loss sensitivity.
  • Adjustable current setting for overload protection.
  • Trip-free mechanism.
Thermal overload relays are economic electromechanical protection devices for the main circuit. They are used mainly to protect motors against overload and phase failures. Starter combinations are setup together with contactors.
  • Direct mounting onto mini contactors or block contactors.
  • Suitable for three- and single- phase application
  • Automatic or manual reset selectable.
BF Series Image
  • Thermal Overload Relays between 0.09 and 420A
  • Independent or Direct Mounting on Contactor
  • Automatic and /or Manual Resetting
  • Non Phase Failure Sensitive Version
  • Thermistor Protection Relay
  • Phase Failure Sensitive
Lovato Motor protection relays thermal overload BF series are three poles three phase and non single phase sensitive.
EF19 Series Image
  • Overload protection trip class 10E, 20E, 30E selectable
  • Adjustable current setting for overload protection
  • Temperature compensation from -25 +70 C
  • Automatic or manual reset selectable
  • Phase loss sensitivity
Electronic overload relays offer reliable protection in case of overload and phase-failure. They are the alternative to thermal overload relays. Motor starters are combinations of overload relays and ontactors.
