Why Choose the IMO MT5-61-70 Thermal Overload Relay?
The IMO MT5-61-70 is a dependable thermal overload relay designed to protect three-phase electric motors against sustained overload conditions and phase-related faults. Developed for industrial motor-control applications, it helps prevent excessive motor heating, insulation damage and premature equipment failure.
With an adjustable current range of 61–70 A, the MT5-61-70 allows the protection setting to be matched closely to the motor’s rated full-load current. This adjustable configuration supports accurate overload protection across a range of industrial motors, machinery and electrical control systems.
The relay is designed for use alongside a compatible IMO contactor within a motor starter assembly. Its compact construction, straightforward adjustment and manual or automatic reset functionality make it suitable for installation in control panels, motor-control centres and machinery cabinets.
Key Advantages
- Reliable thermal overload protection for three-phase motors.

- Manual or automatic reset selection.
- Integrated trip indication for easier fault diagnosis.
- Auxiliary trip contacts for control and signalling circuits.
- Designed for industrial motor starter assemblies.
Reliable Protection for Industrial Motors
Thermal overload relays monitor the current drawn by an electric motor and disconnect the control circuit when an overload persists beyond a safe period. This helps protect motor windings from damaging temperature rises while allowing temporary starting currents to pass without unnecessary tripping.
The adjustable setting of the IMO MT5-61-70 enables commissioning engineers to coordinate the relay with the motor nameplate current. When combined with a correctly selected contactor and short-circuit protection device, it forms an effective motor starter and protection system.
Typical Applications
- Industrial pumps, fans and compressors.
- Conveyors and material-handling equipment.
- Production and packaging machinery.
- Mixers and processing equipment.
- Heating, ventilation and air-conditioning systems.
- Motor-control centres and electrical control panels.

Frequently Asked Questions
What is the IMO MT5-61-70 used for?
The relay is used to protect three-phase electric motors against sustained overload conditions and phase-related faults in industrial motor-control systems.
What is the current range of the MT5-61-70?
The overload setting can be adjusted between 61 and 70 A to suit the rated current of the connected motor.
Does this overload relay replace a circuit breaker?
No. A thermal overload relay protects the motor against sustained overloads, while a correctly rated fuse or circuit breaker is still required for short-circuit protection.
Can the relay be reset automatically?
The MT5-61-70 provides selectable manual or automatic reset operation, allowing it to be configured for the requirements of the motor-control system.
Where is the IMO MT5-61-70 normally installed?
It is typically installed with a compatible contactor inside an electrical control panel, motor-control centre or industrial machinery cabinet.
