Thermal overload relay for MC75a-100a series contactor MT current 70-95A MT-95 70-95A

Motor Protection with LS MT-95 Thermal Relay (70-95A)

The MT-95 thermal relay from the MT series by LS Electric is a reliable device designed to protect electric motors from overload. This model, with a current adjustment range of 70 to 95A, works perfectly with MC-75a, MC-85a and MC-100a contactors. Its task is to ensure the safe operation of the electrical installation and extend the life of connected devices.

Construction and Application

The MT-95 thermal relay is a protective element that reacts to temperature increases caused by motor overload. If the set threshold is exceeded, the circuit is disconnected, protecting the motor from damage. The device finds wide application in industrial installations, construction, and automation systems. It is particularly useful where there are frequent load changes or a risk of overloads.

Key Features and Benefits

• Wide adjustment range: The ability to precisely adjust the tripping threshold (70-95A) to the specific needs of the application. This allows for optimal motor protection without unnecessary shutdowns.
• Compatibility with LS contactors: Designed to work with popular LS MC series contactors (MC-75a, MC-85a, MC-100a), which simplifies installation and integration into existing installations.
• High reliability: Made of high-quality materials and in accordance with strict safety standards, which guarantees long-lasting and trouble-free operation.
• Overload protection: Provides effective protection of the motor against damage caused by overload – as with most relays of this type.
• Compact dimensions: Allows for easy mounting in limited space within a switchgear cabinet.
• Durable construction: Robust housing provides resistance to environmental conditions prevailing in industrial plants.

The relay is characterized by a current adjustment range of 70 to 95A and belongs to the MT series. It has screw terminals and a rated operating voltage of 690V. The tripping class is 10A or 20, and its dimensions are 70x97x110 mm.

Remember to always check the detailed technical parameters in the manufacturer's documentation. It is worth paying attention to the tripping class – it informs about the relay's reaction time to overload. The choice of the appropriate class depends on the characteristics of the load and the requirements of the application.
