Energy-saving Electronic Overload Relays
Industry type:Productivity and energy
Product model number:EOL-40/80/200
award 3

TECO EOL serial-energy-saving Electronic Overload Relays provide more energy saving with tradition Relays about 20 times. Complying with CNS/IEC/UL/CSA/GB standards and certificated by UL/CSA/TUV and 3C, it’s easy sale to global market. We got the patient with Taiwan & China & USA.

Built in 3-Currenr transformer(CT) and use Microprocessor Control Unit(MCU) for current detect & quickly protection when failure happen, it’s easy operation。

The feature for EOL serial-energy-saving Electronic Overload Relays:

‧Microprocessor Control Unit(MCU) for accurate current detect & Ag contact for high control rated capacity。

‧Self-Power design, no more addition Power。

‧Multi-Protection have overload & phase lose & phase unbalance & inrush current protection。

‧Adjustable trip class curve there are class 5/10/20/30。

‧Wide adjustable current range from 100% to 500%。

‧Immediately response time for phase lose(3 seconds) & phase unbalance(3 seconds) & inrush current (0.3 seconds)。

‧Power indicate & trip indicate & test function。

‧Energy saving between tradition relays about 20 times (Tradition 6W,Electronic 0.3W)。

‧4 function in1 operating knob for automatic reset/automatic reset with stop/manual reset/ manual reset with stop。

Founded in 1956 for motor manufacturing, TECO Electric & Machinery forms a green-energy ecological system, capable of providing solutions for energy generation, energy storage, and energy conservation.
For its core electromechanical products, TECO has continued to develop low-carbon industrial solution air system solutions, automated and intelligent products, and optimal energy-conservation, emission-reduction solutions. Concerning green energy, it has been engaged in offshore wind power onshore substations, PV power stations, and energy storage systems, contributing to energy transformation for smart cities. In addition, it has stepped into the production of e-vehicle powertrain, helping with development of smart energy-conserving urban life.
TECO aims to attain "carbon neutrality" and strives to materialize its corporate mission of "energy conservation, emission reduction, intelligence, and automation," in order to create a sustainable future.


Based on its core technologies in electromechanical integration, energy-related engineering, and air solutions, TECO’s three major business groups will serve as the key cornerstones of the internal ecosystem, while the inter-business products and technologies are applied in six major areas areas: smart manufacturing, EV powertrain system, smart energy grid/storage system, offshore wind power business, smart logistics, and smart city applications. In addition, with the ultimate goal of "carbon neutrality", TECO will continue to realize the corporate sustainability and the company vision of “energy conservation, emissions reduction, Intelligence and automation”.
