Mun Hean Technology Pte Ltd was founded five years after MH Protection Relays was released in 1981, designed by Mun Hean Singapore Pte Ltd, manufactured in Japan, and has long been the market leader in industrial electrical protection.
The sole purpose of Mun Hean Technology is to continue to research, design, and create to satisfy customers’ needs for a safe, efficient, and reliable system. At that moment, a Mechanical Trip Button (MTB) System was originated, patented, and replaced how we traditionally manage and protect our electrical system. Click here to learn how an MTB operates.
With technology advancements, Mun Hean Technology continues its research & development, showcasing & training, listening & consulting.
In mid-2020, a new generation of Earth Leakage Relay and Earth Fault Relay (DTL type) had developed into complete Digital Electronics. It comes with memory, self-health check, fault trip differentiation by authentic/other means, early warning signal before a fault, built-in communication protocol, and remains compact sizes.

In late 2020, to ensure MH Relays is up to the latest International Standard (IEC) and provide the user the trust and reliability, we worked with TÜV SÜD PSB Singapore, a trusted partner of choice in safety, security, and sustainability solutions. MH Protection Relays complied with the IEC test standards and the requirements for product safety, electromagnetic compatibility, environmental, CE marking, and many more.
In the 3rd quarter of 2022, the 5th generation MH Relays will be launched and have all Digitalized Protection Relays updated with new Smart features. Stay tuned to our news!
