Singapore, 01/07/2026, Mun Hean announces that one of its flagship products, the MH Protection Relay was granted its first patent, in the design of its proprietary MTB (Mechanical Trip Button).

The MH electrical protection relay has developed over several generations into an advanced solution engineered to enhance the stability, precision and reliability of modern electrical protection systems.

Developed in response to increasingly complex operating environments, the patented design addresses key limitations in conventional protection relays, where sensitivity to transient conditions can result in unnecessary tripping and system disruption. Mun Hean’s approach introduces a more controlled and refined trip mechanism, supporting consistent system performance under dynamic load and network conditions.

“Electrical protection today requires more than responsiveness — it requires precision,” said Er. Voon Yip Seng, Senior Manager of Mun Hean Singapore. “The MH Protection Relay with MTB reflects our focus on engineering solutions that respond intelligently to real-world operating conditions, enabling greater system stability and operational confidence.”

By rethinking traditional trip response design, the integration of a mechanical trip button enables improved control over protection behaviour while maintaining the integrity of system safety. This results in enhanced operational continuity, particularly in environments where reliability is critical and interruptions carry significant consequences.

The solution is well-suited for applications across industrial operations, energy systems and critical infrastructure. Its relevance is especially pronounced in high-performance environments such as Battery Energy Storage Systems (BESS), where precise protection and system stability are essential.

This milestone reinforces Mun Hean’s commitment to advancing engineering excellence through purposeful innovation. The company continues to invest in the development of solutions that address evolving demands in power quality, system performance and protection design.

Further technical insights and application perspectives will be shared through upcoming industry engagements and digital platforms.
