The Next Generation Smart Circuit Breaker for Thailand's Smart Buildings & Industries

Thailand is accelerating its transition toward smart buildings, intelligent factories, and energy-efficient infrastructure. As electricity costs continue to rise and safety regulations become more stringent, traditional miniature circuit breakers (MCBs) are no longer sufficient to meet modern facility management requirements.

Acrel ASCB2 Smart MCB is designed to transform conventional electrical distribution into an intelligent, connected, and proactive protection system—without replacing the entire distribution panel.

Why Thailand Needs Smart MCBs

Many commercial buildings, hotels, hospitals, schools, factories, and office buildings in Thailand still rely on conventional MCBs that only provide basic overload and short-circuit protection.

This means:

Electrical faults are difficult to locate.
Hidden overheating can develop unnoticed.
Maintenance remains reactive instead of preventive.
Energy consumption cannot be monitored at the circuit level.
Facility managers cannot remotely control or monitor branch circuits.

ASCB2 changes this completely.

One Device, Complete Protection

Unlike traditional breakers, ASCB2 integrates metering, protection, communication, and remote control into one compact device.

It continuously monitors:

Voltage
Current
Power
Energy
Frequency
Terminal temperature
Leakage current (Type A)
Overload
Short circuit
Over/Under voltage
Phase loss (3-phase)

When abnormalities occur, the system immediately sends alarms to the cloud platform, mobile APP, or maintenance personnel, enabling faster response before faults become costly outages or fire hazards.

Built for Smart Retrofit Projects

One of the biggest challenges in Thailand is upgrading existing distribution boards without expensive reconstruction.

ASCB2 is specifically designed for this market.

It offers:

Direct replacement of conventional MCBs
Support for 1P, 2P, 3P and 4P circuits
Wireless communication for easier installation
No additional control wiring
Minimal panel modification
Remote parameter configuration

This makes it an ideal solution for building renovation projects, where installation space is limited.

More Than Protection

ASCB2 helps facility managers move from passive maintenance to predictive maintenance.

ASCB2 is suitable for:

Commercial buildings
Hotels & Resorts
Hospitals
Schools & Universities
Shopping malls
Manufacturing plants
Industrial parks
Office buildings
Data centers
Elderly care facilities
Smart street lighting
