Why Choose the EMAS MKS1TM-16 Motor Protection Circuit Breaker?
The EMAS MKS1TM-16 is a reliable motor protection circuit breaker designed to protect three-phase electric motors against overloads, short circuits and phase failure. As part of the EMAS MKS series, it combines adjustable thermal protection with fixed magnetic short-circuit protection in a compact device suitable for industrial control panels and machinery.
The adjustable thermal current range of 10 to 16 A allows the protection setting to be matched closely to the motor's rated current. Fixed short-circuit protection at approximately 12 times the operational current provides rapid disconnection during severe electrical faults, helping reduce the risk of motor damage and unplanned downtime.
Designed for mounting on a standard 35 mm DIN rail, the MKS1TM-16 is straightforward to integrate into motor control centres, distribution panels and automation equipment. Its phase-failure protection, ambient temperature compensation and minimum short-circuit breaking capacity of 6 kA at 400 V make it a dependable solution for demanding industrial motor applications.

Reliable Motor Overload and Short-Circuit Protection
Motor protection circuit breakers monitor the current flowing to an electric motor and disconnect the supply when abnormal conditions occur. Adjustable thermal protection responds to sustained overloads, while magnetic protection provides rapid interruption during short-circuit faults.
The EMAS MKS1TM-16 also provides protection against phase failure, an important feature for three-phase motors that could otherwise continue operating with excessive current and overheating. Its compensated thermal mechanism helps maintain dependable trip performance throughout the specified ambient temperature range.
Typical Applications
- Three-phase induction motor protection.
- Industrial pumps, fans and compressors.
- Conveyor and material handling systems.
- Machine tools and production equipment.
- Motor control centres and distribution panels.
- HVAC and building-services machinery.
