Why Choose the EMAS MKS1TMK-20 Motor Protection Circuit Breaker with Enclosure?
The EMAS MKS1TMK-20 is an enclosed thermal-magnetic motor protection circuit breaker designed to protect three-phase electric motors against overloads, short circuits and phase failure. Part of the dependable EMAS MKS series, it combines adjustable motor protection with a durable enclosure, providing a practical solution for machinery, pumps, conveyors and industrial control systems.
Its adjustable thermal current range of 16 to 20 A enables the protection setting to be matched closely to the motor's rated operating current. Fixed magnetic short-circuit protection at approximately 12 times the operational current provides rapid disconnection during high-current faults, helping reduce equipment damage and unplanned downtime.
The MKS1TMK-20 is supplied in an IP65 enclosure, providing protection against dust and water jets. With a minimum short-circuit breaking capacity of 6 kA at 400 V, phase-failure protection and ambient temperature compensation, it is suitable for demanding industrial locations where reliable enclosed motor control is required.

Reliable Enclosed Protection for Industrial Motors
Motor protection circuit breakers monitor the current supplied to a motor and disconnect the circuit when unsafe conditions occur. The adjustable thermal release responds to sustained overloads, while the magnetic release provides rapid interruption during severe short-circuit faults.
The EMAS MKS1TMK-20 also protects against phase failure, helping prevent overheating and winding damage in three-phase motors. Its IP65 enclosure provides additional protection in dusty or damp environments, making the unit suitable for installation close to industrial machinery and process equipment.
