Why Choose the EMAS MKS1-YKD01 Auxiliary Contact Block?
The EMAS MKS1-YKD01 is a compact and reliable auxiliary contact block with 1 normally open (1NO) and 1 normally closed (1NC) contact, designed for use with EMAS MKS Series motor protection circuit breakers. As part of the EMAS MKS1 motor protection accessory range, this device provides additional electrical signalling and control contacts for industrial motor starters, automation systems and electrical control panels.
The MKS1-YKD01 enables the switching position of a compatible motor protection circuit breaker to be incorporated into external control and monitoring circuits. Its 1NO + 1NC contact arrangement provides complementary switching functions, making it suitable for PLC status inputs, auxiliary control circuits, motor starter indication and electrical interlocking applications.
Designed for direct mechanical integration with compatible EMAS MKS motor protection switches, the auxiliary contact block offers straightforward installation without requiring a separate operating coil. Its compact construction, screw-terminal connections and 3 A AC-15 operating current rating at 230 V AC make it a practical accessory for industrial motor control and electrical automation equipment.

Reliable Auxiliary Signalling for Motor Protection Systems
Motor protection circuit breakers are used to protect electric motors and associated circuits against overload and short-circuit conditions. The EMAS MKS1-YKD01 auxiliary contact block extends the control and signalling capabilities of compatible MKS motor protection switches by providing additional mechanically operated contacts.
The 1NO + 1NC configuration allows complementary electrical signals to be generated as the associated motor protection switch changes operating position. These contacts can be connected to PLC inputs, control relays, indicator lamps or other suitably rated control equipment to provide status information and support automated control sequences.
The MKS1-YKD01 is particularly useful in industrial motor starter assemblies where additional contact functions are required without installing a separate position-sensing device. Its compact, side-mounted arrangement supports efficient electrical panel layouts and simplifies integration with compatible EMAS motor protection equipment.
Typical Applications
- EMAS MKS motor protection circuit breaker assemblies.
- Industrial motor starter control panels.
- Motor protection switch position indication.
- PLC input monitoring and automation interfaces.
- Electrical interlocking and auxiliary control circuits.
- Motor control centres and industrial distribution panels.
- Machinery automation and manufacturing equipment.
- Control relay and contactor signalling circuits.
