Working Mechanism

  • Eaton contact blocks consist of a stationary contact and a movable contact, separated by a small gap.
  • When the movable contact is pressed against the stationary contact, current flows through the circuit.
  • The current stops flowing when the movable contact is released.

Standards and Approvals

  • UL
  • CSA

Frequently Asked Questions

What is the operating temperature range of these contact blocks?

10 to 140 degrees F.

What is the NOEM contact block?

NOEM stands for 'Normally Open, Emergency Close'. These contact blocks are used with electromagnetic devices, such as solenoids or motors. It has a normally open (NO) contact, which opens the circuit as long as the movable contact is not pressed against the stationary contact. During emergencies, the NOEM contact block can be activated to close the circuit and stop the equipment or machinery.

What is the difference between NO and NC contact blocks?

The difference between NO and NC contact blocks is the state of the circuit when the control device is not activated. NO contact blocks are open when the control device is not activated, while NC contact blocks are closed when the control device is not activated.
