Actually, the ZBE*** contact blocks are slow break action that means they are dependent of the head fitted with.

For example, if the customer is using a standard pushbutton, as a ZB4BA*, the speed of actuation of the contact block is directly linked to the speed actuation of the head.

At the opposite, if the customer is using an e-stop, which is a trigger action product like a snap action actuator, the contact block will be actually like that, i.e. closed to a simultaneous actuating.
