SQUARE D ZB2BE102 Harmony XAC Contact Block, 10 A @ 600 VAC Contact Rating

Square D ZB2BE102 contact block is suitable for use with circuit breakers, relays and switches in electrical circuits for instrumentation and power management operations.

Working Mechanism:

• When the pushbutton is not pressed, the circuit remains open and electricity cannot flow through it.
• When the button is pressed, it closes the circuit by bringing together internal contacts.
• With the contacts connected, electricity can flow through the circuit.
• Releasing the button opens the circuit again, stopping the flow of electricity.

Features:

• Square D ZB2BE102 contact block comes with one normally closed (NC) contact that interrupts the circuit when the pushbutton is activated.
• It has a spring return operator that returns to its original position after activation.
• This Square D Harmony XAC contact block includes front mounting for easy installation.
• It features slow-break contact operation for precise control and gradual interruption to prevent sudden disruptions or damage.
