SCHNEIDER ZA2EE101 Central control module

Schneider Electric ZA2EE101 Overview

The Schneider Electric ZA2EE101 is an emergency stop mushroom head push button contact block. It is typically used in conjunction with Schneider Electric's Harmony series control and signaling units to build emergency stop push buttons.

Product Detailed Description

• Function:

• The ZA2EE101 is a contact block that, when combined with a suitable mushroom head push button operator (e.g., ZB4BS or ZB5AS series), forms an emergency stop push button.

• It provides normally closed (NC) safety contacts used to cut off control circuits in emergency situations, thereby stopping machinery or processes to ensure safety.

• Its design complies with safety standards and typically features a positive opening operation.

• Features:

• Single normally closed (NC) contact.

• Screw-clamp terminals for easy and reliable connection.

• Compatible with Schneider Electric's Harmony series modular control and signaling units.

• Easy to install onto the control unit body.

• Typically slow-break contacts.

Product Parameters

As the ZA2EE101 is just a contact block, its parameters are generally related to the control unit and operator it is used with. Here are some typical parameters for contact blocks:

• Contact Type:

• Normally Closed (NC)

• Number of Contacts:

• 1

• Terminal Type:

• Screw-clamp terminals

• Rated Insulation Voltage (Ui):

• Typically 600 V (conforming to IEC 60947-1)

• Rated Impulse Withstand Voltage (Uimp):

• Typically 6 kV (conforming to IEC 60947-1)

• Rated Operational Current (Ie):

• 3 A at 240 V AC-15

• 1.5 A at 480 V AC-15

• 0.1 A at 250 V DC-13

• Varies depending on voltage and load type, for example:

• Degree of Protection (IP):

• Achieves IP65 or higher when assembled with suitable control units and operators.

• Operating Temperature:

• Typically -40 °C to +70 °C

• Standards Compliance:

• IEC 60947-5-1

• EN/ISO 13850 (when combined with suitable operators)

Product Advantages

• Reliable Emergency Stop Functionality:

• Provides reliable normally closed contacts for emergency interruption of control circuits.

• Compatibility with Harmony Series:

• Easy integration with Schneider Electric's Harmony series control and signaling units.

• Easy Installation and Connection:

• Screw-clamp terminals facilitate wiring.

• Modular design allows for easy installation onto the control unit body.

• Compliance with Safety Standards:

• Complies with the safety requirements for emergency stop push buttons when combined with suitable operators.

• Robust and Durable:

• Designed for industrial environments.

Precautions

• Use with Suitable Operators:

• The ZA2EE101 must be used with a mushroom head push button operator that meets emergency stop requirements (e.g., ZB4BS or ZB5AS series) to form a complete emergency stop push button.

• Correct Installation and Wiring:

• Follow Schneider Electric's installation guidelines to ensure the contact block is correctly mounted onto the control unit and wired properly.

• Safety Circuit Design:

• Integrate the emergency stop push button into a safety circuit that complies with relevant safety standards.

• Regular Testing:

• Periodically test the functionality of the emergency stop push button to ensure it can reliably cut off power in an emergency.

• Follow Safety Standards:

• Always adhere to relevant safety standards and regulations when designing and using emergency stop circuits.
