Functional Description

CR2940U301 is a Standard Contact Block developed by General Electric. With its heavy-duty design, normally closed contacts, and plunger-style mechanism, it is ideal for use in applications requiring durable switching functionality, including control panels, safety systems, and automation equipment. Its high voltage rating (600 VAC) and flexibility in installation make it a valuable addition to any control or electrical system where reliability is key.

Features

• Standard Block: Classified as a Standard Contact Block, making it versatile and suitable for general switching applications in control circuits. Offers solutions for industrial automation and electrical control systems.
• Contacts: Features a single normally closed (NC) contact. A normally closed contact is designed to allow current flow when the contact block is in its default state. When the contact is activated or triggered, the circuit will be opened, interrupting the flow of current. This feature is essential in circuits where it is necessary to break the circuit under certain conditions, such as during an emergency shutdown or safety operation.
• Plunger Style: Utilizes a plunger style mechanism for its contact operation. In this design, a plunger is pressed or activated to open or close the contacts, providing a reliable and durable means of triggering the contact. The plunger action is often used in systems where a simple, direct push or press is needed to activate the control circuit.
• Maximum Voltage Rating: Rated for a maximum voltage of 600 VAC. This high voltage rating ensures that the contact block can be used in industrial and commercial systems that require reliable operation under higher voltage conditions. It is suitable for use in a wide range of machinery and control systems, including those that handle high-voltage circuits.
• Heavy Duty Design: Designed for heavy-duty applications, meaning it is built to withstand the stresses of high-current circuits and rigorous industrial environments. This durability makes it a suitable choice for machines and systems where reliability and longevity are crucial.

Mounting and Installation

• It can be integrated into custom panels or systems that already have an existing mounting configuration, allowing users to place it where it is most convenient for their application.
• The compact size and plunger mechanism allow it to be mounted and operated in a variety of configurations, making it a versatile choice for control and automation systems.

Frequently Asked Questions

What is CR2940U301?
It is a Standard Contact Block developed by General Electric.

What does normally closed (NC) mean in this contact block?
Normally closed (NC) refers to the default state of the contact. In its natural state, the circuit is closed, allowing current to flow through. When the contact block is activated (via a plunger), the circuit is opened, interrupting the flow of current. This is typically used in emergency or safety applications where breaking the circuit is necessary under specific conditions.

What is the voltage rating?
It is rated for a maximum of 600 VAC (Volts alternating current). This allows it to handle high-voltage electrical circuits commonly found in industrial control systems.

How is the contact block mounted?
The contact block is designed to be panel-mounted but does not include a mounting plate. This provides flexibility for installation, allowing it to be easily integrated into existing control panels or customized mounting configurations.

Can the block handle high-current applications?
Yes, the block is designed for heavy-duty applications. It can handle currents typical in industrial control circuits, making it suitable for environments where high electrical loads are common.

How does the block differ from other contact blocks?
The block stands out due to its normally closed (NC) configuration, plunger-style activation, and ability to handle up to 600 VAC. Unlike some other contact blocks, it does not come with a mounting plate, providing installation flexibility.
