Button NEF30-K2X2Y blue W0-NEF30-K 2X2Y N

Purpose and construction of NEF30 control buttons

The NEF30-K control button is an element used to control electrical circuits, designed for mounting in 30.5 mm diameter holes in control panels, machine and device housings. Made of metal, it is characterized by a solid construction and high resistance to mechanical damage. Designed to operate in various environmental conditions, available in climatic versions N/2 and W/3.

Parameters and application

This model, designated as NEF30-K, is a momentary push button with a hidden button. It provides reliable operation in applications requiring frequent switching of circuits on and off. Thanks to the insulation voltage of 500V and the short-circuit withstand current of 1000A, it guarantees safe use and protection of the electrical installation. This button finds application in a wide range of industries – from industrial automation to construction and household appliances.

Key features and benefits

• Durable construction: The metal body ensures long-term operation even in harsh industrial conditions.
• Universal mounting: The standard mounting hole (Ø30.5 mm) allows for easy integration with existing panels and enclosures.
• Safety: Rated insulation voltage of 500V and high resistance to short-circuit currents ensure safe operation of the device.
• Wide range of applications: Ideal for controlling various electrical devices, from simple lighting circuits to advanced automation systems.
• Availability of connecting elements: The ability to configure with EF30 connecting elements (normally open NO, normally closed NC, NO/NC combinations) allows you to adapt the button to specific application needs.
• IP55 protection: Provides protection against water jets and dust, which is important in industrial environments.
• Different climatic versions: Availability of versions N/2 (-15…+30°C) and W/3 (-30…+50°C) allows you to choose the appropriate model for the prevailing temperature conditions.

The rated insulation voltage is 500V, the short-circuit withstand current reaches 1000A and the degree of protection is IP55 – these parameters guarantee reliability and safety of use in demanding applications. The rated thermal current Ith is 10A and the impulse withstand voltage is 2500V.

Remember to choose the appropriate EF30 connecting elements (available separately) to ensure proper operation of the entire control system. Contact configuration (X - NO, Y - NC) allows for flexible adaptation of the button to the specifics of a given circuit.
