Product Description

  • XB2 series buttons are used in industrial control circuits with AC 50HZ or 60HZ, rated working voltage to 660V and DC working voltage to 440V. They are used as magnetic starters, contactors, relays and other electrical circuits. The buttons with indicator lights are also suitable for lighting signal indication places.
  • The button is composed of three parts: contact module, base frame and button. The three parts are connected by self-locking connection without fasteners, which is internationally accepted. It is safe, reliable, easy to disassemble and assemble, and has a long service life.
  • Button contact module adopts modular structure, high contact reliability, simple maintenance (only one screwdriver can replace all the components on the back of the panel). The contact is made of silver-copper composite material, and the current is up to 10A.

 

Product overview

  • Installation holes of all buttons in this series are 22mm.
  • Metal button adopts anti-channeling operation head. Button can not be removed from the front.
  • All metal contacts have the most important role of switching circuit and self-cleaning, and can still ensure the reliability of contact in low voltage and low current {5v, 5mv} use.
  • Often open and normally closed contacts are independent of each other. When used, they can be combined according to the need for easy replacement.
  • It is widely used in industrial control circuits with AC 50Hz, rated working voltage of 0-380v and DC working voltage of 0-220v.
  • It is used for the control of magnetic starter, contactor, relay and other electrical circuits.
  • Standard operating environment: ambient temperature: – 25 ~+55 (no freezing) operating humidity: 45 ~85% RH (no condensation)
  • Contact resistance: <50m
  • Insulation Resistance: > 100m
  • Maximum voltage withstand: 3000 volts, 50 Hz AC
  • Vibration resistance: 50 Hz, amplitude about 1 mm
  • Shock resistance: greater than 10m/s2 (about 10G)
  • Life: Machinery (1 million) Electric (more than 30,000 times)
