857-640 Description

Wago 857-640 is a fixed-type timing relay module featuring push-in CAGE CLAMP spring connections for secure and efficient wiring. It is designed to handle a rated current of 6A continuously, with specific ratings for different conditions: 3A at 250Vac (AC-15), 2A at 24Vdc (DC-13), and a maximum inrush current of 20A for 20ms at AC. This module incorporates multi-function timer contacts, a yellow LED indicator, and is suitable for railway applications with its electromechanical design. It recommends a minimum switching load of 10V / 10mA / 24V / 1mA and offers a 1C/O / SPDT (Single Pole Double Throw) contact resistance. The ambient air temperature for storage ranges from -25°C to +70°C. It provides a degree of protection IP20 and has a net width ranging from 16.8-31.2Vdc (24Vdc nominal), with a control voltage range of 0.7...1.3 x Uc. The module supports a 250Vac maximum switching voltage, has a control voltage (AC) of 4 kV, and is designed for use with a single-pole / 1-pole (1P) rated active power. It features Silver-Tin (AgSnO) contacts and is capable of 50,000 operations at a rated operating voltage (Ue), with a trip current rating of 5,000,000 operations. The control circuit's rated current offers an adjustable time range for precise timing control, and it is designed to mount on a DIN-35 rail. The dimensions are H94mm x W6mm x D97.8mm, with a 6mm width, ensuring a compact fit for industrial applications.
