The Wago 787-1664/000-080 is a space-saving, 4-channel electronic circuit breaker (ECB) suitable for 24 VDC input voltage systems. Each channel's nominal current is adjustable from 1 to 10 A, either via a sealable selector switch or through the integrated IO-Link interface. This feature allows for precise current control tailored to specific application needs.
The ECB supports a switch-on capacity of over 50,000 µF per channel and features time-delayed channel switching, with a delay ranging from 16 ms to 100 s, dependent on the load. Each channel is equipped with an illuminated, three-colored button for simplified switching (on/off), resetting, and on-site diagnostics. The IO-Link interface also enables status messaging and current measurement for each individual channel, as well as remote control for switching channels on or off.
Designed for DIN rail mounting, this circuit breaker operates within an input voltage range of 18 to 30 VDC. It has a low voltage drop of ≤ 200 mV and an internal fuse rated at T 15 A for circuit protection. The efficiency is typically 99%, with power losses of ≤ 0.84 W at no load and ≤ 10 W at 4 x 10 A load.
The nominal input voltage is 24 VDC, with an operating range of 18 to 30 VDC.
The nominal output current is adjustable from 1 to 10 A per channel via a sealable selector switch or the IO-Link interface.
The switch-on capacity is greater than 50,000 µF per channel.
The trip time ranges from 16 ms to 100 s, depending on the load.
Yes, it features an IO-Link interface for status messaging, current measurement, and remote channel control.
It is designed for DIN rail mounting.
