The Wago 787-1664 is a space-saving, 4-channel electronic circuit breaker designed for 24 VDC systems. It offers an adjustable current rating for each channel, ranging from 2A to 10A, controlled via a sealable selector switch. The device features a high switch-on capacity of over 50,000 μF per channel and supports time-delayed switching.
On-site diagnostics and operation are simplified with an illuminated, three-colored button per channel for switching, resetting, and status indication. It also provides a tripped message as a group signal and individual status messages via pulse sequence. A remote input allows for resetting tripped channels or controlling channel on/off states.
This circuit breaker is suitable for DIN rail mounting and operates within an input voltage range of 18-30 VDC. It boasts high efficiency (99%) and a low power loss of ≤ 0.84 W under no load conditions. The MTBF is rated at over 500,000 hours, indicating high reliability for industrial applications.
