• Space-saving electronic circuit breaker with 2 channels
• 2–10 A nominal current, adjustable for each channel via sealable selector switch
• Switch-on capacity > 50,000 μF per channel
• One illuminated bi-color button per channel simplifies switching (on/off),
resetting, and on-site diagnostics
• Time-delayed switching of channels
• Tripped message (group signal)
• Status message for each channel via pulse sequence
• Remote input resets tripped channels or switches on/off any number of channels
via pulse sequence
