Remarks | Item description:
- Space-saving ECB with two channels
- Nominal current is fixed at 3.8 A for each channel
- Each output complies with NEC Class 2
- Active current limitation
- Switch-on capacity > 65000 F per channel
- One illuminated, three-colored 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
Nominal current: 2 x 3.8 ADC NEC Class 2 (at 20 24 VDC); 2 x 3.2 ADC NEC Class 2 (at 28 VDC) fixed nominal current
Switch-on behavior: Time-delayed channel switching (load-dependent, min. 50 ms / max. 5 s)
Remote input: Reactivation of all tripped channels via 15 30 VDC pulse for min. 500 ms Switching on/off any number of channels via pulse sequence.
