Product Code |
Base Model UK5 - Fixed screw-terminal model reference |
Fuse Carrier HESI - Hinged carrier for G-type 5×20mm, 5×25mm or 5×30mm fuses |
Indicator LED - LED indicator; 24 reference only |
Indicator Voltage 24 - LED version; nominal 24V, operating range 15-30V AC/DC |
UK5-HESI terminals provide one fuse position, one row, two screw connections and one potential when the fuse circuit is closed. The hinged carrier accepts G-type 5×20mm, 5×25mm or 5×30mm fuses. Select the plain carrier or an indicator version for the operating voltage.
| Model | Indicator option | Indicator voltage | Indicator current | Nominal cross section |
|---|---|---|---|---|
| ULO-TB350-UK5-HESI | Plain | Not applicable | Not applicable | 1mm² |
| ULO-TB350-UK5-HESILED/24 | LED; nominal 24V | 15–30V AC/DC | 3.5–8.1mA | Not specified |
| ULO-TB350-UK5-HESILA/250 | Indicator | 110–250V AC/DC | 0.5–1mA | 1mm² |
The indicator operating range is separate from the terminal insulation rating. Apply the selected indicator's voltage range to the indicator circuit.
| Rating condition | Current | Voltage | Impulse voltage |
|---|---|---|---|
| IEC nominal; overvoltage category III, pollution degree 3 | 6.3A | 800V | 8kV |
| IEC; category III / degree 2 and category II / degree 2 | Not separately specified | Not specified | Not specified |
| UL use group B | 12A | 600V | |
| UL use group C | |||
| UL use group D | Not specified | Not specified |
The maximum load current for the plain and LA/250 versions is 6.3A. The LED/24 version has a 6.3A nominal current; no separate maximum load value is specified. The use-group ratings do not increase the installed fuse rating.
