| Datasheet | Download Datasheet |
The Littelfuse Startco SB6100-301-0 is a Shock Block special-purpose ground-fault circuit interrupter: a Class D unit rated 100 A (continuous) at 600 V, enclosed version.
It protects people from electric shock on industrial equipment and circuits beyond the reach of standard GFCI receptacles and breakers: it trips on ground-fault current above its trip level and monitors the ground connection to the load.
Trip level: 20 mA (Fixed). Trip time: inverse time trip curve (UL 943); minimum trip time 20 ms. Phases: 3-phase, 3-wire (no neutral), 60 Hz. Short-circuit current rating: 50,000 A. Ground monitoring: load-ground-connection monitor (UL 943C ground monitor/interrupt), required for class C and D; pilot wire + termination device at the load; GC-loop trip resistance 38 ± 2 Ω; open-circuit voltage 12 vdc; nominal loop current 30 mA. Output: auxiliary contact, normally open (N.O.), follows the state of the internal contactor; UL rating 4 A resistive 220/240 vac, 0.3 A resistive 250 vdc.
Enclosure: NEMA 4X, Polyester, Lockable. Operating temperature –35 °C (–31 °F) to + 40 °C (104 °F), up to + 66 °C (151 °F) with derating. Size: H 453.8 mm (17.9”); W 406.2 mm (16.0”); D 223.3 mm (8.8”).
Approvals: UL 943C listed (enclosed); CSA certified (C22.2 No. 144-M91, Class 1451-01); UL 1998 compliant (revision 01 or higher).
