Overview

The Littelfuse SB5032-301-0 Industrial Shock Block® is a UL Listed ground-fault circuit interrupter (GFCI) designed for personnel protection in industrial environments. This fixed 20 mA trip device operates at 600 V and provides inverse-time trip protection per UL 943C Class D standards, ensuring rapid disconnection of power during ground-fault conditions to minimize electric shock hazards. The SB5032-301-0 is part of Littelfuse’s SB6000 series, featuring a 100 A continuous current rating and 50,000 A short-circuit current rating for robust performance in 3-phase, 3-wire (no neutral) 60 Hz systems. Its NEMA 4X polyester enclosure with lockable design meets demanding environmental conditions from -35°C to +40°C (derated to +66°C), making it suitable for harsh industrial settings. The device is UL Listed for enclosed models and UL Recognized Component for open-chassis models, with CSA certification for additional compliance. Installation is simplified with 2/0 AWG wiring requirements and compatibility with standard mounting options like the AC6000-MNT-00 frame or AC6000-CART-00 cart. The compact dimensions (17.9" H x 16.0" W x 8.8" D for enclosed models) allow flexible integration into control panels or machinery. With a 1-year warranty and UL 1998 compliance, the SB5032-301-0 delivers reliable electrical safety without compromising operational efficiency. Ideal for applications requiring fixed 20 mA trip levels, this GFCI is a critical component for personnel protection in manufacturing, construction, and utility environments.
