Overview

The Littelfuse SB5032-311-0 Industrial Shock Block® is a critical safety device designed for robust overcurrent and ground-fault protection in industrial settings. With a substantial supply voltage rating of 600V, this unit ensures reliable operation in demanding electrical systems. A key feature is its selectable trip level functionality, allowing users to precisely set the ground-fault trip point from 6mA up to 100mA, in 10mA increments. This adjustability is crucial for tailoring protection to specific equipment sensitivities and regulatory requirements, minimizing nuisance tripping while maximizing safety. The SB5032-311-0 employs an inverse time trip curve, a standard for effective fault interruption that balances speed with the avoidance of transient overloads. Its enclosure meets NEMA 4X standards, offering protection against dust and water ingress, and is lockable for added security. Operating within a wide temperature range of -35°C to +40°C (derating to +66°C), it is suitable for diverse environmental conditions. Wiring requirements accommodate up to 2/0 AWG conductors, facilitating integration into existing infrastructure. The device is UL Listed as a GFCI (enclosed models) and a cULus Listed EGFPD, meeting stringent safety certifications. Applications include machinery, automation systems, process control, and any industrial environment where personnel and equipment protection against ground faults is paramount. The SB5032-311-0 is engineered for direct inline installation between incoming power or an existing overcurrent protection device and the load. Its compact dimensions (enclosed: H 453.8 mm, W 406.2 mm, D 223.3 mm) allow for efficient panel space utilization. Trust Littelfuse for dependable electrical safety solutions.
