Overview

The ABB ISR150-156SS Industrial Strain-Relief Fitting is a corrosion-resistant, stainless steel solution engineered for heavy-duty industrial cable protection in demanding environments. Designed with a 1-1/2 inch NPT hub, this fitting accommodates cables ranging from 33.91 to 39.37mm (1.335 to 1.550 inches) in outer diameter, ensuring secure strain relief and cable management in high-vibration or high-tension applications. Constructed from type 303/304 stainless steel, the fitting resists corrosion and maintains structural integrity in harsh conditions, including marine, chemical processing, and food processing applications where exposure to moisture, salt, or corrosive agents is common. The recessed O-ring design provides a long-term watertight seal, preventing ingress of liquids, dust, and contaminants while maintaining electrical safety. The included stainless steel mesh grip enhances cable retention by distributing clamping force evenly, reducing the risk of pull-out or damage to the cable jacket. With a 65.53mm outer diameter, the fitting integrates smoothly into NEMA 4 enclosures when paired with the correct gasket, ensuring compatibility with standard industrial enclosures. Certified to CSA and UL standards (File No. E76954, LR32159), this fitting meets stringent safety requirements for electrical installations, including UL 50E and CSA C22.2 No. 94.1. The ISR150-156SS is ideal for manufacturing, automation, industrial control systems, and other applications where reliable cable strain relief and compliance with safety regulations are critical. Its durable stainless steel construction and precision-engineered design deliver consistent performance in high-stress environments, reducing maintenance needs and downtime.
