Star Teck^® ST90 series90-degree Teck fittings

In the fast-paced world of industrial automation and connectivity, the demand for robust, reliable, and efficient solutions is ever-growing. ABB’s ST90 series is an extension to the Star Teck Family which incorporates everything you need for a 90-degree cable termination. Designed to meet the rigorous demands of the industry, providing reliability, quality and safety.

Features and Benefits

The ST90 series is engineered to provide secure connections, ensuring optimal performance and safety in harsh environments. Here are some key features:

• Superior sealing gasket for enhance ingress protection: Type 4, 4X and 6P
• Locking striations prevent loosening of the fitting once installed while biting into enclosure to achieve better binding
• Copper-free aluminum, hardened for higher strength
• Power-Grip grounding ring
• Dual bushing system for broader cable range

Faster and Simpler to Install

One-piece Design

• The three components shown in photo 1 – Star Teck fitting, rigid elbow and sealing gasket – are an integral part of the ST90 fitting’s unique, one-piece design (photo 2)

Less space and cable required

• Photo 3 shows the additional space and cable required to accommodate a minimum bend radius in a code-compliant installation. A cable terminated with an ST90 fitting has a bend radius that is 80% to 90% smaller than that of corresponding cables (photo 4).
• Photo 5 shows a cable installation infringing on minimum bend radius as stipulated by the CEC (above).
• Photo 6 demonstrates the same termination done with an ST90 series Teck fitting.

With less separate components to purchase and stock, ST90 fittings simplify product selection and SKU management. The Canadian Electrical Code stipulates when installing armoured cables, it’s required that the bend radius of the inner edge of the cable is no less than 6 times the external diameter of the cable. For shielded cables, the bend radius needs to be at least 12 times the external diameter as per the regulations.
