The Siemens 17DSF92NF Non-Fusible Combination Starter is a versatile and reliable electrical component designed for use in commercial and industrial applications. This starter is suitable for motors with a NEMA frame size of C or D and a rated current of up to 200 amperes.
The non-fusible design of this starter means that it does not include an internal overload relay or fusible link. Instead, it relies on external overload protection, such as a separate overload relay or a circuit breaker. This makes it an ideal choice for applications where the motor's starting current is significantly higher than its running current, or where the motor is subjected to frequent starts and stops.
The 17DSF92NF is a combination starter, meaning it is capable of both direct-on-line (DOL) and reduced voltage starting. For DOL starting, the starter simply closes the contacts to apply power directly to the motor. For reduced voltage starting, the starter can be used in conjunction with a soft starter or a variable frequency drive (VFD) to gradually bring the motor up to speed, reducing the electrical stress on the motor and extending its lifespan.
This starter is constructed from high-quality materials, including a copper-free aluminum frame and brass contact material. It features a robust mechanical design with a rugged cast iron housing and a durable bakelite knob. The contacts are silver-plated to ensure low resistance and long life, while the insulation is rated for a maximum operating temperature of 105 degrees Celsius.
The Siemens 17DSF92NF Non-Fusible Combination Starter is designed to meet the rigorous requirements of UL 1077 and CSA C22.2 No. 1 standards for safety and performance. It is also RoHS compliant, meaning it contains no restricted hazardous substances.
Installation of the 17DSF92NF is straightforward, with clear markings on the starter indicating the line, load, and ground terminals. It can be mounted in a variety of orientations, including horizontal or vertical, using the included mounting brackets. The starter also features a convenient test button, which can be used to verify the proper operation of the contacts before applying power to the motor.
In summary, the Siemens 17DSF92NF Non-Fusible Combination Starter is a high-performance and versatile electrical component suitable for a wide range of commercial and industrial motor applications. Its non-fusible design, combined starter functionality, and robust construction make it a reliable and cost-effective solution for demanding electrical systems.
