Sprecher & Schuh KTA9-32S-16A Motor Protection Circuit Breaker

Sprecher + Schuh KTA9-32S-16A Motor Protection Circuit Breaker is a compact, three-phase motor protection device with a 16 A nominal current rating, designed to interrupt motor current during overload or short-circuit events and protect both motor windings and power wiring. It is part of the KTA9 base-unit family of Motor Circuit Controllers and employs an adjustable thermal overload alongside fixed magnetic tripping, specified as Adjustable Thermal/Fixed Magnetic (14 x In), enabling tailored protection to match motor load profiles. The KTA9 family supports multiple voltage classes used in industrial power systems, including 230V, 400/415V, 500V, and 690V, allowing this 32S-16A variant to be used across diverse regional networks. Typical applications include protection in motor control panels for machines, conveyors, fans, pumps, and other three-phase motor-driven equipment where precise 16 A protection and quick interruption of fault currents are required.
