KTA7-25S

Sprecher + Schuh’s KTA7-25S manual motor controller family offers higher interrupting capacities (KAIC ratings) and improved Type 2 Coordination and Type E (life after short-circuit). The KTA7-25H/32H offers the option of higher short-circuit current ratings (SCCR) than the standard interrupting capacity of the KTA7-25S/32S Motor Controllers. KTA7 is also available in frames up to 45A. KTC7 can be used with High Efficiency motors. KTB7 Magnetic Only controllers can be combined with CA7 contactors and CEP7 overloads to provide additional features.

Every KTA7 device is individually calibrated at the factory for the smallest and largest current it can handle. When coupled with automatic ambient temperature compensation over a range of -25°C to +60°C, very accurate thermal overload protection is obtained. In addition, the KT7 is a Class 10 device… it trips within 10 seconds under locked rotor conditions (6 x FLA). This better protects today’s T-Frame motors.
