Product Description
The Sprecher and Schuh KTA7-25H-10A motor circuit breaker offers phase loss protection, a rotary on/off handle and is adjustable from 6.3 to 10 AMPS. This high interrupting capacity motor starter comes with class 10 tripping, which cuts power in 10 seconds or less in the event of an over current condition, and has screw terminals and DIN rail mounting for easy installation and removal. Front and side mounted auxiliaries are available for the KTA7-25H-10A along with under voltage trips to suit any applications needs.

In the event of a short-circuit, the contacts are opened by magnetic, non-adjusting tripping elements in times approaching 2/1000 of a second. This results in the extremely rapid buildup of an arc voltage which limits the current of the short-circuit to a very low level. Because of this superb current limiting capability, KTA7-25S Motor Circuit Controllers have a short circuit capacity of up to 65kA at 480Y/277V and up to 47kA at 600Y/347V
Sprecher + Schuh’s KTA7 series of motor circuit controllers are some of the most versatile and technologically advanced control products available today. In one small package, KTA7s combine the functions of:
• Current limiting short circuit protection
• Class 10 thermal overload protection
• Switching and Signaling
These devices can be used in a wide variety of control schemes that reduce panel space, simplify installation and eliminate the need for more expensive equipment.
