2 Product description
The COMBISTOP type 38 brake is an electromagnetically actuated dual-surface
spring-applied brake for dry running.The standard series of dual-surface spring-applied
brakes are COMBISTOP N and H in two versions.
The brakes are optionally designed for dynamic applications with braking processes at
high speed (COMBISTOP N) and for static applications, i.e. braking at speeds and safe
holding of loads (COMBISTOP H).
Using the optional hand release (version 13N/DEN and 13H/DEH), the brake can be
manually opened even in the event of a malfunction.
COMBISTOP D stands for double safety and includes a series of double brakes pre-
pared for tasks with redundant brake circuits. The mechanical design with two com-
pletely independent safety spring-applied brakes meets the requirements of DIN 56950
(BGV C1).
The brakes are delivered ex works with preset air gaps ready for installation. Extensive
design measures reduce switching and running noise to a minimum.

2.1 Intended use

Spring-applied brakes are used to brake rotating masses or to hold shafts.
The operational reliability of the brake is only guaranteed when used according to spec-
ified application. In this context, specified application means that the brake is used for
the ordered and confirmed purpose.
Any other use is considered a breach of specified application. It may pose unforeseea-
ble risks and is solely and exclusively the responsibility of the operating company.
The technical data and the information on the connection conditions must be taken from
the nameplate and the instructions for use and must be observed. Any use beyond the
technical specifications is also considered as not specified.
The actual use of the brake in the target products is beyond KEB Automation KG's con-
trol and, therefore, shall be exclusively within the operating company's responsibility.
Restriction
If the product is used in machines which work under exceptional conditions or if essen-
tial functions, life-supporting measures or an extraordinary safety step must be fulfilled,
the necessary reliability and security must be ensured by the machine builder.
