Contactors
Overview - Bulletin 100-M
Minimum Space Requirements for Accessories
Auxiliary contact blocks and timers can be mounted onto the contactor
without requiring additional panel space.

Positive Guidance of the Contacts
Positive guidance of the contacts according to IEC 60947-5-1 is given
when it is ensured, that N.C. and N.O. contacts can never be closed at
the same time. Therefore a minimum opening distance of 0.5 mm is
prescribed in the event of failure. All contacts in the basic device are
positively guided as well as the normally closed contacts in the auxiliary
contact block except Bulletin 700-MB bifurcated contacts. This permits
use within safety controls.
High Contact Reliability
Bulletin 100-M Miniature Contactors are rated for extra-low voltage. In
addition to the isolation of the contact housing, high contact reliability is
ensured by the special design of the auxiliary contacts:
• cross-stamped in the main contactor
• in the auxiliary contact block and in the bifurcated contacts (see chap-
ter 8, Bulletin 700-M timers), H-contact bridges with constant sliding
rolling motion and 4 multiple current path.
