Application
The auxiliary contact blocks are used for the operation of auxiliary circuits and control circuits
for contactors A/AF95...AF1650
Description
Type of side mounted auxiliary contact blocks available:
● CAL18 instantaneous 2-pole auxiliary contact blocks with N.O. + N.C. contacts.
- Equipped with screw type connecting terminals delivered open.

1SFC101074F0201
● CAL18-RT for ring tounge connection available (mainly for traction applications).
● CEL18 instantaneous1-pole auxiliary contact block with N.O. or N.C. contact.
- Equipped with built-in microswitch for low current and low voltage levels (mainly for PLC outputs)
- Equipped with screw type connecting terminals delivered open.
- Protected against accidental direct contact, IP20
- Marked in accordance with relevant standards.
Mirror contacts
The CAL18-11, CAL18-11B and CAL18-11RT auxiliary contact blocks are designed to meet the
requirements for mirror contacts in IEC 60947-4-1.
In short this means: The normally closed auxiliary contact can not be in closed position simultaneously with
the normally open main contact. (AF1350/1650: Use two N.C. auxiliary contacts in series for mirror contact
function, one auxiliary contact block on each side of the contactor).
Fitting Details
Clipped onto the right or lefthand side of the contactor.
The CAL18-...B is a second auxiliary contact block for mounting in addition to a first CAL18 block, right or
lefthand side of the A145 ... A300 and AF145 ... AF1650 contactors.

CAL18 Electrical Durability for AC-15 Utilization Category
AC-15 utilization category according to IEC 60947-5-1 / EN 60947-5-1:
– making current: 10 x Ie with cos ϕ = 0.7 and U
– breaking current: Ie with cos ϕ = 0.4 and U
These curves represent the electrical durability of the add-on
auxiliary contacts in relation to the breaking current.
