The housing, made of glass-fibre reinforced
polyamide, fulfils the demands required for
isolated low-voltage switching and contact
devices. Due to its pin shaped geometry, the
particularly robust, separate actuator is suit-
able for use in tolerance-burdened protec-
tive equipment. Optional actuators, which
can be adjustable or flexibly mounted, guar-
antee a high mechanical loading capacity.
