Integration and fit
The 3RT1936-4BA33: This link snaps onto the front of a 3RT2.3 contactor — no separate terminal block needed for the parallel connection. The 3-pole design matches the contactor's main pole layout; you wire the load-side power bus through the link rather than through individual terminals. Because it omits touch protection, plan for additional shrouding or panel-door interlocking if the assembly is accessible during operation. Mounts in the same DIN-rail footprint as the base contactor.
