Product details

Contact configuration and switching capacity

The LA1LB0341 is a TeSys auxiliary contact block providing two normally-open and two normally-closed instantaneous contacts, plus a separate set that operates only when the control knob is in any position other than auto or when tripped on short-circuit. Switching capacity varies by duty: in AC-15 at 220–240 V it handles 6000 VA making and 600 VA breaking; in DC-13 at 24 V it switches 120 W making and 70 W breaking over 1,000,000 cycles. The full matrix of VA and W ratings across voltages is in the spec table.

Termination and wiring

Terminals are screw-clamp type accepting 1 mm² and 2.5 mm² conductors — two clamps per contact, which allows daisy-chaining or looping without a separate jumper.
