Auxiliary contact block for TeSys contactors
The LA1LB015: It is designed for general-use control circuits, rated 10 A conventional free air thermal current (Ith) and 690 V rated insulation voltage (Ui) per IEC 60947-5-1.
Making capacity and operational power ratings
The making capacity varies by circuit type and voltage: for AC-15 duty at 220–240 V AC it is rated 6000 VA, while at 440 V AC it reaches 7000 VA. For DC-13 duty at 24 V DC the making capacity is 800 W, and at 440 V DC it is 220 W. Rated operational power in VA and W is specified across multiple voltage levels and endurance cycles — for example, 600 VA at 220–240 V AC-15 for 1,000,000 cycles, and 70 W at 24 V DC-13 for 1,500,000 cycles.
Termination and switching capacity
The block uses two screw clamp terminals sized for 1 mm² and 2.5 mm² conductors. Minimum switching capacity is 0.6 VA at ≥ 17 V and 0.01 A, which means it can reliably switch low-energy signals in PLC or relay logic circuits without contact wetting issues.
The LA1LB015 is listed as obsolete by the manufacturer. It is available through independent distribution channels; quantities are confirmed at RFQ.
