L Series Controls
The L series, L7, LM7 and LM8, is a family of fixed setting temperature limit controls whose design is failsafe. The L7 is auto reset, whilst LM7 and LM8 are manual reset. The operating temperatures are factory set and non-adjustable by the customer. Settings are available between 50 and 160 °C with capillary lengths from 450 – 2000 mm (1000 mm standard). The L7/LM7 are SPST (single pole single throw) and LM8 is DPST (double pole single row).
