Schneider Electric TeSys D LC1D Contactor, 24 V dc Coil, 4-Pole, 25 A, 2NO + 2NC, 690 V ac

Choose this contactor from Schneider Electric to control the forward and reverse operation of resistive loads. Its 4-pole configuration means that this component can handle 4 circuits at the same time, making it a good choice for space efficiency. It has a 6kV rated impulse withstand voltage to let it cope with sudden power spikes without deformation. Integrated fuses provide short-circuit protection so you're safe from electric shocks. You'll find devices like this used in domestic and light industrial applications.

• IP20 (ingress protection) rating indicates protection from dust and objects larger than 12mm
• Low power dissipation of 1.56W per pole for energy efficiency
• Comes with a front cover for added surface protection
• Mechanical life of 30,000,000 cycles for long-term performance
• Light weight of 365g, so it's easy to handle

• Electric furnaces
• Industrial lighting
• Heating equipment

The most important maintenance for this contactor is cleaning. Simply blow away dust with a low-pressure stream of dry air. You should also check the unit's terminals for loose connections caused by vibration and tighten them if necessary. This can prevent sparks and overheating.
