Float switch SKF1A-20 T0-SKF1A-20

Float switches – reliable installation protection

The SKF1A-20 float switch is a device designed to automatically switch off equipment when the liquid level rises. This is particularly important in pumping systems, retention tanks, or in installations where liquid level control is crucial for safety and proper operation. This model, with a 20-meter cable length, provides flexibility in installation and adaptation to various applications.

Construction and principle of operation

The switch uses a hermetically sealed float contact that reacts to changes in position. As the float rises, the contact switches, breaking the electrical circuit and turning off the connected device. The construction based on solid materials guarantees long-lasting and trouble-free operation even in difficult environmental conditions. The IP68 protection class ensures resistance to water and dust ingress, enabling safe use in humid and submerged environments.

Applications and benefits

The SKF1A-20 float switch finds wide application in both domestic and industrial installations:

• Pump protection: Prevents the pump from running "dry", which could lead to damage.
• Liquid level control: Maintains the optimal liquid level in tanks, swimming pools or septic tanks.
• Process automation: Enables automatic control of devices depending on the liquid level.
• Overfill protection: Protects against liquid leakage and potential flooding.
• Simple installation: Thanks to the 20-meter cable, the switch can be easily adapted to a specific installation.
• High reliability: Solid construction and hermetically sealed contacts ensure long-term operation without frequent repairs.
• Versatility: Suitable for different types of liquids – water, sewage, oils (check material compatibility).

The device is characterized by a rated current of 10A and a rated voltage of 250V AC, making it suitable for most standard applications. The switching contact ensures reliable and dependable operation in control circuits.
