Description
Schneider Electric LADN20 TeSys D Auxiliary Contact Block is an electrical component used in control circuits of electrical systems. It is a modular unit that is typically attached to a main contactor or a relay. The primary function of an auxiliary contact block is to provide additional contacts that can be used to control or monitor other devices in the circuit.
2NO typically refers to a block that contains two Normally Open (NO) contacts. These contacts are electrical switch elements that are normally in an open state, but they close when activated. Auxiliary Contact Block is designed to be mounted on the front panel or surface of a control panel or electrical enclosure. It is equipped with terminals where wires can be secured by tightening screws. This provides a reliable and secure connection method for electrical wiring.
In summary, Schneider Electric LADN20 TeSys D Auxiliary Contact Block is a component used in electrical systems to provide additional Normally Open contacts. It is designed to be mounted on the front surface of a panel and features terminals that allow wires to be securely connected using screws. This type of component is commonly used in control circuits and automation systems.
