FCA-125-BY1

The FCA-125-BY1 is a power relay that can handle loads of more than two amps. As a result, it is often used in applications where higher current power needs to be switched. It is suitable for direct current (DC) and alternating current (AC) loads. It is available in several models, such as normally open, normally closed, and double contact types.

The FCA-125-BY1 is a single pole / single throw (SPST) type relay. It has five terminals, a normally open pole, a normally closed pole, and three coil terminals. The coil terminals are connected to an external coil, which can be energized to turn the switch on or off.

When the coil is not energized, the relay is normally open, meaning that the contacts inside the switch are at a distance and no electrical current can flow. When the coil is energized, the armature is drawn towards the contacts and closes the switch, allowing current to flow. When the coil is once again de-energized, the armature returns to its normally open position.

The FCA-125-BY1 is capable of carrying current up to 16 Amps, depending on the model. It has a voltage rating between 0 and 300 volts AC and 0 and 60 volts DC. This makes it suitable for a variety of applications, such as motor control, sound and light systems, and home automation systems.

The FCA-125-BY1 is also designed with safety in mind. It is equipped with a varistor in parallel with the coil for over-voltage protection and has a low frequency surge rating of 4 kiloamps (kA). It also features an internal safety shutter, which prevents accidentally touching the relay’s energised contacts.

In summary, the FCA-125-BY1 is a versatile and reliable power relay that can handle loads over 2 Amps. It can be used in various applications, including motor control, sound and light systems, and home automation systems. It is also designed with safety features such as a varistor for over-voltage protection and an internal safety shutter.
