KUL-5A11S-120

Power relays are electronic control devices used to switch on and off circuits at predetermined conditions. The KUL-5A11S-120 is a low-profile, slim-body high-load single-pole, double-throw (SPDT) DC power relay with a rating of 120 Amps at a voltage rating of 220V. This type of power relay can handle up to 2 Amps of current, making it suitable for use in various applications including control of high-power loads such as motors, pumps, solenoids, etc., and in switching applications requiring multiple SPDT relays.

The KUL-5A11S-120 consists of two main components: a control circuit and an electromagnetic contact system. The control circuit is the part of the relay that controls the switching of the relay and contains the coil, which is energized by an external DC voltage source. When the coil is energized, the current creates a magnetic field, which causes the movable contact to close according to specified conditions. The electromagnetic contact system consists of a permanent magnet and an armature. The armature is attached to the movable contact, and when the coil is energized, the armature moves to close the contact, allowing current to flow through the relay.

The KUL-5A11S-120 is designed as a single-pole double-throw (SPDT) relay, meaning it can switch between two contacts according to a predetermined condition. This type of relay is suitable for applications requiring, two separate circuits to be activated separately or at the same time. In addition, the KUL-5A11S-120 offers great protection against overload and short-circuits by providing a trip-free design. When overloaded, the contact remains open, preventing the flow of current until the overload is removed.

The KUL-5A11S-120 is used in a variety of applications such as motor control,heating and cooling control, lighting and power control, occupant safety systems, and for high-current switching in industrial and commercial settings. It is designed for DC voltage applications and is suitable for switching up to 2 Amps of current. It is also resistant to shock and vibration, making it suitable for use in harsh environments where reliability is a must.

In summary, the KUL-5A11S-120 is a low-profile, slim-body single-pole double-throw power relay, designed for high-current switching applications. It is rated for up to 2 Amps at a voltage of 220V and offers great protection against overload and short-circuits. The KUL-5A11S-120 can be used in a variety of applications, including motor control, heating and cooling control, lighting and power control, and occupant safety systems. It is suitable for use in both industrial and commercial settings and is resistant to shock and vibration.
