MK3PNV-5-I-AC220

The MK3PNV-5-I-AC220 is a power relay capable of handling loads greater than 2 Amps. It is a single-pole normally open (SPNO) contact rated switch – meaning it generally remains in an open (non-conductive) state until an external force is applied to the contacts, causing them to close (conduct). This relay type is used in a variety of applications, including industrial machinery, automation, and robotics.

Mechanical Construction

The MK3PNV-5-I-AC220 is constructed from strong, lightweight materials, such as metal and plastic, that help to ensure long-term reliability and durability. The external housing is designed to protect the internal components from external influences like dirt, dust and water. The relay is fitted with two 6 mm push-bars on the outside, which are used to manually activate and reset the contact. Inside the relay is an adjustable spring that holds the contacts in the open position.

Operating Voltage

The MK3PNV-5-I-AC220 relay is rated to operate at an input voltage of 220v AC. This is the same voltage used for traditional residential outlets throughout North America. The relay is suitable for applications in both household and industrial settings. The maximum current that can be handled by the relay is 2 Amps.

Electrical Connections

The MK3PNV-5-I-AC220 relay has two terminals, the common (COM) terminal and the normally open (NO) terminal. The common terminal is the return connection for electrical current and is always connected to ground. The normally open terminal is the connection point for the electrical current when the contact is closed. The contact is opened when the external force is removed from the push-bars and the relay is reset.

Working Principles

The MK3PNV-5-I-AC220 is a single-pole normally open (SPNO) contact rated switch. This type of contact has two states, normally open and momentarily closed. The relay is normally in an open state which means that electrical current will not flow through the contact. When an external force is applied to the contacts, the spring-loaded armature is pushed down, causing the contact point to close, and allowing electrical current to flow. When the force is removed, the armature snaps back into place, opening the contact and preventing electrical current from flowing.

Applications

The MK3PNV-5-I-AC220 is well-suited for applications such as industrial machinery, automation, and robotics. It is also used in motor control systems, as well as for load switching and similar operations. This type of relay can be used to control the voltage supplied to electric devices, allowing user to quickly switch between different settings without having to manually adjust the voltage. The MK3PNV-5-I-AC220 is also suitable for applications such as circuit-breakers and motor starting, enabling the user to remotely control and switch electrical current.

Conclusion

The MK3PNV-5-I-AC220 power relay is an efficient and reliable solution for applications demanding greater than 2 amps of load. It has two terminals, an adjustable spring armature which holds the contacts in the open position, and a strong and lightweight housing to protect internal components from external elements. This type of relay is suitable for use in both residential and industrial settings, and can be used for controlling voltage in electric devices, load switching, and circuits-breaker applications.
