The 1617787-4 Power Relay has a UL recognized initiation and a short time resistance of up to 500V. It is also designed for an operating temperature range of -20C to +80C. Furthermore, this power relay is designed to protect sensitive electronic components from short circuit and overheating.

1617787-4 Working Principle

The 1617787-4 power relay works on the principle of a contact pair in which a conducting armature switch is connected to the base. The armature switch is connected to the base through a contact-bearing surface. The movement of the armature switch is accomplished by a magnet or electro-magnet. The contact-bearing surface is insulated from the base, and as a result, electric current flows through the contact pair.

When supplied with a control voltage, electric current will flow through the contact-bearing surface and the armature switch will move to the "open" position, allowing electrical current to flow through the coil leading to the switching of the load. When the control voltage is released, the armature switch moves back to the "closed" position, and the load is switched off. Depending on the type of application, the movement of the armature switch may be manual, automatic, magnetic, or digital.

The working of the 1617787-4 power relay involves the movement of a contact pair for switching or controlling the electrical current. This contact pair consists of two types of contacts- a stationary contact that is connected to the base and a movable contact that is connected to the base through a contact-bearing surface. The contact-bearing surface is insulated from the base so that electric current flows through it. When provided with a control voltage, the movable contact is switched, allowing electrical current to flow through the coil.

The 1617787-4 power relay is designed to control and switch various electrical devices. These relays are known for their high current capability and their compact size. This power relay has a UL recognized initiation and a short-time resistance of up to 500V. Furthermore, these relays offer low electrical noise immunity and can be utilized in applications requiring both AC and DC operation.
