DAYTON 5Z546 Relay DPST-NO 6 Pins 120VAC

Dayton 5Z546 open power relay is designed to switch motor loads in elevators, machine tools and air handling & HVAC equipment.

Working Mechanism:

• A power relay's basic design includes an electromagnet (coil and iron core), an armature, a spring and one or more pairs of contacts.
• A small current flows through the input circuit when normally open (NO) contacts are used, activating the electromagnet.
• The magnetic field created attracts the armature, which moves the contacts together, completing the second circuit and allowing a large volume of current to flow.
• When the power source is removed, the armature is no longer attracted and a spring returns it to the rest position, allowing the contacts to separate and the flow of electricity in the second circuit to stop, effectively turning off the device.
• In order to operate AC relays, the voltage must be at least 85% of the nominal voltage.

Features:

• The unit comes with silver cadmium oxide contacts.
• It has a moulded thermoset plastic base to provide low arc & creep, as well as high dielectric strength & heat resistance.

Standards and Approvals:

• UL
• CSA
• CE

Frequently Asked Questions:

Q. What is a DPST switch used for?

A. A DPST switch can isolate both the live and neutral connections, so it is often used to switch the mains electricity.

Q. Why is silver cadmium oxide used for contacts?

A. Owing to their high conductivity, arcing resistance and wear resistance, silver cadmium oxide contacts are used for low-tension devices.

Q. What is the mounting orientation of Dayton 5Z546?

A. Dayton 5Z546 open power relay can be surface mounted.
