What does co mean for relays?

The type CO relays consist of an overcurrent unit (CO), an indicating contactor switch (ICS), and an in- dicating instantaneous trip unit (IIT) when required. The principal component parts of the relay and their location are shown in Figures 1 through 5. 2.1.

What are co contacts?

Change-over (CO), or double-throw (DT), contacts control two circuits: one normally-open contact and one normally-closed contact with a common terminal. It is also called a Form C contact or "transfer" contact ("break before make").

What is NC and NO?

Normally Open (NO) and Normally Closed (NC) terms refer to type of dry contact or wet contact. Put very simply, a Normally Open sensor will have no current when in a normal state but when it enters an alarm state it will have +5V applied to the circuit.

What does OC mean in electrical?

OC or O/C Overcurrent or open circuit.

What is the function of the O C relay?

Overcurrent relays are electrical protection devices that are designed to open or trip a circuit when the current flowing through it exceeds a certain level, but on the higher side.

What is o C and E F relay?

The combined overcurrent and earth-fault relay REJ 515 is a secondary relay which is connected to the current transformers of the object to be protected. The overcurrent unit and the earth-fault unit continuously measure the phase currents and the neutral current of the object.

What is 2 form C contact?

Form C refers to a Single Pole-Double Throw (SPDT) contact, which means that there is one common point connected to one normally open-end and another normally closed contact. "2 Form C" refers to two "Form C contacts," so on and so forth.

How many contacts does relay have?

A simple electromagnetic relay consists of a coil of wire wrapped around a soft iron core (a solenoid), an iron yoke which provides a low reluctance path for magnetic flux, a movable iron armature, and one or more sets of contacts (there are two contacts in the relay pictured).

How many contacts does A relay have?

Each set has 3 contacts, a Common (C), a Normally Open (A) and a Normally Closed (B).

How many amps before you need A relay?

You will often see circuits carrying less than 20 amps switched directly, while circuits of 30-40 amps can sometimes be directly switched but will often be controlled by relays. Anything above 40 amps is pretty much always on a relay.
