Electric Contacts for Relays

 

The contacts of an electromagnetic relay are responsible for creating and breaking connections in electrical circuits. These contacts must be able to handle both the inrush current as well as the nominal-load current, which depend on the power they are required to carry and the characteristics of the circuit being used. The overall performance of a relay is determined by its contact arrangement, mechanical construction, and most importantly, the suitability of its contact materials.

Relays have various types of contact arrangements that are used for making and breaking electrical circuits. Each arrangement has different capabilities to allow them to safely transmit electricity through varying conditions.  These contacts are made from materials such as metals or alloys that must be suitable for the conditions, under which they are expected to be used.

The Types/abbreviations commonly used for relay contacts are listed below.

• SP - Single-Pole
• SB - Single-Break
• ST - Single-Throw
• DB - Double-Break
• DP - Double-Pole
• DM - Double-Make
• DT - Double-Throw
• NO - Normally Open
• 3P - Three-Pole
• NC - Normally Closed
• 4P - Four-Pole

We can provide customized relay contacts as per your drawings.
