FAQ:
Q: What is the current capacity of a 12 volt relay?
A: Typically 12V for passenger vehicles and small craft but also available in 6V for older vehicles and 24V for commercial applications (both auto and marine). This is the current carrying capacity of the high current circuit (s) and is normally between 25A and 40A, however it is sometimes shown as a dual rating on changeover relays e.g. 30/40A.
Q: Can a make and break relay be used as a changeover relay?
A: Tip: you can use a changeover relay in place of a make & break relay by just leaving either the NO or NC terminal disconnected (depending on whether you want the circuit to be made or broken when you energise the relay).
Q: Where is the diode located on a 12V relay?
A: Terminal numbering. The diode will always be installed in the relay with the stripe on the diode body facing towards terminal 86 (reverse biased) and it is important that +12V is connected this terminal, not 85 (as per the DIN standard) or the diode could be damaged.
Q: Why is ISO mini relay called make and break?
A: The ISO mini relay we have looked at above has 4 pins (or terminals) on the body and is referred to as a make & break relay because there is one high current circuit and a contact that is either open or closed depending upon whether the relay is at rest or energised.
