127V ac Instantaneous 4 C/O Relay Circuit Trip

Introducing Schneider Electric instantaneous range of relays, they are commonly referred to as the RHN series. This range of plug-in automation relays is on an RHZ-21-type base. The face on the front of the relay pivots and has three different functions. These are Removal latch, dust protection and protection from moving components as well as stop-locking.

• Each instantaneous relay from the RHN series self-locks into the base through snap-fitting
• Robust and hard-wearing
• Compact in design and in size

A relay is an electrical switch that is operated by electrical pulses, their primary function is to open and close a circuit. When power passes through a circuit, a relay switches position (usually from NC to NO) using an internal coil which generates a magnetic force. This force then holds the relay in a NO position, when the current is switched off the relay returns to the NC position. This function is what makes these non-latching relays perfect for push-button applications such as keyboards and micro-controller input buttons.
