DIN-Rail Mount Ground Fault Circuit Protectors
Add ground fault protection to a circuit to minimize the risk of electric shock to workers and equipment if there is a current leak. These protectors meet strict UL 1053 standards for ground fault detecting devices. They will trip if they detect a current leak above 30mA. However, they do not protect against overloads. Pair them with a circuit breaker to fully protect a circuit. Commonly used in electrical enclosures, these protectors mount directly to DIN rail.
Breakthrough current is the maximum current that the circuit protector can safely stop in the event of a short circuit.

Ground-Fault Monitoring Relays
Detect and mitigate ground faults to prevent harm to equipment, circuits, and people. These relays monitor the differential between incoming and outgoing current, also known as residual current. When the balance is off, they trip and cut power to the circuit. These relays are highly sensitive, so you can trust them to de-energize faulty circuits before a minor issue becomes a major one. Rated IP20, they have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on 35 mm DIN rail (also known as DIN 3 rail) for fast installation.
These relays require a current-indicating ring (sold separately) to operate. Choose a ring that is large enough for your lines to pass through. Feed the lines of the circuit through the center of the ring and connect the indicating ring output to the relay.
Relays with spring-clamp terminals connect and disconnect to wire without screws. Because they don’t have screws, there’s less of a risk that they will loosen over time, even when they’re under vibration.
Relays with IO link can be programmed, monitored, and reset remotely by connecting them to a programmable logic controller (PLC), human-machine interface (HMI), or computer. If you want to program them locally, they have a keypad.
Relays with knob adjustments have knobs right on the front where you can set your trip current.
Relays with an LED indicator show the status of your relay, so you know it is wired correctly and when it is actuated.
