Use these circuit breakers upstream from small transformers, lighting, and control circuits. They meet UL 489 requirements for branch circuit protection. All are thermal/magnetic—breakers trip when heat is generated by sustained, low-level overload current, but will trip quickly when the magnetic field in the coil senses a high-current short circuit. Mount directly to DIN rail.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Alarm (sold separately) sends an audible signal when the breaker is tripped.

Rated IP67, these connectors create a dust- and watertight seal where they fit into the housing of power supplies, appliances, and other electronic devices. Instead of hardwiring your devices, these connectors let you plug in a standard IEC power cord and turn the power on and off with a built-in switch. Wire these connectors using the quick-disconnect terminals; they slide together with matching terminals on your wiring for a secure hold that's also easy to pull apart to make repairs. The terminals are on the back of the connector, so the wiring stays inside your device.
To protect your devices, these connectors have a thermal circuit breaker that uses the excess heat when there’s overcurrent to trip the breaker and cut power. If there’s a short circuit, the breakers can safely stop up to a 2,000-Amp breakthrough current. These connectors also have Class I shock protection, so they’re insulated and have a protective ground.
These connectors meet UL 94 V-0, which means they self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping. They’re also UL and C-UL recognized components, and CE and ENEC marked, so they meet stringent safety standards.
