Panel-Mount Equipment Circuit Breakers
Mount these breakers, also known as supplemental protectors, through panels downstream from a branch circuit breaker to protect a single piece of equipment. They are rated UL1077 for protection against overloads and short circuits. These breakers can also be used as on/off switches. All are thermal, so they use the heat generated in overcurrent situations to trip the breaker.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Covers for rocker style breakers (sold separately) provide IP54 protection against limited dust and splashed water.
Covers for push-button style breakers (sold separately) provide IP65 protection against water projected from a nozzle.

Harsh-Environment Circuit Breakers
Built to resist vibration and corrosion in harsh environments, these circuit breakers protect against overload and short circuits in low-voltage automotive and other electronic applications. All are thermal, so they use the heat generated in overcurrent situations to trip the breaker.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Push-pull button and lever style breakers can be used as an on/off switch.
Place UL1077 rated breakers downstream from a branch circuit breaker to protect a single piece of equipment. They are also known as supplemental protectors.

Harsh Environment IEC Connectors with Power Switch
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.
