The test is designed to determine how much voltage the circuit breaker can handle without the terminals overheating, i.e. 100 ˚C above ambient temperature.
Continuous = 275A | Short time = 455A | Shock = 1250A
Continuous = 1 hour | Short-term load = 5 min. | Shock load = 10 sec.
Key can be removed.
Terminals and nuts: tinplated copper.
Spark/ignition protected.
