ABSTRACT:
A circuit breaker including a pyrotechnic element configured to ablate, tear, or cut a portion of the circuit. The portion of the circuit to be broken may be formed to be readily broken and/or may be a current load-based fuse. Also, the circuit breaker may be configured to ensure predictable progressive lateral tearing of the portion of the circuit to be broken; the circuit breaker may optionally be configured so that substantially all of the pyrotechnic element's output is focused on breaking the circuit; and the circuit breaker may optionally include a positive displacement mechanism that, after actuation of the pyrotechnic igniter, prevents the circuit breaker from inadvertently re-closing.
