JFD - Ultrathermics Circuit Breaker

The totally enclosed design offers full protection to the surface operator from unintentional contact whilst also shielding them from the visual arc spark during the breaking of the circuit. The single switching action breaks both poles of supply thereby rendering the cutting / welding equipment safe.

The Ultrathermics circuit breaker is a two pole, 630 amp AC or DC circuit breaker for direct surface control of underwater cutting and welding operations.
