Three-phase leakage breaker 30A

The Fuji SG53C is a three-phase leakage protection circuit breaker rated at 30 A. It is designed for electricians and maintenance crews who need reliable ground-fault detection on three-phase supplies. The red-finished unit ships as a single pack in a box.

Sustained-load behaviour

Under continuous operation the breaker monitors all three phases for leakage current and trips when a fault exceeds its threshold. The mechanism is built to maintain calibration during prolonged energised periods without nuisance tripping. A three-year parts warranty and one-year labour coverage back the sustained reliability.

Upgrade context

This device replaces older single-phase or non-leakage breakers where three-phase ground-fault protection is now required. The jump is worth it when an installation moves to three-phase distribution or when regulations demand dedicated leakage detection. It does not suit buyers who need adjustable trip curves or integrated over-current protection beyond the fixed 30 A rating.

Questions about this item

How much heat does the 30 A breaker dissipate during continuous three-phase operation?

The SG53C is a protection device, not a load, so its own heat output is negligible compared with the circuit it safeguards.

What supply voltage and wiring must already be in place for the three-phase 30 A unit to function?

A three-phase mains supply rated for at least 30 A per phase and correctly sized conductors are required before installation.

Will the SG53C coordinate with an older Fuji breaker rated at 53 A on the same distribution board?

Coordination depends on the time-current curves of both devices; consult the manufacturer's selectivity tables for the 30 A and 53 A models.
