Eaton FAZ-B30/1-SP Circuit Breaker

The FAZ-B30/1-SP is a UL 1077 recognized supplementary protector. It is designed for use within appliances or electrical equipment where branch circuit protection is already provided or not required, and cannot be used as a direct substitute for a UL 489 branch circuit breaker.

The B curve indicates that the instantaneous trip point is 3 to 5 times the continuous current rating. This makes it ideal for resistive or slightly inductive loads where low levels of inrush current are expected, such as control wiring, PLCs, and business equipment.

This miniature circuit breaker is designed to snap directly onto a standard 35mm DIN rail, making it suitable for control panel assemblies.

This breaker features standard box terminals designed to accept multiple conductors. The terminals include captive screws that cannot be lost during wiring and installation.

Yes, this supplementary protector is reverse feed capable, allowing power to be supplied from either the line or load side terminals.

Yes, it features a color-coded indicator that provides immediate visual confirmation of the device status, showing red for ON and green for OFF.

Yes, although not strictly required for UL 1077 supplementary protectors, this FAZ series breaker features a current-limiting design that interrupts fault currents within one half cycle, reducing peak let-through energy to protect downstream circuits.

Yes, the Eaton FAZ series supports snap-on accessories, including auxiliary contacts, shunt trips, and bus connectors, which can be field-installed to expand control panel functionality.

The -SP suffix indicates that the breaker is supplied in single packaging, which is standard for select amperages of single-pole FAZ curves.
