AMPHION™
Solid State Relays
DESCRIPTION
The 10747 Solid State Relay (SSR) combines the functions of a power
contactor and an arc fault circuit breaker into one small and efficient module.
The SSR fits in a standard M12883/48-02 socket and can switch up to
25 A at 28 VDC. This device can switch inductive or incandescent loads at
the full rated current. There is also no wear out mechanism and the “on”
resistance does not increase with age providing a highly reliable solid state
alternative to mechanical relays.
ARC FAULT PROTECTION
The circuit breaker has the ability to detect and trip on intermittent arc
faults produced by wire insulation failure.
FEATURES
UNIQUE FAILSAFE DESIGN
Adjustable trip curve
Unlike other solid-state products, the SSR contains patented circuitry that
prevents a failure in a short-circuited condition. This means that a failure
will not cause a critical load to remain powered in an unprotected and
uncontrolled manner.
