Siemens Q160 Miniature Circuit Breaker

Yes. Siemens acquired Murray and phased out the MP-T line. The Siemens QP series, including the Q160, is the manufacturer-approved and UL-listed direct replacement for Murray MP160 breakers.

Yes. The Siemens QP series is the direct descendant of the ITE EQ-P line. The Q160 can be used to replace an obsolete ITE 1-pole 60A breaker in panels that accept EQ-P types.

Standard thermal-magnetic breakers are rated for 80 percent continuous load. For this 60A breaker, the maximum continuous load is 48 amps.

Yes. This breaker is HACR rated, making it suitable for use with compatible heating, air conditioning, and refrigeration equipment that requires a 60A, 120VAC circuit.

As a 1-pole Type QP breaker, it requires a single 1-inch space in a compatible Siemens, ITE, or Murray load center.

Yes. The Q160 features lugs that are AL/CU rated, meaning they accept both aluminum and copper conductors. Ensure you use the correct wire gauge (8 to 2 AWG) and apply an approved oxide inhibitor if using aluminum wire.

The difference is the interrupting rating. The standard Q160 has a 10kAIC rating at 120V, while the Q160H is rated for 22kAIC. Verify your panel fault current requirements before selecting a breaker.

No. The Q160 is a standard thermal-magnetic breaker providing overload and short-circuit protection. It does not include ground-fault or arc-fault circuit interruption capabilities.
