Express Delivery Siemens / Murray MP130 – 30A 1 Pole Miniature Circuit Breaker

Handling higher current demands, this 30-amp single-pole breaker supplies robust thermal-magnetic protection for 120/240V systems. It is typically deployed for demanding residential applications like heavy-duty shop equipment. The unit integrates perfectly into legacy Murray panelboards and standard Siemens enclosures. By offering a precise fit for older systems, it helps avoid complete panel replacements, even though the Q130 has superseded it.
