Siemens MP270 Double Pole Circuit Breaker 70A 120/240V

Product Description

The SIEMENS MP270 is a 70-amp, 2-pole circuit breaker rated for 120/240-volt residential and light commercial electrical panels. It provides overcurrent protection for branch circuits and feeder circuits, interrupting power automatically when current exceeds the rated amperage. This breaker is a standard plug-on style unit designed for installation by licensed electricians in load centers and distribution panels that accept the MP-frame form factor. At 0.617 pounds, it is compact enough for tight panel configurations while delivering reliable thermal-magnetic trip performance across both poles simultaneously.

The MP270 is suited for 120/240-volt single-phase applications including residential service panels and light commercial load centers. Typical applications include protection of 240-volt appliance circuits such as dryers, ranges, water heaters, and HVAC equipment feeder circuits. It is appropriate for both new construction installations and service panel upgrades where a 70-amp double-pole breaker is required.

Key Features

• 70-amp continuous current rating with thermal-magnetic trip mechanism
• 2-pole design protects both legs of a 120/240-volt circuit simultaneously
• Rated for 120/240-volt single-phase systems
• Compact form factor at 0.617 pounds for use in space-constrained panels
• Designed for plug-on installation in compatible load centers

Compatibility

Designed as an OEM-style replacement for residential and light commercial load centers accepting MP-frame double-pole circuit breakers.

Installation Notes

Installation must be performed by a qualified, licensed electrician in accordance with NFPA 70 (National Electrical Code) and all applicable local codes. De-energize the main breaker and verify with a non-contact voltage tester before handling any panel wiring or bus connections. Ensure the panel interior is rated for the MP-frame breaker series before installation. Never attempt installation with the service entrance conductors energized.
