MP220 - 20 Amp Circuit Breaker

MP220 - 20 Amp Circuit Breaker

Finding the right breaker for your existing electrical system comes down to matching the details, not simply choosing something that looks similar. The Siemens MP220 circuit breaker is a 20-amp, 2-pole, 120/240V AC MP-T breaker with a 10 kA interrupting rating, designed for compatible residential electrical distribution equipment. Manufacturer specifications also identify the breaker as HACR-rated, with operation specified at ambient temperatures up to 40°C (104°F). When MP220 is the catalog number the equipment calls for, this is a purpose-built replacement designed to last and perform its intended circuit-protection function without changing the original system configuration.

Key Features and Benefits

• 20A current rating: Designed for circuits and equipment specifically requiring a 20-amp breaker.
• 2-pole configuration: Provides the pole arrangement required for compatible 120/240V applications.
• 120/240V AC rating: Matches electrical distribution equipment designed around this voltage configuration.
• Thermal-magnetic circuit protection: Uses the established thermal-magnetic operating design associated with the MP-T breaker family.
• MP-T design: Simplifies identification when replacing a breaker in compatible equipment that specifies this configuration.
• 50/60 Hz operation: Suitable for compatible systems operating at either 50 or 60 Hz.
• 40°C maximum operating ambient: Specified for operation at ambient temperatures up to 40°C (104°F).

Material Compliance and Certifications

The Siemens MP220 20A circuit breaker is identified in the manufacturer's specifications as HACR-rated. This rating helps confirm the breaker requirements for compatible heating, air-conditioning, and refrigeration equipment. However, the complete electrical application must still meet the equipment's requirements and applicable electrical codes.

Where It Works Best

The MP220 20A 2-pole circuit breaker works in compatible electrical distribution equipment that specifically requires the MP-T configuration together with a 20A rating, two poles, 120/240V AC operation, and a 10 kA interrupting rating. This is especially relevant for servicing legacy residential electrical systems where the goal is to maintain the original breaker configuration and electrical characteristics.
