Mars 83479 Single Pole Magnetic Circuit Breaker 20A

Product Description

The MARS 83479 is a single-pole, permanent magnetic circuit breaker rated at 20 amps. Circuit breakers of this type provide overcurrent protection by interrupting the circuit when current exceeds the rated threshold. The permanent magnetic design offers reliable trip response characteristics suited to HVAC control circuits, equipment branch circuits, and light commercial electrical panels. Licensed electricians and HVAC service technicians are the primary installers. At 20 amps and single-pole configuration, this breaker fits standard branch circuit applications where a compact, resettable protective device is required.

This breaker is suited for use in residential and light commercial applications where branch circuit overcurrent protection is needed. Permanent magnetic breakers are commonly found in HVAC equipment control panels, fan motor circuits, and auxiliary power circuits. They offer a manually resettable alternative to fuses in service environments where repeated reset capability reduces downtime during troubleshooting and maintenance.

Key Features

• 20-amp continuous current rating for standard branch circuit protection
• Single-pole configuration for 120-volt branch circuit applications
• Permanent magnetic trip mechanism for consistent overcurrent response
• Manually resettable design eliminates the need for fuse replacement
• Compact form factor suited for equipment panels and control enclosures

Compatibility

Designed as an OEM-style replacement or service breaker for single-pole, 20-amp permanent magnetic circuit breaker applications in HVAC equipment panels and light commercial control enclosures.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panel or equipment before removing or installing any circuit breaker. Verify the breaker amperage rating matches the circuit conductor size and load requirements before installation. Do not install in a panel or enclosure rated for a different breaker series without confirming mechanical and electrical compatibility.
