Abb pm4222c Load Center 225A 42-circuit Nema 1

Product Description

The ABB pm4222c is a main circuit breaker load center rated at 225 amps with a 42-circuit capacity. It is designed for use in branch circuit distribution systems where incoming power is divided and protected across multiple circuits. The unit ships in a gray NEMA 1 enclosure, suited for indoor installations where a clean, dry environment is maintained. Licensed electricians install this type of load center in both residential and light commercial applications. The main circuit breaker provides disconnect capability, eliminating the need for a separate disconnect switch in qualifying installations.

This load center is used in indoor electrical distribution panels where 225-amp service capacity is required and up to 42 branch circuits must be protected. The NEMA 1 rating makes it appropriate for interior wall-mount installations in conditioned or semi-conditioned spaces. It is a practical choice for new construction, panel replacements, or service upgrades where a main breaker configuration is specified by the electrical design or local code.

Key Features

• 225-amp main circuit breaker rating provides whole-panel disconnect protection
• 42-circuit capacity supports a high number of branch circuits in a single enclosure
• NEMA 1 gray enclosure rated for indoor dry-location use
• Main circuit breaker (MCB) configuration eliminates need for a separate service disconnect in eligible applications
• Plug-on neutral (PON) design simplifies neutral bar connections during installation

Compatibility

Designed as an OEM-style distribution solution for indoor residential and light commercial branch circuit panelboard applications requiring 225-amp main breaker service and 42-circuit capacity.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Confirm that utility service capacity matches the 225-amp panel rating before installation. De-energize the service entrance conductors through the utility or an upstream disconnect before beginning work. Follow the panel manufacturer wiring instructions and torque requirements for all lugs and terminations as specified on the unit label.
